Detailed Description
Manages a single axis inside a QCustomPlot.
Usually doesn't need to be instantiated externally. Access QCustomPlot's default four axes via QCustomPlot::xAxis (bottom), QCustomPlot::yAxis (left), QCustomPlot::xAxis2 (top) and QCustomPlot::yAxis2 (right).
Axes are always part of an axis rect, see QCPAxisRect.
Each axis holds an instance of QCPAxisTicker which is used to generate the tick coordinates and tick labels. You can access the currently installed ticker or set a new one (possibly one of the specialized subclasses, or your own subclass) via setTicker. For details, see the documentation of QCPAxisTicker.

Constructor & Destructor Documentation
◆ QCPAxis()
|
explicit |
Constructs an Axis instance of Type type for the axis rect parent.
Usually it isn't necessary to instantiate axes directly, because you can let QCustomPlot create them for you with QCPAxisRect::addAxis. If you want to use own QCPAxis-subclasses however, create them manually and then inject them also via QCPAxisRect::addAxis.

Member Function Documentation
◆ applyDefaultAntialiasingHint()
|
overrideprotectedvirtual |
A convenience function to easily set the QPainter::Antialiased hint on the provided painter before drawing axis lines.
This is the antialiasing state the painter passed to the draw method is in by default.
This function takes into account the local setting of the antialiasing flag as well as the overrides set with QCustomPlot::setAntialiasedElements and QCustomPlot::setNotAntialiasedElements.

◆ calculateMargin()
|
protectedvirtual |
Returns the appropriate outward margin for this axis. It is needed if QCPAxisRect::setAutoMargins is set to true on the parent axis rect. An axis with axis type atLeft will return an appropriate left margin, atBottom will return an appropriate bottom margin and so forth. For the calculation, this function goes through similar steps as draw, so changing one function likely requires the modification of the other one as well.
The margin consists of the outward tick length, tick label padding, tick label size, label padding, label size, and padding.
The margin is cached internally, so repeated calls while leaving the axis range, fonts, etc. unchanged are very fast.
Definition at line 9830 of file qcustomplot.cpp.
◆ coordToPixel()
double QCPAxis::coordToPixel | ( | double | value | ) | const |
Transforms value, in coordinates of the axis, to pixel coordinates of the QCustomPlot widget.
Definition at line 9305 of file qcustomplot.cpp.
◆ deselectEvent()
|
overrideprotectedvirtual |
This event is called when the layerable shall be deselected, either as consequence of a user interaction or a call to QCustomPlot::deselectAll. Subclasses should react to it by unsetting their selection appropriately.
just as in selectEvent, the output parameter selectionStateChanged (if non-null), must return true or false when the selection state of this layerable has changed or not changed, respectively.

Returns the font that is used to draw the axis label. Depending on the selection state, this is either mSelectedLabelFont or mLabelFont.
Definition at line 9791 of file qcustomplot.cpp.
◆ getPartAt()
QCPAxis::SelectablePart QCPAxis::getPartAt | ( | const QPointF & | pos | ) | const |
Returns the part of the axis that is hit by pos (in pixels). The return value of this function is independent of the user-selectable parts defined with setSelectableParts. Further, this function does not change the current selection state of the axis.
If the axis is not visible (setVisible), this function always returns spNone.

overrideprotectedvirtual |
This mouse event reimplementation provides the functionality to let the user drag individual axes exclusively, by startig the drag on top of the axis.
For the axis to accept this event and perform the single axis drag, the parent QCPAxisRect must be configured accordingly, i.e. it must allow range dragging in the orientation of this axis (QCPAxisRect::setRangeDrag) and this axis must be a draggable axis (QCPAxisRect::setRangeDragAxes)

◆ moveRange()
void QCPAxis::moveRange | ( | double | diff | ) |
If the scale type (setScaleType) is stLinear, diff is added to the lower and upper bounds of the range. The range is simply moved by diff.
If the scale type is stLogarithmic, the range bounds are multiplied by diff. This corresponds to an apparent "linear" move in logarithmic scaling by a distance of log(diff).

Returns the axis type that describes the opposite axis of an axis with the specified type.
Definition at line 9475 of file qcustomplot.cpp.
◆ orientation() [1/2]
|
inline |
Returns the orientation of this axis. The axis orientation (horizontal or vertical) is deduced from the axis type (left, top, right or bottom).
Definition at line 2309 of file qcustomplot.h.
◆ orientation() [2/2]
|
inlinestatic |
Returns the orientation of the specified axis type

Definition at line 2324 of file qcustomplot.h.
◆ padding()
|
inline |
Definition at line 2244 of file qcustomplot.h.
◆ pixelOrientation()
|
inline |
Returns which direction points towards higher coordinate values/keys, in pixel space.
This method returns either 1 or -1. If it returns 1, then going in the positive direction along the orientation of the axis in pixels corresponds to going from lower to higher axis coordinates. On the other hand, if this method returns -1, going to smaller pixel values corresponds to going from lower to higher axis coordinates.
For example, this is useful to easily shift axis coordinates by a certain amount given in pixels, without having to care about reversed or vertically aligned axes:
newKey will then contain a key that is ten pixels towards higher keys, starting from oldKey.
Definition at line 2310 of file qcustomplot.h.
◆ pixelToCoord()
double QCPAxis::pixelToCoord | ( | double | value | ) | const |
Transforms value, in pixel coordinates of the QCustomPlot widget, to axis coordinates.

◆ range()
|
inline |
Definition at line 2218 of file qcustomplot.h.
◆ rangeChanged [1/2]
|
signal |
This signal is emitted when the range of this axis has changed. You can connect it to the setRange slot of another axis to communicate the new range to the other axis, in order for it to be synchronized.
You may also manipulate/correct the range with setRange in a slot connected to this signal. This is useful if for example a maximum range span shall not be exceeded, or if the lower/upper range shouldn't go beyond certain values (see QCPRange::bounded). For example, the following slot would limit the x axis to ranges between 0 and 10:
◆ rangeChanged [2/2]
This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.
Additionally to the new range, this signal also provides the previous range held by the axis as oldRange.
◆ rangeReversed()
|
inline |
Definition at line 2219 of file qcustomplot.h.
◆ rescale()
void QCPAxis::rescale | ( | bool | onlyVisiblePlottables = false | ) |
Changes the axis range such that all plottables associated with this axis are fully visible in that dimension.
Definition at line 9219 of file qcustomplot.cpp.
◆ scaleRange() [1/2]
void QCPAxis::scaleRange | ( | double | factor | ) |
Scales the range of this axis by factor around the center of the current axis range. For example, if factor is 2.0, then the axis range will double its size, and the point at the axis range center won't have changed its position in the QCustomPlot widget (i.e. coordinates around the center will have moved symmetrically closer).
If you wish to scale around a different coordinate than the current axis range center, use the overload scaleRange(double factor, double center).
Definition at line 9142 of file qcustomplot.cpp.
◆ scaleRange() [2/2]
void QCPAxis::scaleRange | ( | double | factor, |
double | center ) |
This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.
Scales the range of this axis by factor around the coordinate center. For example, if factor is 2.0, center is 1.0, then the axis range will double its size, and the point at coordinate 1.0 won't have changed its position in the QCustomPlot widget (i.e. coordinates around 1.0 will have moved symmetrically closer to 1.0).

◆ selectEvent()
|
overrideprotectedvirtual |
This event is called when the layerable shall be selected, as a consequence of a click by the user. Subclasses should react to it by setting their selection state appropriately. The default implementation does nothing.
event is the mouse event that caused the selection. additive indicates, whether the user was holding the multi-select-modifier while performing the selection (see QCustomPlot::setMultiSelectModifier). if additive is true, the selection state must be toggled (i.e. become selected when unselected and unselected when selected).
Every selectEvent is preceded by a call to selectTest, which has returned positively (i.e. returned a value greater than 0 and less than the selection tolerance of the parent QCustomPlot). The details data you output from selectTest is fed back via details here. You may use it to transport any kind of information from the selectTest to the possibly subsequent selectEvent. Usually details is used to transfer which part was clicked, if it is a layerable that has multiple individually selectable parts (like QCPAxis). This way selectEvent doesn't need to do the calculation again to find out which part was actually clicked.
selectionStateChanged is an output parameter. If the pointer is non-null, this function must set the value either to true or false, depending on whether the selection state of this layerable was actually changed. For layerables that only are selectable as a whole and not in parts, this is simple: if additive is true, selectionStateChanged must also be set to true, because the selection toggles. If additive is false, selectionStateChanged is only set to true, if the layerable was previously unselected and now is switched to the selected state.

◆ selectionCategory()
|
overrideprotectedvirtual |
Returns the selection category this layerable shall belong to. The selection category is used in conjunction with QCustomPlot::setInteractions to control which objects are selectable and which aren't.
Subclasses that don't fit any of the normal QCP::Interaction values can use QCP::iSelectOther. This is what the default implementation returns.

◆ selectionChanged
|
signal |
This signal is emitted when the selection state of this axis has changed, either by user interaction or by a direct call to setSelectedParts.
◆ selectTest()
|
overridevirtual |
This function is used to decide whether a click hits a layerable object or not.
pos is a point in pixel coordinates on the QCustomPlot surface. This function returns the shortest pixel distance of this point to the object. If the object is either invisible or the distance couldn't be determined, -1.0 is returned. Further, if onlySelectable is true and the object is not selectable, -1.0 is returned, too.
If the object is represented not by single lines but by an area like a QCPItemText or the bars of a QCPBars plottable, a click inside the area should also be considered a hit. In these cases this function thus returns a constant value greater zero but still below the parent plot's selection tolerance. (typically the selectionTolerance multiplied by 0.99).
Providing a constant value for area objects allows selecting line objects even when they are obscured by such area objects, by clicking close to the lines (i.e. closer than 0.99*selectionTolerance).
The actual setting of the selection state is not done by this function. This is handled by the parent QCustomPlot when the mouseReleaseEvent occurs, and the finally selected object is notified via the selectEvent/ deselectEvent methods.
details is an optional output parameter. Every layerable subclass may place any information in details. This information will be passed to selectEvent when the parent QCustomPlot decides on the basis of this selectTest call, that the object was successfully selected. The subsequent call to selectEvent will carry the details. This is useful for multi-part objects (like QCPAxis). This way, a possibly complex calculation to decide which part was clicked is only done once in selectTest. The result (i.e. the actually clicked part) can then be placed in details. So in the subsequent selectEvent, the decision which part was selected doesn't have to be done a second time for a single selection operation.
In the case of 1D Plottables (QCPAbstractPlottable1D, like QCPGraph or QCPBars) details will be set to a QCPDataSelection, describing the closest data point to pos.
You may pass nullptr
as details to indicate that you are not interested in those selection details.

◆ setLowerEnding()
void QCPAxis::setLowerEnding | ( | const QCPLineEnding & | ending | ) |
Sets the style for the lower axis ending. See the documentation of QCPLineEnding for available styles.
For horizontal axes, this method refers to the left ending, for vertical axes the bottom ending. Note that this meaning does not change when the axis range is reversed with setRangeReversed.
- See also
- setUpperEnding
Definition at line 9090 of file qcustomplot.cpp.
◆ setNumberFormat()
void QCPAxis::setNumberFormat | ( | const QString & | formatCode | ) |
Sets the number format for the numbers in tick labels. This formatCode is an extended version of the format code used e.g. by QString::number() and QLocale::toString(). For reference about that, see the "Argument Formats" section in the detailed description of the QString class.
formatCode is a string of one, two or three characters.
The first character is identical to the normal format code used by Qt. In short, this means: 'e'/'E' scientific format, 'f' fixed format, 'g'/'G' scientific or fixed, whichever is shorter. For the 'e', 'E', and 'f' formats, the precision set by setNumberPrecision represents the number of digits after the decimal point. For the 'g' and 'G' formats, the precision represents the maximum number of significant digits, trailing zeroes are omitted.
The second and third characters are optional and specific to QCustomPlot:
If the first char was 'e' or 'g', numbers are/might be displayed in the scientific format, e.g. "5.5e9", which is ugly in a plot. So when the second char of formatCode is set to 'b' (for "beautiful"), those exponential numbers are formatted in a more natural way, i.e. "5.5
[multiplication sign] 10 [superscript] 9". By default, the multiplication sign is a centered dot. If instead a cross should be shown (as is usual in the USA), the third char of formatCode can be set to 'c'. The inserted multiplication signs are the UTF-8 characters 215 (0xD7) for the cross and 183 (0xB7) for the dot.
Examples for formatCode:
g
normal format code behaviour. If number is small, fixed format is used, if number is large, normal scientific format is usedgb
If number is small, fixed format is used, if number is large, scientific format is used with beautifully typeset decimal powers and a dot as multiplication signebc
All numbers are in scientific format with beautifully typeset decimal power and a cross as multiplication signfb
illegal format code, since fixed format doesn't support (or need) beautifully typeset decimal powers. Format code will be reduced to 'f'.hello
illegal format code, since first char is not 'e', 'E', 'f', 'g' or 'G'. Current format code will not be changed.
Definition at line 8716 of file qcustomplot.cpp.
◆ setNumberPrecision()
void QCPAxis::setNumberPrecision | ( | int | precision | ) |
Sets the precision of the tick label numbers. See QLocale::toString(double i, char f, int prec) for details. The effect of precisions are most notably for number Formats starting with 'e', see setNumberFormat
Definition at line 8776 of file qcustomplot.cpp.
◆ setOffset()
void QCPAxis::setOffset | ( | int | offset | ) |
Sets the offset the axis has to its axis rect side.
If an axis rect side has multiple axes and automatic margin calculation is enabled for that side, only the offset of the inner most axis has meaning (even if it is set to be invisible). The offset of the other, outer axes is controlled automatically, to place them at appropriate positions.
Definition at line 8997 of file qcustomplot.cpp.
◆ setPadding()
void QCPAxis::setPadding | ( | int | padding | ) |
Sets the padding of the axis.
When QCPAxisRect::setAutoMargins is enabled, the padding is the additional outer most space, that is left blank.
The axis padding has no meaning if QCPAxisRect::setAutoMargins is disabled.

Definition at line 8980 of file qcustomplot.cpp.
◆ setRange() [1/3]
void QCPAxis::setRange | ( | const QCPRange & | range | ) |
Sets the range of the axis.
This slot may be connected with the rangeChanged signal of another axis so this axis is always synchronized with the other axis range, when it changes.
To invert the direction of an axis, use setRangeReversed.
Definition at line 8391 of file qcustomplot.cpp.
◆ setRange() [2/3]
void QCPAxis::setRange | ( | double | lower, |
double | upper ) |
This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.
Sets the lower and upper bound of the axis range.
To invert the direction of an axis, use setRangeReversed.
There is also a slot to set a range, see setRange(const QCPRange &range).
Definition at line 8461 of file qcustomplot.cpp.
◆ setRange() [3/3]
void QCPAxis::setRange | ( | double | position, |
double | size, | ||
Qt::AlignmentFlag | alignment ) |
This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.
Sets the range of the axis.
The position coordinate indicates together with the alignment parameter, where the new range will be positioned. size defines the size of the new axis range. alignment may be Qt::AlignLeft, Qt::AlignRight or Qt::AlignCenter. This will cause the left border, right border, or center of the range to be aligned with position. Any other values of alignment will default to Qt::AlignCenter.
Definition at line 8492 of file qcustomplot.cpp.
◆ setRangeLower()
void QCPAxis::setRangeLower | ( | double | lower | ) |
Sets the lower bound of the axis range. The upper bound is not changed.
- See also
- setRange
Definition at line 8506 of file qcustomplot.cpp.
◆ setRangeReversed()
void QCPAxis::setRangeReversed | ( | bool | reversed | ) |
Sets whether the axis range (direction) is displayed reversed. Normally, the values on horizontal axes increase left to right, on vertical axes bottom to top. When reversed is set to true, the direction of increasing values is inverted.
Note that the range and data interface stays the same for reversed axes, e.g. the lower part of the setRange interface will still reference the mathematically smaller number than the upper part.
Definition at line 8555 of file qcustomplot.cpp.
◆ setRangeUpper()
void QCPAxis::setRangeUpper | ( | double | upper | ) |
Sets the upper bound of the axis range. The lower bound is not changed.
- See also
- setRange
Definition at line 8528 of file qcustomplot.cpp.
◆ setScaleRatio()
void QCPAxis::setScaleRatio | ( | const QCPAxis * | otherAxis, |
double | ratio = 1.0 ) |
Scales the range of this axis to have a certain scale ratio to otherAxis. The scaling will be done around the center of the current axis range.
For example, if ratio is 1, this axis is the yAxis and otherAxis is xAxis, graphs plotted with those axes will appear in a 1:1 aspect ratio, independent of the aspect ratio the axis rect has.
This is an operation that changes the range of this axis once, it doesn't fix the scale ratio indefinitely. Note that calling this function in the constructor of the QCustomPlot's parent won't have the desired effect, since the widget dimensions aren't defined yet, and a resizeEvent will follow.
Definition at line 9195 of file qcustomplot.cpp.
◆ setScaleType()
void QCPAxis::setScaleType | ( | QCPAxis::ScaleType | type | ) |
Sets whether the axis uses a linear scale or a logarithmic scale.
Note that this method controls the coordinate transformation. For logarithmic scales, you will likely also want to use a logarithmic tick spacing and labeling, which can be achieved by setting the axis ticker to an instance of QCPAxisTickerLog :
See the documentation of QCPAxisTickerLog about the details of logarithmic axis tick creation.
Definition at line 8371 of file qcustomplot.cpp.
◆ setSelectableParts()
void QCPAxis::setSelectableParts | ( | const QCPAxis::SelectableParts & | selectableParts | ) |
Sets whether the user can (de-)select the parts in selectable by clicking on the QCustomPlot surface. (When QCustomPlot::setInteractions contains iSelectAxes.)
However, even when selectable is set to a value not allowing the selection of a specific part, it is still possible to set the selection of this part manually, by calling setSelectedParts directly.

Definition at line 9021 of file qcustomplot.cpp.
◆ setSelectedParts()
void QCPAxis::setSelectedParts | ( | const QCPAxis::SelectableParts & | selectedParts | ) |
Sets the selected state of the respective axis parts described by SelectablePart. When a part is selected, it uses a different pen/font.
The entire selection mechanism for axes is handled automatically when QCustomPlot::setInteractions contains iSelectAxes. You only need to call this function when you wish to change the selection state manually.
This function can change the selection state of a part, independent of the setSelectableParts setting.
emits the selectionChanged signal when selected is different from the previous selection state.

Definition at line 9065 of file qcustomplot.cpp.
◆ setSubTickLength()
void QCPAxis::setSubTickLength | ( | int | inside, |
int | outside = 0 ) |
Sets the length of the subticks in pixels. inside is the length the subticks will reach inside the plot and outside is the length they will reach outside the plot. If outside is greater than zero, the tick labels and axis label will increase their distance to the axis accordingly, so they won't collide with the ticks.
Definition at line 8853 of file qcustomplot.cpp.
◆ setSubTickLengthIn()
void QCPAxis::setSubTickLengthIn | ( | int | inside | ) |
Sets the length of the inward subticks in pixels. inside is the length the subticks will reach inside the plot.

Definition at line 8836 of file qcustomplot.cpp.
◆ setTicker()
void QCPAxis::setTicker | ( | QSharedPointer< QCPAxisTicker > | ticker | ) |
The axis ticker is responsible for generating the tick positions and tick labels. See the documentation of QCPAxisTicker for details on how to work with axis tickers.
You can change the tick positioning/labeling behaviour of this axis by setting a different QCPAxisTicker subclass using this method. If you only wish to modify the currently installed axis ticker, access it via ticker.
Since the ticker is stored in the axis as a shared pointer, multiple axes may share the same axis ticker simply by passing the same shared pointer to multiple axes.

Definition at line 8617 of file qcustomplot.cpp.
◆ setTickLabelRotation()
void QCPAxis::setTickLabelRotation | ( | double | degrees | ) |
Sets the rotation of the tick labels. If degrees is zero, the labels are drawn normally. Else, the tick labels are drawn rotated by degrees clockwise. The specified angle is bound to values from -90 to 90 degrees.
If degrees is exactly -90, 0 or 90, the tick labels are centered on the tick coordinate. For other angles, the label is drawn with an offset such that it seems to point toward or away from the tick mark.
Definition at line 8659 of file qcustomplot.cpp.
◆ setTickLabels()
void QCPAxis::setTickLabels | ( | bool | show | ) |
Sets whether tick labels are displayed. Tick labels are the numbers drawn next to tick marks.
Definition at line 8602 of file qcustomplot.cpp.
◆ setTickLabelSide()
void QCPAxis::setTickLabelSide | ( | LabelSide | side | ) |
Sets whether the tick labels (numbers) shall appear inside or outside the axis rect.
The usual and default setting is lsOutside. Very compact plots sometimes require tick labels to be inside the axis rect, to save space. If side is set to lsInside, the tick labels appear on the inside are additionally clipped to the axis rect.
Definition at line 8675 of file qcustomplot.cpp.
◆ setTickLength()
void QCPAxis::setTickLength | ( | int | inside, |
int | outside = 0 ) |
Sets the length of the ticks in pixels. inside is the length the ticks will reach inside the plot and outside is the length they will reach outside the plot.

◆ setUpperEnding()
void QCPAxis::setUpperEnding | ( | const QCPLineEnding & | ending | ) |
Sets the style for the upper axis ending. See the documentation of QCPLineEnding for available styles.
For horizontal axes, this method refers to the right ending, for vertical axes the top ending. Note that this meaning does not change when the axis range is reversed with setRangeReversed.
- See also

◆ setupTickVectors()
|
protected |
Prepares the internal tick vector, sub tick vector and tick label vector. This is done by calling QCPAxisTicker::generate on the currently installed ticker.
If a change in the label text/count is detected, the cached axis margin is invalidated to make sure the next margin calculation recalculates the label sizes and returns an up-to-date value.

Returns a modifiable shared pointer to the currently installed axis ticker. The axis ticker is responsible for generating the tick positions and tick labels of this axis. You can access the QCPAxisTicker with this method and modify basic properties such as the approximate tick count (QCPAxisTicker::setTickCount).
You can gain more control over the axis ticks by setting a different QCPAxisTicker subclass, see the documentation there. A new axis ticker can be set with setTicker.
Since the ticker is stored in the axis as a shared pointer, multiple axes may share the same axis ticker simply by passing the same shared pointer to multiple axes.

This mouse event reimplementation provides the functionality to let the user zoom individual axes exclusively, by performing the wheel event on top of the axis.
For the axis to accept this event and perform the single axis zoom, the parent QCPAxisRect must be configured accordingly, i.e. it must allow range zooming in the orientation of this axis (QCPAxisRect::setRangeZoom) and this axis must be a zoomable axis (QCPAxisRect::setRangeZoomAxes)
\seebaseclassmethod
- Note
- The zooming of possibly multiple axes at once by performing the wheel event anywhere in the axis rect is handled by the axis rect's mouse event, e.g. QCPAxisRect::wheelEvent.
Reimplemented from QCPLayerable.
