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.

Naming convention of axis parts

Overview of the spacings and paddings that define the geometry of an axis. The dashed gray line on the left represents the QCustomPlot widget border.

Definition at line 985 of file qcustomplot.h.

Member Enumeration Documentation

enum QCPAxis::AxisType

Defines at which side of the axis rect the axis will appear. This also affects how the tick marks are drawn, on which side the labels are placed etc.

Enumerator
atLeft	`0x01` Axis is vertical and on the left side of the axis rect
atRight	`0x02` Axis is vertical and on the right side of the axis rect
atTop	`0x04` Axis is horizontal and on the top side of the axis rect
atBottom	`0x08` Axis is horizontal and on the bottom side of the axis rect

Definition at line 1047 of file qcustomplot.h.

enum QCPAxis::LabelSide

Defines on which side of the axis the tick labels (numbers) shall appear.

See also: setTickLabelSide

Enumerator
lsInside	Tick labels will be displayed inside the axis rect and clipped to the inner axis rect.
lsOutside	Tick labels will be displayed outside the axis rect.

Definition at line 1069 of file qcustomplot.h.

enum QCPAxis::LabelType

When automatic tick label generation is enabled (setAutoTickLabels), defines how the coordinate of the tick is interpreted, i.e. translated into a string.

See also: setTickLabelType

Enumerator
ltNumber	Tick coordinate is regarded as normal number and will be displayed as such. (see setNumberFormat)
ltDateTime	Tick coordinate is regarded as a date/time (seconds since 1970-01-01T00:00:00 UTC) and will be displayed and formatted as such. (for details, see setDateTimeFormat)

Definition at line 1060 of file qcustomplot.h.

enum QCPAxis::ScaleType

Defines the scale of an axis.

See also: setScaleType

Enumerator
stLinear	Linear scaling.
stLogarithmic	Logarithmic scaling with correspondingly transformed plots and (major) tick marks at every base power (see setScaleLogBase).

Definition at line 1077 of file qcustomplot.h.

enum QCPAxis::SelectablePart

Defines the selectable parts of an axis.

See also: setSelectableParts, setSelectedParts

Enumerator
spNone	None of the selectable parts.
spAxis	The axis backbone and tick marks.
spTickLabels	Tick labels (numbers) of this axis (as a whole, not individually)
spAxisLabel	The axis label.

Definition at line 1085 of file qcustomplot.h.

Constructor & Destructor Documentation

QCPAxis::QCPAxis	(	QCPAxisRect *	parent,
		AxisType	type
	)

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.

void QCPAxis::selectionChanged ( const QCPAxis::SelectableParts & parts )

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.

double QCPAxis::selectTest	(	const QPointF &	pos,
		bool	onlySelectable,
		QVariant *	details = `0`
	)		const

virtual

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 item is represented not by single lines but by an area like QCPItemRect or QCPItemText, a click inside the area returns a constant value greater zero (typically the selectionTolerance of the parent QCustomPlot multiplied by 0.99). If the click lies outside the area, this function returns -1.0.

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.

You may pass 0 as details to indicate that you are not interested in those selection details.

void QCPAxis::setAutoSubTicks ( bool on )

Sets whether the number of sub ticks in one tick interval is determined automatically. This works, as long as the tick step mantissa is a multiple of 0.5. When setAutoTickStep is enabled, this is always the case.

When on is set to false, you may set the sub tick count with setSubTickCount manually.

See also: setAutoTickCount, setAutoTicks, setAutoTickStep

Definition at line 4495 of file qcustomplot.cpp.

void QCPAxis::setAutoTickCount ( int approximateCount )

When setAutoTickStep is true, approximateCount determines how many ticks should be generated in the visible range, approximately.

It's not guaranteed that this number of ticks is met exactly, but approximately within a tolerance of about two.

Only values greater than zero are accepted as approximateCount.

See also: setAutoTickStep, setAutoTicks, setAutoSubTicks

Definition at line 4428 of file qcustomplot.cpp.

void QCPAxis::setAutoTickLabels ( bool on )

Sets whether the tick labels are generated automatically. Depending on the tick label type (ltNumber or ltDateTime), the labels will either show the coordinate as floating point number (setNumberFormat), or a date/time formatted according to setDateTimeFormat.

If on is set to false, you should provide the tick labels via setTickVectorLabels. This is usually used in a combination with setAutoTicks set to false for complete control over tick positions and labels, e.g. when the ticks should be at multiples of pi and show "2pi", "3pi" etc. as tick labels.

If you need dynamically calculated tick vectors (and possibly tick label vectors), set the vectors in a slot connected to the ticksRequest signal.

See also: setAutoTicks

Definition at line 4456 of file qcustomplot.cpp.

void QCPAxis::setAutoTicks ( bool on )

Sets whether the tick positions should be calculated automatically (either from an automatically generated tick step or a tick step provided manually via setTickStep, see setAutoTickStep).

If on is set to false, you must provide the tick positions manually via setTickVector. For these manual ticks you may let QCPAxis generate the appropriate labels automatically by leaving setAutoTickLabels set to true. If you also wish to control the displayed labels manually, set setAutoTickLabels to false and provide the label strings with setTickVectorLabels.

If you need dynamically calculated tick vectors (and possibly tick label vectors), set the vectors in a slot connected to the ticksRequest signal.

See also: setAutoTickLabels, setAutoSubTicks, setAutoTickCount, setAutoTickStep

Definition at line 4408 of file qcustomplot.cpp.

void QCPAxis::setAutoTickStep ( bool on )

Sets whether the tick step, i.e. the interval between two (major) ticks, is calculated automatically. If on is set to true, the axis finds a tick step that is reasonable for human readable plots.

The number of ticks the algorithm aims for within the visible range can be specified with setAutoTickCount.

If on is set to false, you may set the tick step manually with setTickStep.

void QCPAxis::setDateTimeFormat ( const QString & format )

Sets the format in which dates and times are displayed as tick labels, if setTickLabelType is ltDateTime. for details about the format string, see the documentation of QDateTime::toString().

Newlines can be inserted with "\n".

See also: setDateTimeSpec

Definition at line 4641 of file qcustomplot.cpp.

void QCPAxis::setDateTimeSpec ( const Qt::TimeSpec & timeSpec )

Sets the time spec that is used for the date time values when setTickLabelType is ltDateTime.

The default value of QDateTime objects (and also QCustomPlot) is Qt::LocalTime. However, if the date time values passed to QCustomPlot are given in the UTC spec, set timeSpec to Qt::UTC to get the correct axis labels.

Definition at line 4660 of file qcustomplot.cpp.

void QCPAxis::setLabel ( const QString & str )

Sets the text of the axis label that will be shown below/above or next to the axis, depending on its orientation. To disable axis labels, pass an empty string as str.

Definition at line 4990 of file qcustomplot.cpp.

void QCPAxis::setLabelColor ( const QColor & color )

Sets the color of the axis label.

See also: setLabelFont

void QCPAxis::setLabelPadding ( int padding )

Sets the distance between the tick labels and the axis label.

See also: setTickLabelPadding, setPadding

Definition at line 5004 of file qcustomplot.cpp.

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 5133 of file qcustomplot.cpp.

void QCPAxis::setNumberFormat ( const QString & formatCode )

Sets the number format for the numbers drawn as tick labels (if tick label type is ltNumber). 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.

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.

If the scale type (setScaleType) is stLogarithmic and the formatCode uses the 'b' option (beautifully typeset decimal powers), the display usually is "1 [multiplication sign] 10 [superscript] n", which looks unnatural for logarithmic scaling (the "1 [multiplication sign]" part). To only display the decimal power, set the number precision to zero with setNumberPrecision.

Examples for formatCode:

g normal format code behaviour. If number is small, fixed format is used, if number is large, normal scientific format is used
gb 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 sign
ebc All numbers are in scientific format with beautifully typeset decimal power and a cross as multiplication sign
fb 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 4701 of file qcustomplot.cpp.

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

If the scale type (setScaleType) is stLogarithmic and the number format (setNumberFormat) uses the 'b' format code (beautifully typeset decimal powers), the display usually is "1 [multiplication sign] 10 [superscript] n", which looks unnatural for logarithmic scaling (the redundant "1 [multiplication sign]" part). To only display the decimal power "10 [superscript] n", set precision to zero.

Definition at line 4767 of file qcustomplot.cpp.

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 5040 of file qcustomplot.cpp.

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.

See also: setLabelPadding, setTickLabelPadding

Definition at line 5023 of file qcustomplot.cpp.

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 4216 of file qcustomplot.cpp.

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 4287 of file qcustomplot.cpp.

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 4319 of file qcustomplot.cpp.

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 4333 of file qcustomplot.cpp.

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 4384 of file qcustomplot.cpp.

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 4356 of file qcustomplot.cpp.

void QCPAxis::setScaleLogBase ( double base )

If setScaleType is set to stLogarithmic, base will be the logarithm base of the scaling. In logarithmic axis scaling, major tick marks appear at all powers of base.

Properties like tick step (setTickStep) don't apply in logarithmic scaling. If you wish a decimal base but less major ticks, consider choosing base 100, 1000 or even higher.

Definition at line 4197 of file qcustomplot.cpp.

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 5223 of file qcustomplot.cpp.

void QCPAxis::setScaleType ( QCPAxis::ScaleType type )

Sets whether the axis uses a linear scale or a logarithmic scale. If type is set to stLogarithmic, the logarithm base can be set with setScaleLogBase. In logarithmic axis scaling, major tick marks appear at all powers of the logarithm base. Properties like tick step (setTickStep) don't apply in logarithmic scaling. If you wish a decimal base but less major ticks, consider choosing a logarithm base of 100, 1000 or even higher.

If type is stLogarithmic and the number format (setNumberFormat) uses the 'b' option (beautifully typeset decimal powers), the display usually is "1 [multiplication sign] 10 [superscript] n", which looks unnatural for logarithmic scaling (the "1 [multiplication sign]" part). To only display the decimal power, set the number precision to zero with setNumberPrecision.

Definition at line 4178 of file qcustomplot.cpp.

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.

See also: SelectablePart, setSelectedParts

Definition at line 4245 of file qcustomplot.cpp.

See also: setLabelFont, setSelectableParts, setSelectedParts, QCustomPlot::setInteractions

Definition at line 5064 of file qcustomplot.cpp.

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.

void QCPAxis::setSubTickCount ( int count )

Sets the number of sub ticks in one (major) tick step. A sub tick count of three for example, divides the tick intervals in four sub intervals.

By default, the number of sub ticks is chosen automatically in a reasonable manner as long as the mantissa of the tick step is a multiple of 0.5. When setAutoTickStep is enabled, this is always the case.

If you want to disable automatic sub tick count and use this function to set the count manually, see setAutoSubTicks.

Definition at line 4883 of file qcustomplot.cpp.

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 4535 of file qcustomplot.cpp.

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 4611 of file qcustomplot.cpp.

void QCPAxis::setTickLabels ( bool show )

Sets whether tick labels are displayed. Tick labels are the numbers drawn next to tick marks.

Definition at line 4522 of file qcustomplot.cpp.

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 4627 of file qcustomplot.cpp.

void QCPAxis::setTickLabelType ( LabelType type )

Sets whether the tick labels display numbers or dates/times.

If type is set to ltNumber, the format specifications of setNumberFormat apply.

If type is set to ltDateTime, the format specifications of setDateTimeFormat apply.

In QCustomPlot, date/time coordinates are double numbers representing the seconds since 1970-01-01T00:00:00 UTC. This format can be retrieved from QDateTime objects with the QDateTime::toTime_t() function. Since this only gives a resolution of one second, there is also the QDateTime::toMSecsSinceEpoch() function which returns the timespan described above in milliseconds. Divide its return value by 1000.0 to get a value with the format needed for date/time plotting, with a resolution of one millisecond.

Using the toMSecsSinceEpoch function allows dates that go back to 2nd January 4713 B.C. (represented by a negative number), unlike the toTime_t function, which works with unsigned integers and thus only goes back to 1st January 1970. So both for range and accuracy, use of toMSecsSinceEpoch()/1000.0 should be preferred as key coordinate for date/time axes.

void QCPAxis::setTicks ( bool show )

Sets whether tick marks are displayed.

Note that setting show to false does not imply that tick labels are invisible, too. To achieve that, see setTickLabels.

Definition at line 4510 of file qcustomplot.cpp.

void QCPAxis::setTickStep ( double step )

If setAutoTickStep is set to false, use this function to set the tick step manually. The tick step is the interval between (major) ticks, in plot coordinates.

See also: setSubTickCount

Definition at line 4781 of file qcustomplot.cpp.

void QCPAxis::setTickVector ( const QVector< double > & vec )

If you want full control over what ticks (and possibly labels) the axes show, this function is used to set the coordinates at which ticks will appear.setAutoTicks must be disabled, else the provided tick vector will be overwritten with automatically generated tick coordinates upon replot. The labels of the ticks can be generated automatically when setAutoTickLabels is left enabled. If it is disabled, you can set the labels manually with setTickVectorLabels.

vec is a vector containing the positions of the ticks, in plot coordinates.

Warning: vec must be sorted in ascending order, no additional checks are made to ensure this.

See also: setTickVectorLabels

Definition at line 4803 of file qcustomplot.cpp.

void QCPAxis::setTickVectorLabels ( const QVector< QString > & vec )

If you want full control over what ticks and labels the axes show, this function is used to set a number of QStrings that will be displayed at the tick positions which you need to provide with setTickVector. These two vectors should have the same size. (Note that you need to disable setAutoTicks and setAutoTickLabels first.)

vec is a vector containing the labels of the ticks. The entries correspond to the respective indices in the tick vector, passed via setTickVector.

Definition at line 4821 of file qcustomplot.cpp.

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.

signal

This signal is emitted when setAutoTicks is false and the axis is about to generate tick labels for a replot.

Modifying the tick positions can be done with setTickVector. If you also want to control the tick labels, set setAutoTickLabels to false and also provide the labels with setTickVectorLabels.

If you only want static ticks you probably don't need this signal, since you can just set the tick vector (and possibly tick label vector) once. However, if you want to provide ticks (and maybe labels) dynamically, e.g. depending on the current axis range, connect a slot to this signal and set the vector/vectors there.
