class QValueAxis¶

The QValueAxis class adds values to a graph’s axes. More…

Inherited by: QCategoryAxis

Synopsis¶

Properties¶

labelFormatᅟ - Label format of the axis
maxᅟ - Maximum value on the axis
minᅟ - Minimum value on the axis
minorTickCountᅟ
tickAnchorᅟ - Base value where the dynamically placed tick marks and labels are started from. The default value is 0
tickCountᅟ
tickIntervalᅟ - Interval between dynamically placed tick marks and labels. The default value is 0, which means that intervals are automatically calculated based on the min and max range

Detailed Description¶

A value axis can be set up to show an axis line with tick marks, grid lines, and shades. The values on the axis are drawn at the positions of tick marks.

class TickType¶

Note

Properties can be used directly when from __feature__ import true_property is used or via accessor functions otherwise.

property labelFormatᅟ: str¶

This property holds The label format of the axis..

The format string supports the following conversion specifiers, length modifiers, and flags provided by printf() in the standard C++ library: d, i, o, x, X, f, F, e, E, g, G, c.

The default value is empty, in which case ‘f’ format is used.

asprintf()

Access functions:

labelFormat()
setLabelFormat()
Signal labelFormatChanged()

property maxᅟ: float¶

This property holds The maximum value on the axis..

When setting this property, the minimum value is adjusted if necessary, to ensure that the range remains valid. The default value is 10.0

Access functions:

max()
setMax()
Signal maxChanged()

property minᅟ: float¶

This property holds The minimum value on the axis..

When setting this property, the maximum value is adjusted if necessary, to ensure that the range remains valid. The default value is 0.0

Access functions:

min()
setMin()
Signal minChanged()

property minorTickCountᅟ: int¶

Access functions:

minorTickCount()
setMinorTickCount()
Signal minorTickCountChanged()

property tickAnchorᅟ: float¶

This property holds The base value where the dynamically placed tick marks and labels are started from. The default value is 0..

Access functions:

tickAnchor()
setTickAnchor()
Signal tickAnchorChanged()

property tickCountᅟ: int¶

Access functions:

tickCount()
setTickCount()
Signal tickCountChanged()

property tickIntervalᅟ: float¶

This property holds The interval between dynamically placed tick marks and labels. The default value is 0, which means that intervals are automatically calculated based on the min and max range..

Access functions:

tickInterval()
setTickInterval()
Signal tickIntervalChanged()

property tickTypeᅟ: QValueAxis.TickType¶

Access functions:

tickType()
setTickType()
Signal tickTypeChanged()
