PySide6.QtGraphs.QValueAxis

class QValueAxis

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

Synopsis

Properties

• labelDecimalsᅟ - Number of decimals used for showing the labels. When set to -1, decimal amount is adjusted automatically based on the values range. The default value is -1

• labelFormatᅟ - Label format of the axis

• maxᅟ - Maximum value on the axis

• minᅟ - Minimum value on the axis

• panᅟ - Value of the axis

• subTickCountᅟ - Number of subticks on the axis. This indicates how many subticks are drawn between major lines on the graph. Labels are not drawn for subticks. The default value is 0

• tickAnchorᅟ - Base value where the dynamically placed tick marks and labels are started from. The default value is 0

• 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

• zoomᅟ - Value of the axis

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.

Note

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

property labelDecimalsᅟ: int

This property holds The number of decimals used for showing the labels. When set to -1, decimal amount is adjusted automatically based on the values range. The default value is -1..

Access functions:

• labelDecimals()

• setLabelDecimals()

• Signal labelDecimalsChanged()

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.

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 panᅟ: float

This property holds The pan value of the axis..

The pan value moves the center of the axis without affecting intervals of grid and labels. The default value is 0.

Access functions:

• pan()

• setPan()

• Signal panChanged()

property subTickCountᅟ: int

This property holds The number of subticks on the axis. This indicates how many subticks are drawn between major lines on the graph. Labels are not drawn for subticks. The default value is 0..

Access functions:

• subTickCount()

• setSubTickCount()

• Signal subTickCountChanged()

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 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 zoomᅟ: float

This property holds The zoom value of the axis..

The zoom value enlarges or shrinks the axis and thus the graph without affecting intervals of grid and labels. The default value is 1.

Access functions:

• zoom()

• setZoom()

• Signal zoomChanged()
