PySide6.QtGraphs.QDateTimeAxis

class QDateTimeAxis

The QDateTimeAxis adds support for DateTime values to be added to a graph’s axis.

Details

A DateTime Axis can be used to display DateTime representations with tick marks and grid lines. The DateTime items on the axis are displayed at the position of the ticks.

Added in version 6.8.

Synopsis

Properties

• labelFormatᅟ - Format of the DateTime labels on the axis. The format property allows to signify the visual representation of the DateTime object, in days, months, and years. The default value is dd-MMMM-yy

• 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

• tickIntervalᅟ - Amount of major ticks are placed on an axis. If value is 0 or lower, axis will automatically calculate appropriate amount of ticks. The default value is 0

• timeZoneᅟ - Time zone that will be used to display labels of the axis. The accepted values are based on IANA time zone IDs. The default time zone is UTC

• visualMaxᅟ - Visual maximum value of the axis

• visualMinᅟ - Visual minimum value of the axis

• zoomᅟ - 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

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 format of the DateTime labels on the axis. The format property allows to signify the visual representation of the DateTime object, in days, months, and years. The default value is dd-MMMM-yy..

Access functions:

• labelFormat()

• setLabelFormat()

• Signal labelFormatChanged()

property maxᅟ: QDateTime

This property holds The maximum value on the axis.

This value can be lower or higher than the minimum. The DateTime is stored as UTC internally. The default value is new Date(1980,1,1)

Access functions:

• max()

• setMax()

• Signal maxChanged()

property minᅟ: QDateTime

This property holds The minimum value on the axis.

This value can be lower or higher than the maximum. The DateTime is stored as UTC internally. The default value is new Date(1970,1,1)

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 tickIntervalᅟ: float

This property holds The amount of major ticks are placed on an axis. If value is 0 or lower, axis will automatically calculate appropriate amount of ticks. The default value is 0..

Access functions:

• tickInterval()

• setTickInterval()

• Signal tickIntervalChanged()

property timeZoneᅟ: QTimeZone

This property holds The time zone that will be used to display labels of the axis. The accepted values are based on IANA time zone IDs. The default time zone is UTC..

Access functions:

• timeZone()

• setTimeZone()

• Signal timeZoneChanged()

property visualMaxᅟ: QDateTime

This property holds The visual maximum value of the axis..

This property holds a a visual maximum axis value when axis has been panned or zoomed. The default value is max

Access functions:

• visualMax()

• Signal visualMaxChanged()

property visualMinᅟ: QDateTime

This property holds The visual minimum value of the axis..

This property holds a a visual minimum axis value when axis has been panned or zoomed. The default value is min

Access functions:

• visualMin()

• Signal visualMinChanged()

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()
