DateTimeScaleEngine

class DateTimeScaleEngine(scaleDraw=None)

Bases: PyQt4.Qwt5.Qwt.QwtLinearScaleEngine

static disableInAxis(plot, axis, scaleDraw=None, scaleEngine=None)

convenience method that will disable this engine in the given axis. Note that it changes the ScaleDraw as well.

Parameters:

• plot (:class:~`Qwt5.QwtPlot`) – the plot to change
• axis (:class:~`Qwt5.QwtPlot.Axis`) – the id of the axis
• scaleDraw (:class:~`Qwt5.QwtScaleDraw`) – Scale draw to use. If None given, a FancyScaleDraw will be set
• scaleEngine (:class:~`Qwt5.QwtScaleEngine`) – Scale draw to use. If None given, a Qwt5.QwtLinearScaleEngine will be set

divideScale(x1, x2, maxMajSteps, maxMinSteps, stepSize)

Reimplements Qwt5.QwtLinearScaleEngine.divideScale

Important: The stepSize parameter is ignored.

Return type::class:~`Qwt5.QwtScaleDiv` Returns:a scale division whose ticks are aligned with the natural time units

static enableInAxis(plot, axis, scaleDraw=None, rotation=None)

convenience method that will enable this engine in the given axis. Note that it changes the ScaleDraw as well.

Parameters:

• plot (:class:~`Qwt5.QwtPlot`) – the plot to change
• axis (:class:~`Qwt5.QwtPlot.Axis`) – the id of the axis
• scaleDraw (:class:~`Qwt5.QwtScaleDraw`) – Scale draw to use. If None given, the current ScaleDraw for the plot will be used if possible, and a TaurusTimeScaleDraw will be set if not
• rotation (:class:~`float` or :class:~`None`) – The rotation of the labels (in degrees, clockwise-positive)

static getDefaultAxisLabelsAlignment(axis, rotation)

return a “smart” alignment for the axis labels depending on the axis and the label rotation

Parameters:

• axis (:class:~`Qwt5.QwtPlot.Axis`) – the axis
• rotation (:class:~`float`) – The rotation (in degrees, clockwise-positive)

Return type:

:class:~`Qt.Alignment`

Returns:

an alignment
