FillBetweenItem

class pyqtgraph.FillBetweenItem(curve1, curve2, brush=None, pen=None, fillRule=FillRule.OddEvenFill)

GraphicsItem filling the space between two PlotDataItems.

__init__(curve1, curve2, brush=None, pen=None, fillRule=FillRule.OddEvenFill)

FillBetweenItem fills a region between two curves with a specified QBrush.

Parameters:

• curve1 (PlotDataItem | PlotCurveItem) – Line to draw fill from

• curve2 (PlotDataItem | PlotCurveItem) – Line to draw fill to

• brush (pyqtgraph.mkColor(), optional) – Arguments accepted by mkBrush(), used to create the QBrush instance used to draw the item by default None

• pen (pyqtgraph.mkColor(), optional) – Arguments accepted by mkColor(), used to create the QPen instance used to draw the item by default None

• fillRule (QtCore.Qt.FillRule, optional) – FillRule to be applied to the underlying QPainterPath instance, by default QtCore.Qt.FillRule.OddEvenFill

Raises:

• ValueError – Raised when None is passed in as either curve1 or curve2

• TypeError – Raised when either curve1 or curve2 is not either PlotDataItem or PlotCurveItem

setBrush(*args, **kwds)

Change the fill brush. Accepts the same arguments as mkBrush()

setCurves(curve1, curve2)

Method to set the Curves to draw the FillBetweenItem between

Parameters:

• curve1 (PlotDataItem | PlotCurveItem) – Line to draw fill from

• curve2 (PlotDataItem | PlotCurveItem) – Line to draw fill to

Raises:

TypeError – Raised when input arguments are not either PlotDataItem or PlotCurveItem

setFillRule(fillRule=FillRule.OddEvenFill)

Set the underlying QPainterPath to the specified FillRule

This can be useful for allowing in the filling of voids.

Parameters:

fillRule (QtCore.Qt.FillRule) – A member of the FillRule enum

setPen(*args, **kwds)

Change the fill pen. Accepts the same arguments as mkColor()
