FillBetweenItem#

class pyqtgraph.FillBetweenItem( curve1: PlotDataItem | PlotCurveItem, curve2: PlotDataItem | PlotCurveItem, brush=None, pen=None, fillRule: FillRule = FillRule.OddEvenFill, )[source]#

GraphicsItem filling the space between two PlotDataItems.

__init__( curve1: PlotDataItem | PlotCurveItem, curve2: PlotDataItem | PlotCurveItem, brush=None, pen=None, fillRule: FillRule = FillRule.OddEvenFill, )[source]#

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 (color_like, optional) – Arguments accepted by mkBrush(), used to create the QBrush instance used to draw the item by default None
pen (color_like, optional) – Arguments accepted by mkColor(), used to create the QPen instance used to draw the item by default None
fillRule (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

Method to set the Curves to draw the FillBetweenItem between

Parameters:

Raises:

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

setFillRule( fillRule: FillRule = FillRule.OddEvenFill, )[source]#

Set the underlying QPainterPath to the specified FillRule

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