FillBetweenItem#

class pyqtgraph.FillBetweenItem(
curve1: PlotDataItem | PlotCurveItem,
curve2: PlotDataItem | PlotCurveItem,
brush=None,
pen=None,
fillRule: FillRule = 0,
)[source]#

GraphicsItem filling the space between two PlotDataItems.

__init__(
curve1: PlotDataItem | PlotCurveItem,
curve2: PlotDataItem | PlotCurveItem,
brush=None,
pen=None,
fillRule: FillRule = 0,
)[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 (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,
)[source]#

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

setCurves(
curve1: PlotDataItem | PlotCurveItem,
curve2: PlotDataItem | PlotCurveItem,
)[source]#

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 = 0,
)[source]#

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,
)[source]#

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