- class pyqtgraph.CurvePoint(curve, index=0, pos=None, rotate=True)[source]#
A GraphicsItem that sets its location to a point on a PlotCurveItem. Also rotates to be tangent to the curve. The position along the curve is a Qt property, and thus can be easily animated.
Note: This class does not display anything; see CurveArrow for an applied example
