Axes.parametric(*args, values=None, cmap=None, norm=None, interp=0, **kwargs)[source]

Invoked when you pass the cmap keyword argument to plot. Draws a “colormap line”, i.e. a line whose color changes as a function of the parametric coordinate values. using the input colormap cmap.

This is actually a collection of lines, added as a LineCollection instance. See this matplotlib example.

  • *args ((y,) or (x,y)) – The coordinates. If x is not provided, it is inferred from y.

  • cmap (colormap spec, optional) – The colormap specifier, passed to Colormap.

  • values (list of float) – The parametric values used to map points on the line to colors in the colormap.

  • norm (normalizer spec, optional) – The normalizer, passed to Norm.

  • interp (int, optional) – If greater than 0, we interpolate to additional points between the values coordinates. The number corresponds to the number of additional color levels between the line joints and the halfway points between line joints.
