Axes.parametric¶

Axes.parametric(x, y, values=None, cmap=None, norm=None, *, interp=0, scalex=True, scaley=True, **kwargs)[source]¶

Draw a line whose color changes as a function of the parametric coordinate values using the input colormap cmap. Invoked when you pass the cmap keyword argument to plot.

Parameters

*args ((y,), (x, y), or (x, y, values)) – The coordinates. If x is not provided, it is inferred from y. The parametric coordinate can be indicated as a third positional argument or with the values or levels keywords.
cmap (colormap spec, optional) – The colormap specifer, passed to the Colormap constructor.
cmap_kw (dict-like, optional) – Passed to Colormap.
norm (normalizer spec, optional) – The colormap normalizer, used to warp data before passing it to DiscreteNorm. This is passed to the Norm constructor.
norm_kw (dict-like, optional) – Passed to Norm.
extend ({{‘neither’, ‘min’, ‘max’, ‘both’}}, optional) – Whether to assign unique colors to out-of-bounds data and draw “extensions” (triangles, by default) on the colorbar.
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.
scalex, scaley (bool, optional) – Whether the view limits are adapted to the data limits. The values are passed on to autoscale_view.

Other Parameters

**kwargs – Valid LineCollection properties.

Returns

LineCollection – The parametric line. See this matplotlib example.
