the same thing with alpha values?
You can use a colormap with varying alpha values.
Would it be possible to do something like
ax.plot(x, y, color=[c1, c2, c3], alpha=[a1, a2, a3])?
It doesn't seem that it's supported and that would be the 'natural'
extension, in some sense.

alternative gallery page. The figures you linked look shinny but not much

Point taken on the context argument. I'll take that. To resolve it,
