Re: [Matplotlib-users] Changing the hatch linewidth

[Thomas C. <tca...@gm...>]

I do not think the hatch linewith is currently controllable.

It is still hard coded
<https://github.com/matplotlib/matplotlib/blob/master/src/_backend_agg.h#L370>
in
the Agg backend.

Making sure we have a reasonable api to set the hatch linewidth and then
making sure it is well supported across all of our backends is a pretty
major task which is why I suspect it has not been done yet.

If you are interested in working on adding this feature, and improving
hatching in general, we would love the help!
