[matplotlib-devel] New patch (was: layering errorbars behind plot)

[Norbert N. <Nor...@gm...>]

Thanks for the reply. Surprises me that people would really argue about this 
issue, but well. :-)

Attached is a slighly changed patch: effectively, it does not change the 
layering any more, but it changes the internals of errorbar() in a way, that 
allows to swap the layering by simply swapping two blocks of code. (Which was 
nontrivial before, since the color from the plot line can only be read after 
it has been drawn.)

Whether this swapping is then done by hand, by an option or an entry in the rc 
file can be left to the future.

Maybe, submitting this patch will save someone else the time to figure it out 
himself.

Ciao,
Nobbi
