Re: [matplotlib-devel] New backend API [Was: bugs found]

[Darren D. <dd...@co...>]

I think I actually got the new api working with draw_markers and draw_lines in 
backend_ps. The transforms are done by passing the results of 
transform.as_vec6_val to postscript. I would appreciate it if someone would 
test it out and give me feedback. In order to do so, update from svn and 
unmask backend_ps.RendererPS._draw_markers (not _draw_markers_old) by 
removing the leading underscore. Try plotting things like

plot([0,1,2,3,4],'-o'); savefig('linear.eps')
plot([0,1,nan,3,4],'-o'); savefig('linear_nan.eps') # Not possible with the 
old API
semilogy([0,1,2,3,4],'-o'); savefig('nonlinear.eps')
semilogy([0,1,nan,3,4],'-o'); savefig('nonlinear_nan.eps') # Not possible with 
the old API

Are there other methods that need to be updated to use the new API? There are 
a bunch of unused methods in RendererPS that I will clean up once things have 
settled, please ignore them for now.
