[Matplotlib-users] View just an angled part of an axis?

[Jody K. <jk...@uv...>]

Hi all,

I have some pcolormesh data that is in a thin strip along a slope at a (say) 45 degree angle.    Is there a way to set up a view of data just within dz of the slope, following the slope?  I would then stack successive views of this data.  

I tentatively tried something like:

pcm=pcolormesh(x,z,Ep,rasterized=True,cmap=jet,vmin=-13,vmax=-5)
rect = Rectangle((1,-8),10,4, facecolor="none", edgecolor="k",angle=-45)
gca().add_artist(rect)
pcm.set_clip_path(rect) 

But that doesn't clip properly.  

Note, I don't really want to rotate the data (that would be easy enough).  I'd still prefer there was the sense of a slope relative to the horizontal.  

Thanks for any thoughts...

Cheers,   Jody
