View just an angled part of an axis?

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:

rect = Rectangle((1,-8),10,4, facecolor="none", edgecolor="k",angle=-45)

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
