[Matplotlib-users] how to use transforms to rotate and shift a group of objects

[Dr. J. Z. <joh...@ze...>]

Hi,

I'd like to plot several objects which are defined in coordinate systems 
which are local to each object in a common plot.
The objects (and the corresponding local coordinate systems) are rotated 
and translated wrt. a global reference point.

I tried something like

r = matplotlib.transforms.Affine2D().rotate_deg(90)
matplotlib.pyplot.plot(x, y, transform = r)

but this didn't work.

Additionally to matplotlib.pyplot.plot I use also 
matplotlib.patches.PathPatch, matplotlib.pyplot.plot to draw shapes and 
text.

Any help on how to rotate (and shift) a whole assembly which contains 
eg. a matplotlib.patches.PathPatch and an annotation would be helpful.

regards,
