Hi All,
I have upgraded matplotlib from an old version I was using
(0.91.2) to the very latest one (0.98.1). In one of my applications, I
am using this code:
from matplotlib.transforms import offset_copy
def offset(ax, x, y):
return offset_copy(ax.transData, x=x, y=y, units='dots')
Right now I get:
Traceback (most recent call last):
File "E:\MyProjects\SimKill\SimKill.py", line 9, in <module>
from PlotPage import PlotPage
File "E:\MyProjects\SimKill\PlotPage.py", line 11, in <module>
from matplotlib.transforms import offset_copy
ImportError: cannot import name offset_copy
Is offset_copy gone? How can I modify my code to get back the original
behaviour?
Thank you for your suggestions.
Andrea.

Yes, this is one of the casualties of the transforms refactoring in 0.98. The new transformation framework is documented here:
http://matplotlib.sourceforge.net/doc/html/devel/transformations.html
Most of the changes from 0.91 to 0.98 are documented here:
...but it seems offset_copy was overlooked (probably because no code internal to matplotlib was using it.)
You can do something like this to simulate offset_copy:
return ax.transData + transforms.Affine2D().translate(x, y)
Let me know if that works in your context. If not, I'm glad to help.
Cheers,
Mike
