Shift between axis frame and ticks / image about wcsaxes HOT 5 CLOSED

I had a similar issue, I tracked it down to changeset 2a6f05e, lines 109-110 of frame.py:

if self._update_cache == [xmin, xmax, ymin, ymax]:
    return
self._update_cache = [xmin, xmax, ymin, ymax]
self._sample_cache = {}

If this logic is removed, then I get the correct behavior. @cdeil can you try verifying this for what you saw? @ChrisBeaumont any ideas?

Ah interesting, I wonder if this is an issue related to how figures are rendered into the notebook. I'll investigate

from wcsaxes.

@ChrisBeaumont - it looks like _sample_cache is never actually populated - is that normal?

Since this is obviously broken on the notebook, I think the short term solution is to drop the caching stuff (setting spine.data seems to have side effects, even when being set to the same value as before. But I can't figure out what they are).

@ChrisBeaumont Thanks for fixing this ... wcsaxes now works in the IPython notebook: http://nbviewer.ipython.org/gist/cdeil/36243e307090c7a740ba
