[matplotlib-devel] Axes.scatter call fails since removal of PyCXX

2014-11-17 Thread Joel B. Mohler
I think I see a breakage of the scatter call that I think should work and did work before https://github.com/matplotlib/matplotlib/commit/be34210a8c09fcd639ece583eb5c0acb855222b6 This is running on windows 7 (32 bit) with numpy 1.8 and current master. The example is: *** import numpy from matplo
