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 matplotlib.backends.backend_agg import FigureCanvasAgg as FigureCanvas
from matplotlib.figure import Figure
POINTS = 500
figure = Figure(figsize=(6, 6), dpi=72)
ax = figure.add_subplot(1, 1, 1, projection=None)
scat = ax.scatter(numpy.arange(POINTS), numpy.sin(numpy.arange(POINTS)))
***
I get on current master
***
Traceback (most recent call last):
File "C:\work\mpl_scatter_example.py", line 9, in <module>
scat = ax.scatter(numpy.arange(POINTS), numpy.sin(numpy.arange(POINTS)))
File "C:\Python27\lib\site-packages\matplotlib\axes\_axes.py", line 3690, in

File "C:\Python27\lib\site-packages\matplotlib\path.py", line 977, in
get_path_collection_extents
master_transform, paths, transforms, offsets,offset_transform))
ValueError: object too deep for desired array
***
I did very little troubleshooting beyond confirming that this works before the
merge mentioned in the first paragraph.
