Marker types in 3d plots
Hi,
A few problems with marker types in 3D plots. I can use "o" and "^"
and "+". However I can not use "." or "," it seems a bit odd to me
however I get the below error. It should be possible to repeat this
with the following input
Traceback (most recent call last):
File "test.py", line 16, in <module>
