Thread: [matplotlib-devel] 3D Axes scatter : no possibility to vary color/size of markers

Dear All,

I am trying to use the new 3D facilities offered by Matplotlib.
I know the mlab module of Mayavi, but I am interested in the vector 
export facilities offered by matplotlib.

Here is my issue : I can't manage to vary the color and/or size of the 
markers when doing 3D scatter plots :

fig = plt.figure()
ax = Axes3D(fig)
ax.scatter([1,2,3],[3,1,2],[1,2,0],c='r',s=[4,10,20])

The code above doesn't show size changes for each marker, just like :

ax.scatter([1,2,3],[3,1,2],[1,2,0])

Does anyone have an idea of what is going on ?

Thanks a lot,
luc

(I already posted this issue on the user list, but it seems to be a bug, 
and no one their seemed very interested in this  issue either...)

Hi

I have seen that there has been some mails asking about this problem
and it seems it was solved. Nevertheless, I am using the version
0.99.1 in windows and the problem still persists. Do I have any way to
apply a local patch?

Thanks,
Norberto

I got the same problem and posted my question in this forum 
http://www.developpez.net/forums/d836964/autres-langages/python-zope/calcul-scientifique/matplotlib-scatter3d-colorisation-fonction-z/
(here)  a few days ago... My question receives a lot of visits but no
reaction however I think it may be an important information for people
wanting to use matplotlib efficiently. Please let me know if you can find
anything about it :confused: Even if everything works perfect with 2D
scatter I can't solve this issue with scatter3D. Knowing that's it's a bug
should already be a nice answer...

Hi,

Thanks for reporting this bug, I fixed it in svn. In the maintenance
branch as well, so it will appear in next releases.

Regards,
Reinier
