Re: [Matplotlib-users] mplot3d scatter3d marker sizes?

[Erik T. <eri...@gm...>]

Apparently it wasn't recent enough - I updated to the latest svn and
now they are sizing properly - thanks!

Another oddity I've noticed, though - if I do

ax.scatter3D(x,y,z,s=30*rand(20),c=rand(20))

I would expect to see the points colored based on a color map for the
supplied scalar values.  Instead, they all appear white.  If I do
rand(20,3) , it gives random colors, but that's specifying r,g,b
values instead of scalar mapping.  Is there a way to do the color
mapping directly as in the 2D scatter? (If not, it's of course
possible to manually apply the mapping - just less convinient)
