Is there a way to change the sizes of scatter plot markers for mplot3d.Axes3D.scatter3d ? I do from mpl_toolkits.mplot3d import Axes3D ax = Axes3D(gcf()) x,y,z = randn(3,20) ax.scatter(x,y,z,s=30*rand(20)) and I expect to see 20 points of a range of sizes from 1 to 30... but instead I see them all the same size. How can I set the size of the markers? |

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) On Mon, Jan 18, 2010 at 11:49 PM, Matthias Michler <Mat...@gm...> wrote: > Hi Erik, > > with current svn I see markers of different size.
