3D plotting in mpl is unmaintained, so I don't recommend relying on it unless you can bring it up to date and maintain it.
After committing a bugfix to svn, the following works with svn mpl and does something like what you want (but might not work with whatever version of mpl you are using.) ---------------------------------- from pylab import * from matplotlib import axes3d N = 30 x = 0.9*rand(N) y = 0.9*rand(N) z = rand(N) c = rand(N) area = pi*(10 * rand(N))**2 # 0 to 10 point radiuses fig = gcf() ax3d = axes3d.Axes3D(fig) plt = fig.axes.append(ax3d) ax3d.scatter(x,y,z,s=area, marker='^', c=c) show() ----------------------------------------- A more general problem is that a 3D scatter plot is ambiguous--how do you know where a point really is in 3D? You would have to do something like mapping color to Z. Is that what you want to do? Eric william ratcliff wrote: > Is there a way to choose the color map for doing scatter plots using > Axes3D?
