Here's one way to do it:
#!/usr/bin/env python
import matplotlib
from matplotlib.patches import Circle
import pylab
def myscatter(ax, colormap, x, y, radii, colors):
for x1,y1,r,c in zip(x, y, radii, colormap(colors)):
ax.add_patch(Circle((x1,y1), r, fc=c))
fig=pylab.figure()
ax=fig.add_subplot(111)
myscatter(ax, matplotlib.cm.jet,
pylab.rand(20), pylab.rand(20), 0.1*pylab.rand(20), pylab.rand(20))
ax.axis('equal')
pylab.show()
Implementing a CircleCollection as a subclass of PatchCollection would
probably lead to a faster solution, but perhaps the code above is enough
for simple needs.
