Yes, you will want to use the scatter function for this. With "plot",
you can change the size of the symbols with the markersize keyword
argument, but all of the markers must be the same size. With scatter,
the individual marker size (and colors) can vary.
See
example code: http://matplotlib.sf.net/examples/scatter_demo.py

scatter help: http://matplotlib.sourceforge.net/matplotlib.matlab.html#-scatter
scatter support the following marker shapes (currently all regular
polygons)
's' : square
'o' : circle
'^' : triangle up
'>' : triangle right
'v' : triangle down
'<' : triangle left
'd' : diamond
'p' : pentagram
'h' : hexagon
'8' : octagon
Hope this helps,
