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,

MatPlotLib question: How to get more different size plot symbols in
the plot function ?

Is there a way to get different size squares (or circles or triangles,
etc.) ?

For example, in a two dimensional plot of heights and weights of
individuals, is there a way to represent also the age of the
individual by the size of the plot symbol ?

Thanks for your help.
