The other post points out that the point size applies to all points in a
plot, and it has only a few possible sizes.
The better solution is probably to look at the picture example for XY
graphs. You can then open up the diagram and look at the source code
for it. You will find a loop that draws for each point. You might also
want to look at the scatter plot example.
