GGRAPH SCATTER

[Ben W.]

I am trying to get a a 2-d chart with multiple categorical layers
using a scatter in GGRAPH. What
I'd like is to get a shape and color for group 1 (e.g. blue ovals).
a different shape and
color for group two (e.g Orange squares). This is easy - its x-y by
color variable. The next part. different fill
pattern based on a fourth variable variable (E.G. fill in only certain
points) - blue with blue -- orange with orange). Every time I try
this GGRAPH fills in all the variables or changes the color of the
some other pattern.

Any suggestions?

Can i multiply the categorical in the element statement so transparency
(gen*loc)? I just thought of this. not sure it will work

For example

y=Salary
x= years of service
gen = men/women
loc = U.S/overseas

Grapsh of salary $ by years of service for men and women. men colored
blue and shape squares; women orange and shapes ovals. Hard step -
fill-in blue circles with blue for men overseas - fill in women
squares with orange for women for overseas
