Is it possible to create a bubble chart with two series that share the same
X and Y values.  For example:

X    Y    values1   values2
10   11    300        0
14   20    150        0
20     5        0     100
30   30        0       40

I obviously haven't had any success <grin>.  I can create a bubble graph
with the x y and value1.  But I can't figureout how to get values2  with the
same x and y.  I can create an entirely seperate x y and values2 and add as
a new series, but my data is not constructed that way and it would be a pain
to re-arrange.

Thanks for any suggestions

Bob
