Since XL will not let one link the scale parameters to cells (or named
formulas), you have to do this programmatically.

Bernard,

I'm trying to do something similar. Let me explain.

I would like the 100% point of the secondary axis match the maximum value on
the secondary axis. Let me give you an example.

I have a chart where the maximum plotted value for the primary axis is 9840.
The chart automatically sets the maximum for the primary axis to 12000.
I'd like the maximum for the secondary axis to be

12000/9840 = 1.22 ...

I suspect I'll need to do this programmatically.

I nave a named range of "TotalRequirements" and I need to get the maximum
value from that and set an upper level for the primary and secondary axis
based on that value.

How do I do this without any involvement by the user?

Thanks in advance,
Barb Reinhardt

What to you mean by 'equally spaced'
Same range (Max1=max2, Min1=Min2) ?
Same interval between gridline?

How do you space the primary and secondary axis equally. I've been
fooling
around with "Format Data SeriesOptions", but I can't get them equally
spaced
and with the same size. Is there something I'm missing or is Excel 2000
just
trying to intimidate me???? Connie
