I see how that would work if all of my Y axis were the same. Out of the 50
charts I'll use 10 different Y axis scales. How would I put the charts into
different groups to run the macro?

What you need to do then is write some formulas that determine reasonable
values for min, max, and major unit. Use these cells in the macro that
adjusts the chart.

I've used that technique on the X axis (time) and it works great however,
the
spreadsheet is being used as a template and I am putting in wide
variations
of data for the Y axis. I have been adjusting the y axis manually on 50
charts everytime I do another data run. For instance one of the charts
auto
scales 0 lbm/hr to 120,000 lbm/hr but all of the data is between 100,000
and
107,000. The next scenario I run the data is betwwen 40,000 and 46,000. So
I
need the charts to auto scale to 10 - 20 percent outside of the range
everytime I do a run.

I have a spread sheet with numerous charts. I need the y axis on the
charts
to set the minimum appoximately 20% below the lowest data point and set
the
maximum appoximately 20% above the highest data point. The major unit
should
be set at appoximately 10% of the entire range of data. The
spreadsheets
are
templates and will have a wide variety data placed into the cells.
