I have a sheet in a Workbook that holds about 21 charts. When I add data to
the workbook, I need to go into every chart and add rows to each data series
as well as the Horizontal Axis. Since this is tedious, I wrote a Macro to do
this. The Macro works great...but when I run it, any chart that is off-screen
disappears. It still exists, but the only way I can make it visible again is
to save the workbook, close it, and reopen it. I have tried to refresh the
graphs as I update them, but that hasn't fixed it.

The only fix that I have found that works is to temporarily set the Window
zoom to 10% so all the graphs are visible, update the chart ranges, then
reset the Window to the value it was when the Macro ran.

Any idea why the off-screen charts are disappearing? Any suggestions on
eliminating this issue? I'd rather run the Macro w/ ScreenUpdating off so it
will run a bit faster w/out the user seeing the zoom resets, but that defeats
the purpose.

If necessary, I can post the code.

Thanks,
Paul
