I need to create 3 pie charts that are same size . . .
 

I need to create 3 pie charts w/ legends to all be the same size, but
the fact that each pie chart has different amounts of data (3, 5 and
6) the pie chart gets smaller and smaller. On top of that, the pie
chart and legend seem to sitting in a drawing canvas of sorts, which
is OPAQUE and doesn't anchor down on the spreadsheet. How does one
control this wicked canvas?

All 3 of the pie charts have data in a column. However, 1 of them I
had to select the cells in the column to avoid the subtotals. But it
created a "Series 2" automatically. Why and could I delete this?

I would be extremely greatful for your constructive instruction and
suggestions.

Yours truly,
Paul
