It sound like you are saying that each graph in a series is not the same size; correct? This is an interesting problem that I haven't seen before. I'm unclear from your message if you are creating a series of pie charts or a series of bar charts. Can you clarify?
Correct. I found that each pie graph in a series is not the same size !
and sorry for my mistake, I use 'balance_amt' for Segment Size, 'Customer Class' for Segment and 'month' for Horizontal Matrix.
In addition, I use WRS 3.1.
The Fixed Size in the graph properties only specifies what the size of the entire graph object on screen will occupy in pixels. It has no bearings on the individual size of pies in a graph matrix (when multiple pies are being shown).
The only way that the pies can be made the same size in a graph matrix when a series is supplied is if you turn OFF data value labels on the pie through the property dialog. If they are left ON then the pies in each cell of the graph matrix will scale differently depending on how many or where the data value labels are placed inside each cell.
Will it meet your needs to turn off the data value labels? Perhaps we can consider including a property for keeping the pies the same size even when the data value labels are displayed.
