create equal sized pie charts

Hi all,

we are trying to create 4 equally sized pie charts in a single row using SAIL and we followed two approaches

1. Create a Columns Layout and have 4 column layout in it

2. Create a Side by Side Layout and create 4 Side by Side Item in it.

In both the cases, we see that the charts doesn't appear in equal sizes, Further the size of the chart dependent on number of slices and labels that displays around it.

We also attempted to create empty columns/side by side items between the charts and we ended up with this

Here also its not equally sized. It seems there is no control over the size here. Is there a way to achieve this?

Thanks in advance,

Arjun.
