Distance b/w Bar in Meeko Chart

[#1]

Dear Team,

I am using Mekko chart to display Region / Vendorwise Members count.

Problem which i am facing is the all region information is stuck together i want some space between all color boundaries.

You can use Bar Chart as below

Dimension

[RM Region]

Expression

Something similar to below... Change accordingly

SUM(Sales)/SUM(Total <[RM Region]> Sales)

But why we can not do so in this ? In the Application there i can see the sperator line in White but while PDF report its not showing.
