Hi Achan87,
According to your description, you need to adjust the distance between the slices in your Exploded Pie Chart, right?
Based on my research, the distance changed based on the size of chart automatically. And we cannot adjust the distance between the slices in current version of Reporting Services.
If you have any concern about this feature, you can submit a feedback at
http://connect.microsoft.com/SQLServer/Feedback and hope it is resolved in the next release of service pack or product. Your feedback enables Microsoft to make software and services the best that they can be, Microsoft might consider to add this feature
in the following release after official confirmation.
Thank you for your understanding.
Regards,
