Hi Tim,
The control supports all valid SSRS expressions - we tested with a similar expression and it was working properly. Can you send and rdl file along with dummy data to test with?

I am looking to set the ranges in my standard bar chart to have custom ranges.  For example, I would like the "Begin" value to equal the minimum value in the dataset minus 2.  So my expression would look like "=(Min(Fields!PctChange.Value)-2)".  When I plug that into my expression, the range only sets to the minimum value of the dataset...it does not subtract 2 from the result.  Same thing on the ending value.  Has anyone tried anything like this before or have any recommendations?  Thanks!

Tim
