Overlapping Series in Range Charts in SSRS

Hi,

I have a Range Chart as shown as shown below. I am trying to highlight the category group in any way possible.

One solution is explained in the blog "Overlapping Charts in SSRS using Range Charts"

http://road-blogs.blogspot.com/2012/03/overlapping-charts-in-ssrs-using-range.html

But this is for bar chart. I have a range chart, can we implement similar solution for Range Charts?

If not, is there any otherway we can highlight the category group?

Thanks

NC
