scroll issue on the pie chart

[#1]

Hi,

I have 1 dimension and 3 expressions on this pie chart and dimension and expression are both presented in scrolls. On upper right corner, description on dimension is displayed, but expressions on bottom left does not display the description. It works fine, but users need to click scroll to identify which expression is used on the chart.

I also remember hearing from a friend that if scrolls are in green, I need to fix something. I just can't remember what it was. Any ideas?

Thank you!

Ryan
