Multiple Color combination for Text Field in Charts

Multiple Color combination for Text Field in Charts

Hi All,

I have a Report that has a "Text" Field [In Edit Design] values as "Billable" and "Non-Billable". 

My other fields such as X-Axis, Y-Axis, Color, and Size is already filled. 

My problem is I am getting the below Chart with both "Billable" and Non-Billable" in the same color demarked by only a LINE as given below:

Does ZOHO has the ability to apply multiple colors for the same "Text" Field? 

I want different colors for "Billable" and "Non-Billable" demarked by a LINE.

Please see the attachment below.

Thanks,
Vikram
