Customize the color schemes and legend - Visual Report Builder

Also is there a way to customize the color schemes and the way that the chart lengend appears on the charts?

Unfortunately this is currently not possible with the Visual Report Builder.

In any case, I will submit a ticket to the Dev Team so that they can evaluate the possibility of implementing such feature. Unfortunately I cannot promise this feature will be implemented, nor can I provide an ETA for how long it will take to process this ticket. Nevertheless this is information the Dev Team should evaluate. Thank you.
