Legend colour change after filtering

Legend colour change after filtering

Hey

I have recently started using zoho reports and I made a dashboard that uses user filters to change the values for all the charts within it (very cool by the way). My problem is that when I filter using the user filters the colours of the legends change. I really need some help with this since I need the colours to remain the same even after filtering. Is this possible and how can i implement this?

Thanks in advance
