switch between key figures but keep same colors

Hi All,

i have a chart in which i have 5 different key figures. I have 5 different check boxes which either show or hide each of the one above. i have assigned colors as below. i used setDataSelection() to switch kFs

KF1: red

KF2:blue

KF3:green

KF4:orange

Kf5:grey

Issue: The chart colors are applied in the same order no matter what KFs are selected to display. For ex if i select to display KF3 and KF4 they are showing up with red and blue respectively instead of green and orange.

Please give me your inputs on how to configure the charts to avoid above situation.

Thanks,
