Unable to change colour for chart columns

[RavindraMurthy]

Namaste,

I created a chart for Plan Vs Actual in row series, there are 2 columns, i want Plan and actual to be in 2 different colours, but not able to customize colours.

If change chart type to column series i can customize colours but x-axis legends gets changed, which is not correct, i want to retain the x-axis legends as in row series.
