Multicolored Graph

[#1]

Hi,

I have a bar chart which shows data for a week (sun to sat) according to the input date by user which also works as a reference line.

when i create this graph as multicolored, the color changes for each data point.

Is it possible to create this chart as dual colored such that color of bars before ref line is same and color after theref line is diffrent.

Thanks

Aaditya
