How to color a single bar in a bar chart depending on a value from a different table?

I have a Bar chart on my mashup. That is showing few series of data. I want to change a color of a particular bar within a series in a bar chart, depending on a value that is stored in a different table. I tried to do some state formatting. But it is changing the color of the entire series. I just want to change only a particular bar's color. I am attaching an image for the reference.

Also is there any way to change color of bars from a service?

Thanks in advance.
