Stacked Barchart Custom colouring

[suresh_qv50]

Hi Experts,

We have stacked bar chart,

Having different dimensions with variable and nested if conditions,

Measures are

1. $(vAchApproved)/$(vTransactionCount)

2. $(vAchInsufficient)/$(vTransactionCount)

3. $(vAchNoAccount)/$(vTransactionCount)

4. $(vAchAccountClosed)/$(vTransactionCount)

5. $(vAchOthers)/$(vTransactionCount)

Like this we have 5 Expressions , we need to represent each expression with different values for Example

exp 1, RGB(0,255,0)

exp 2 RGB(250,0,0).........exp 5  rgb(0,0,0)

Please give me a solution how to achieve this.

Regards
