Change graph bar color for different category

Hi All,

Using PB12.5 here.

I have a graph which currently results as below and I would like to have different bar color for different category, kindly advise on how to do this.

Example:

Bar for "Pass" change to Blue.

Bar for "Fail To Safe" change to Yellow.

Bar for "Fail To Danger" change to Green.

Bar for "Total" change to Purple.

Fyi, I am using store procedure to create the graph and my graph 'Data' setting as below.

Thank you in advance.

BR,

Yow
