Is there any workaround available to show calculated values in charts

Hello All,

I understand that we don't have any direct option available to show data from 2 different Data Sources or calculated values from one DS (DS_1.Col1 + DS_1.Col2) on charts but do we have any workaround available or any SDK components to achieve the same. Any input is highly appreciated regarding this.

I am using Design Studio 1.5 and Business Objects 4.1 Universe.

Thanks & Regards,

Pooja
