Converting performance tables to performance curve [closed]

edit

Hi, I have data in form of performance table with two independent variables. I want to create a performance curve based on this data. Has anyone have experience in this regard?

The data (performance table data) is extracted from a Table:Lookup in EnergyPlus. But I want to convert it to a performance curve to be able to use it in CBECC. The reason for this conversion is that performance tables cannot be input in CBECC.
