performance tables to curves

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?

Please tag it with the software you're using. If EnergyPlus, can't you use a Table:Lookup object?

Thanks for pointing this out. The data (performance table data) is extracted from a Table:Lookup object in EnergyPlus. But I want to convert it to a performance curve to be able to use it in CBECC (California Energy Compliance Software). The reason for this conversion is that performance tables cannot be input in CBECC but performance curves can be input in CBECC.

You need to perform Curve fitting then. Have you looked at the "CurveFitTool.xlsm" that is installed with EnergyPlus?

It's inside EnergyPlus-23-1-0/PreProcess/HVACCurveFitTool.
