Hello ,
how can I anticipate the equation of the data which we plot in order to compare it with pre-defined equation we have for the same phenomenon

Hi a.hassanat89,

Not sure, but it seems you are talking about the curve fitting/regression among the Origin's data analysis features.

Here are tutorials:

Hope I understood your question correctly.

Hi Hideo Fujii ,
Thanks for your swift reply. Actually this is not what I meant.
what I mean is that I want to know the equation that governs my data values itself.
Does Origin has such a tool or gadget ?
thanks

Hi a.hassanat89,

Probably this "Fit and Rank Multiple Functions" feature is what you are looking for. (This is a "Pro" feature.)
