In this video tutorial, we will learn how to perform curve fitting with a polynomial function in OriginLab. We will start with importing the data into OriginLab and then proceed to perform curve fitting with a polynomial function using easy and simple steps. We will also learn how to customize the plot and the legend to make it more informative and visually appealing. This tutorial is designed for beginners who want to learn data analysis and visualization with OriginLab.

Learn alots of thing regarding linear fit sir plz also do it for band gap DRS data and IV plotting

[HunterHunter]

Thank You very Much. the masking was very important, thats what i was missing to fit both linear and polinomial fits in one single graph

[arsalanadil]

Linear and non linear fitting is very interesting. I like it, Thanks alots sir

Sir, how many values we can exclude so that R square values came in the range?

[umarfarooq-gspf]

Assalam o Alaikum Sir, very informative lecture.
Sir, I have to ask a question. I have got a polynomial fit that has "Adj R-square = 0.07943 and R square code is 0.59086". Sir if I exclude one or two values of data wouldn't it change the whole results. I mean the fitted curve would not be 100% real.

if R-Square is not 0.99 what can i do??? My fitting doies not show this standard values

[fawadahmad]

great Sir. Sir but why we do fitting and what is mean by R square value?
