Origin Version (Select Help-->About Origin): 7
Operating System: Windows

I wanted to draw a confidence interval of a regression line but lost on Origin and could not do that so could someone tell how to do it. I use origin 7.

Hi atindras:

If you want to plot the confidance band of linear regression, please referance to the help file

Curve Fitting>Linear Fitting Using the Tools>The Linear Fit Tool

section.

Or if in the case of nonlinear fitting, referance to

Curve Fitting>The Nonlinear Least Squares Fitter>Starting the Fitting>The Fitting Results

section.

Hope it helps!
