Is it possible to use a custom equation to fit the data in graph builder?

[#1]

Hi!

I've used graph builder to plot the data with grouped X (as shown in the attached image).  I wanted to fit all three curves using an exponential growth function. I only found Line of Fit and Smoother functions, but these are not what I would like to do.  I was wondering if it is possible to customize the fitting equation and also display the confidence interval of the fit as well as the statistics of the fit (e.g. R^2, F-test, equation) in the graph?

Thanks!

If you are creating the graph using JSL, it is a simple modification to delete the Axis Box() associated with the right hand axis.
Can you share the script that creates the graph?

Thanks. After some fiddling, I realized that de selecting the labels box in the axis setting did the trick as well.  Here is my graph and script
