Exponential Curve fit

[Naseemvp777]

Hi,

I am trying curve Fitting in Labview. The equation which I am using is y=a*exp(b^x).

I have only two co-ordinates and while using exponential fit.vi it fits d curve same as a linear fit.

Any help would be greatly appreciated.

Please find the attached vi and expected graph below

Thanks in advance

You only plot two points. To generate more points, generate a x-ramp with reasonable range and resolution and generate y data based on the best fit parameters.

Here's one way to do it.

Thanks a lot for the solution 🙂

Since you did not fit for the offset, I left it out for simplicity. For a more universal solution you might want to also add the offset when generating the simulated data, even though it is zero in this case. (Fewer changes needed if you ever need to include an offset in the future).

Also note that you can easily make the range for the simulation wider (e.g. 190...260) for a less cramped look.

Thanks a lot for the Suggestion. Will take care of Offset.
