How to fit data to log function?

[kbaker]

I have some xy data that I would like to fit to a log function so I can determine the log equation i.e y=a*log(x).  I believe I need something similier to the exponential fit VI?  Thanks in advance.

Use the "Curve fitting" express VI, select "non-linear" fot the model type and enter your equation into the model field and give it some reasonable initial estimates for the parameters. Try it! 😄
