Boltzmann Fit

[peng wangParticipant]

I didn’t find the “Boltzmann Fit” function in the Fit Command, so I have to draw this graph in Origin through my office PC. I would like to know how to use this fit function in DataGraph. Hope I can use DataGraph to draw every graph I needed when I am doing scientific research.

通过fit function里面的Arbitrary，然后自己输入公式不能拟合吗？

DataGraph does not have a built-in function library for non-linear curve fitting.  You can add your own functions and create your own custom library.

Create a Function Library in DataGraph

This is using the Arbitrary Fit option of the Fit command as noted above.

Thank you so much! I have customized the Boltzmann Function in the Arbitrary Fit option to achieve nonlinear fitting.

Excellent!  Glad that worked!
