Hi,
I have data that follows a logistic function. So I fit a logistic function through the data (and an equation is given). I would like to take the derivative of this function. Any suggestions on how to do it? Thanks! |

Origin can only numerically differentiate a dataset and then plot the resulting curve. To differentiate the fit curve make sure it is active and select Analysis> Calculus> Differentiate.
If you used the advanced fitter and don't see a fit curve click the fitter's More button (if you see it) and select Scripts> After Fit on the fitter's menu bar. Next, check the Generate Fit Curve option at the top and configure the curve. Finally, select Function> Save from the fitter's menu, repeat the fit and then differentiate the fit curve.
