Gaussian curve fitting in gnuplot manual

Ordinarily in peaks fitting each Fit Curve corresponds to one peak in experimental data. Click the Gaussian curve fitting in gnuplot manual button to add new Fit Curve to the list. There is a number of predefined Fit Curves types (Line, Parabola, Gauss, Lorentz, etc. ) You can also create a Custom Equation Fit Curve and manually enter the formula (Pro edition only).

Baseline fitting Oct 02, 2010 I'm trying to plot a Gaussian (bell) shape in gnuplot. I am using the function norm(x). The problem is that norm(x) plots just the first curve can better fit my data? Yes. But you really seem to be interested in statistical issues, rather than simply plotting. If you want to go further with this, you ought to Nov 13, 2013 This feature is not available right now.
