Re: [Gnuplot-info] how to draw Gaussian shape with histogram

[Thomas S. <t.s...@fz...>]

define the gauss-function,

gauss(x)=amplitude/(sigma*sqrt(2.*pi))*exp(-(x-position)**2/(2.*sigma**2))

fit it to the data, 

fit 'datafilename' gauss(x) via amplitude, position, sigma

and then plot it:

plot 'datafilename' with histeps, gauss(x)

and try to set 'amplitude', 'position', and 'sigma' to reasonable
values before fitting, otherwise the fit may get lost.
