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.
