how to get exacter plots Hi all,
I have a little problem with my 2D- gauss curves:
e.g. the curve
1522/(1.6*sqrt(2*pi))*exp(-0.5*((x-29.4)/1.6)**2)
shows not the expected rund shape on the top but a kind of flat base.
Other curves shifted small distances to the left or right show a kind of
peak instead the expeted nearly round shape on the very top.
Is there any parameter I can switch on to let gnuplot make some better
rendering on the curve?
Thank you!
cheers
Matthias

That's what happens if you don't have enough samples of the curve.
See 'help set samples' for what to do about that.
It also depends on the x range. Plot the above with
set xrange [25:33]
and you should get a rather reasonably shaped gaussian peak.
