gnuplot: fragmented peaks on graph

Question

I'm plotting some data fitted with Gaussians, but the peaks aren't smooth, it gets better only if I zoom in enough on the peak.

the output code is: set terminal pngcairo size 1200,800 enhanced font 'Verdana,10'

And the resulted plot:

How can i smoothen the curves?

Thanks for your help!

Answer 1

Use set isosamples <N> where N is the number of points on your plotting domain, the default might be too low
