Let's plot sin(100*x) without any option.
gnuplot> plot sin(100*x)

gnuplot> set samples 1000

gnuplot> plot sin(100*x)

gnuplot> plot sin(100*x)

For a 3D plot, use isosamples instead of samples. The default is 10, so let's try 50. (The detailed instruction for 3D plots will be given in the next section.)

gnuplot> set isosamples 50

gnuplot> splot [0:2*pi] [0:2*pi] sin(x)*cos(y)

gnuplot> splot [0:2*pi] [0:2*pi] sin(x)*cos(y)
