Re: [Gnuplot-bugs] Bug?

[Tatsuro M. <tma...@ya...>]

Hello

Please read the help for sampling points for function by

gnuplot> help samples

Default samplig points is 100.

It is natural that the graph of pl [0:100] sin(x) is strange.
Please change the sampling  number by 'set sample ......'

Regards

Tatsuro
