Re: [Gnuplot-info] another syntax problem

There isn't any rounding going on, it is just that your function is
spanning a very narrow y range so you need to increase the precision
of the y-axis labels for them to be meaningful.

    set format y "%.8f"

will get you into the right space, then see

    help set format

I don't think that

     set zero 1e-20

Is doing anything for you.

Best,
