Plotting generates multiple pages

[Jonas Olson]

Hi!

Normally, plotting two curves in the same plot works fine, but when I
plot to a postcript file instead of to a window, the file ends up having
two pages, though I only want one. More specifically, I do this:

        x = [0:0.1:2*pi];
        y_1 = sin(x);
        y_2 = cos(x);
        gset term postscript
        gset output "output.ps"
        plot(x,y_1,x,y_2)

The first page of "output.ps" contains the plot I would have gotten if I
had run "plot(x,y_1)", and the second page contains the plot I really
want. Why does this happen?

Thanks in advance,
