Setting plot ranges

[Joe Koski]

In a recent exercise, because of some extreme "outliers," I needed to
override the vertical axis of a plot with gset yrange. I had been entering
this range "manually" e. g., gset yrange [0:10], but the scale varied from
plot to plot, so I decided to automate the process by calculating a maximum
that filtered out the extreme values.

It appears that you can't enter a real (or string) variable such as

Ymax = 2.0*mean(y);
S_Ymax = num2str(Ymax);

into the gset yrange [0:Ymax] or gset yrange [0:S_Ymax] command. Octave just
tells me that Ymax or S_Ymax are undefined.

Is there trick to doing this, or must plot ranges be entered only
numerically, without the use of variable names?

Thanks for the advice.
