have 8 signals versus time; would like to plot an overview of these signals; can do that with subplot command putting each signal in a single subplot
however would like to have optimal vertical signal resolution on the screen; subplot does not do this as regards the large non-used areas of the screen (for example upper and lower non-used ares).
Does anyone know a way to plot different signals with different vertical scales versus time in a single plot ?

Ready-made, there's plotyy() that would give you two axes so you could
selectively place series on the axis w/ the nearer range.

Alternatively, otomh two other choices --

1) Scale the signals to +/-N Std deviations and plot them that way --
linear transformation so relative shapes are same. I'm assuming don't
need the absolute values for this purpose

2) Draw multiple axes -- there's an example in the documentation on
specialized graphics of how

Oh, also you might check the code exchange and see if there's some
submittal that suits....

If you want to restrict the axis limits to the range of the data in
each subplot, use 'axis tight' in each one of them.
