Thread Subject: plot function

Hello,
is it possible to have a plot with 2 scales on the x axis corresponding to the same value on the y axis?
Thanks
Daniele

Matlab does not provide any function to do that. *Possibly* you could use plotyy()
to plot two different y axis against the same x, then use a hggroup() and hgrotate() to
rotate the view of the graph to its side...

But it if were me, I would check out the FEX contribution plt() to see whether perhaps
the possibility you want is one of the many options that are already built-in to
that contribution.

relationships -- what if we scrambled your data or used -Inf, NaN, or complex(rand,rand)?

Hi Daniele. As Walter mentioned, it is likely that "plt" can be used to create
the plot you are need, although to be sure, you might have to be more clear
about what you need.

If you just want an alternate x-axis showing the same thing as the primary
x axis except using different units, that is pretty easy. In the plt distribution,
take a look at the example "demo\tasplt.m". Note that the lower x-axis has
the units "gph" and the upper x-axis has the units "percent power". In that
example, the two units are the same except for a scale factor difference, so
it is trivial to implement as you can see from the code.
