#1371 polar range not rotating, OS X 10.5.8 gnuplot 4.6.5 (macports)

[Anonymous]

"set trange [-90:270]" or "[90:450]" produces the same result as trange [0:360]
One might expect the range would get mapped to give a rotated output.
Often data with plan views have North, or 0 degrees at the top (e.g. antenna patterns). Perhaps there is already a correct way of achieving this & I have mossed it in the docs?

It works for me. These two plots are quite different:

set trange [-90:270]
set polar
set ang degree
plot t

set trange [0:360]
replot

To keep the same plot but rotate it you wouldn't want to change the sampling range, only the phase of the mapping:
set trange [lo:hi]
plot (t-phase)
