[OctDev] gnuplot zoom

[Stefan v. d. W. <st...@su...>]

Gnuplot allows the user to zoom in and out of a graph.  This, however,
only works while gnuplot is active.  I.e.:

$ gnuplot -persist
gnuplot> plot(sin(x))/x

I can zoom around happily.

gnuplot> exit

No more zooming.


I guess fixing it will require quite a few changes to gnuplot.  gzoom
works but requires the calculation of the axes prior to zooming.

An easyish-to-implement feature that gnuplot sorely misses is
plot-handles, i.e. a way to refer to a graph already drawn.

Is there anyone here with links to the gnuplot community that can make
a few suggestions to them?

Stefan
