[Gnuplot-py-users] hardcopy of multiplot

[Marcus H. <M.H...@ls...>]

Dear all,

is there an (easy?) way to create a eps file of a multiplot-created plot?

I've created 3 three plot using the 'multiplot' option, and it looks quite nice
on the screen. But if I use the hardcopy() method on the gnuplot instance, the
resulting eps file only contains the output of the last plot() command, and all
the other plots are omitted.

I've also tried using the replot() command like

gp("set term postscript eps enhanced color")
gp("set output 'plot.eps'")
gp('replot')

, but this fails since all the temporary files that gnuplot.py creates are
already gone.

Any advice?

Cheers,
Marcus

As far as I'm aware, you need to set the terminal type and output  
before creating the plot:

g('set terminal postscript color enhanced "Helvetica" 18')
g('set output "'+filename+'"')
...
g('set multiplot')

and then make the plot as you normally would.  I close with

g("unset multiplot")
g.reset()
g('set terminal %s' % Gnuplot.GnuplotOpts.default_term)
g('set output')

though it isn't really necessary.

Gnuplot does not allow replotting (which is what hardcopy() does)  
when in multiplot mode, unfortunately (if this has changed in a very  
recent build, please let me know: I'm running 4.0).

If anyone else knows of a better method, I'd also be happy to hear of  
it.  Unfortunately, multiplot in Gnuplot can be a bit of a pain,  
particularly when trying to get several stacked plots to be the same  
size.

Good luck!
John

Hi John,

thanks, your method is working!
One has to run all the plotting commands twice, but that's not such a big deal...
