Thanks for the example. The problem was specific to the case where
multiprint was called after cross validation. It's now fixed in git.
Hi, let me stretch this thread some more, following up on this example
previously attached (multiprint_sven.inp).
If you add the call 'regls_coeff_plot(lb, X[1:10])' at the end you get a
nice plot as you should. Now, try to edit the plot (in the GUI), namely
to suppress the legend ("key" in gnuplot jargon). Nothing happens for
me. If I look at the saved gnuplot commands (before the edit attempt), I
see two suspicious lines:
set key outside
...
set key outside right noenhanced
And after the attempt to change it, it becomes:
set nokey
...
set key outside right noenhanced
It very much looks as if some internal hackery makes it impossible to
edit the plot in some ways.
The background is that I had a plot with many lines from regls, and the
legend took up 90% of the window area. Perhaps the underlying problem is
actually the relative space allocation (on Windows) between the plot
area and the outside legend area, don't know.
thanks
