how to avoid '_' interpretation in plot legend ?

[Sergei Steshenko-2]

Hello,

if I enter, say, the following command:

plot(1:10, 1:10, "-;foo_bar;1");

, I'm getting straight red line plotted (and this is expected), but the
legend says

foobar

with 'b' being below the rest of characters and having smaller size -
instead of the expected

foo_bar.


I think I should use some kind of 'set' command, but "help set" does not
provide particular info.


I know that for titles I should use

set(title("foo_bar"), "Interpreter", "none");

, but I do not know what to use for legends.

Thanks,
  Sergei.

Looks like a bug to me. I can't presently run the developers sources, but I see the same effect in 3.2.

The proper fix would be to properly implement the legend as a separate axes object, and have the text labels inherit their parent's interpreter property.

Until then it would be possible to (1) change the legend interpreter to "none", or (2) have the legend inherit the interpreter of its axes.

For a quick fix, and if you don't mind the console error it produces, you can try the change below

    plot(1:10, 1:10, "-;foo{_}bar;1");

How to change legend interpreter to none ? I.e. what is the exact command ?

Thanks,

Ben,

plot(1:10, 1:10, "-;foo{_}bar;1");

doesn't work, i.e. it produces (octave-3.0.3)

foobar

instead of the expected

foo_bar
.

Thanks,
  Sergei.

The legend does not presently have an interpreter property. The rendering of the legend appears to use be presently using the TeX interpreter. To change the behavior __go_draw_axes__.m would need to be patched to modify how gnuplot's keylabel is handled.

You are correct. I missed  the "missing" underscore.

Perhaps someone else can provide a solution?

Does strrep( mylegstr, "_", "\_" ) work or
   plot(1:10, 1:10, "-;foo\_bar;1");
?
I don't have an up-to-date copy of Octave to try, but its what I
normally use in the other brand.

the following workaround seems to work in 3.2.0:

octave-3.2.0:20> plot(1:10, 1:10, "-;;1");
octave-3.2.0:21> legend("foo\\_bar")

Yea, it also works with 3.0.3.
