Turn off TeX for legend labels

Rate this Message:
I have been able to set 'interpreter' to 'none' for titles and axes labels, but I can't seem to get it to work for legends. I would be grateful for advice. (I tried this on 3.0.1)

plot(X, Y, 'b','interpreter','none') Similar to Ivan's advice, this is stopping rendering of Greek, but I am still getting subscripts from underscores. |

Line objects do not have a "interpreter" property. Your example gives an error in Matlab, but does not in Octave. I'd assume Octave should give an error, but does not. Perhaps I'm confused. What objects do you expect this to impact? Ben _______________________________________________ Help-octave mailing list Help-octave@... https://www-old.cae.wisc.edu/mailman/listinfo/help-octave |

I am just trying stuff, to try and make it work. Let's say we have a plot with 3 curves on. you might want different settings for the legend labels for each curve. Indeed octave> get(get(gca,"children")(1)) shows you that the 'keylabel' and 'interpreter' for the legend are accessed via the plot handle. perhaps there is alternative workaround. Is there something like the HTML <pre> in TeX? |

The problem seems to be that while this is the correct way to disable tex rendering for legend entries in Octave, as Andy wrote in fact subscripts are still rendered (I can confirm that with development version), which is probably a bug.

I see your point. That is a bug, and it exists in the developers sources as well. In fact, I see the same behavior for text objects. >HTML <pre> means pre-formatted. Is there a way in TeX to stop TeX >interpretation of part of a string? In TeX, I'd use "\_". This does work for text objects, but it isn't working for me for the legend labels. Can you confirm the same behavior? Ben _______________________________________________ Help-octave mailing list Help-octave@... https://www-old.cae.wisc.edu/mailman/listinfo/help-octave |

If there are no | objections, I'll push it tomorrow. I think it would be much better to implement a Matlab-compatible legend function. I think doing that is possible now. The legend shouuld create an additional axes object that includes three objects for each entry in the legend. The first is for the marker associated with the legend item, the second is for the line, and the third is the label. I think placement and sizing will require some effort. It would also be nice if the legend object could be opaque so it may appear on top of other plot objects, but I don't think that is absolutely necessary. jwe _______________________________________________ Help-octave mailing list Help-octave@... https://www-old.cae.wisc.edu/mailman/listinfo/help-octave |
