parallelplot and latex interpreter

I am using parallelplot to generate some plots. However, when I used:

set(gca,'TickLabelInterpreter','latex');

I get:

Unrecognized property TickLabelInterpreter for class ParallelCoordinatesPlot.

Is there any alternative to set the x and y labels of my plot to latex style?

Example:

data = randi(1,10,3);
p = parallelplot(data)
p.CoordinateTickLabels = {'one','two','three'};
set(p,'TickLabelInterpreter','latex');

This solution isn't ideal and doesn't direclty address your goal.

If you're using MATLAB R2022a or later, you could use the fontname function to set the font for the entire figure generated by parallelplot, not just the tick labels. You'll also need the font used by latex (see How can I add a new font).

@Adam Danz thanks, seesm it is the only option. What I am not sure which font resembles the one nomrally a latex interpreter wpuld use, crm8, msam8, cmss10, cmr10?

[Adam Danz]

Good question. I found this answer that points to cmr12 but I haven't tried it. You can also add fonts to your system that should show up in MATLAB. See the listfonts list after a MATLAB restart.

@Adam Danz, Hi, I try to use the answer of @LR_eng, converting the parallel plot into a struct variable. It works for the XTickLabel, but then when I try to save the figure it go back to the previous ticks. You suggested here to use:

S.AutoListeners__{1}.Enabled = false

However, even using it, the figure go backs to the previous ticks. May you have any suggestion? Thanks in advance for your time.

Hi @Rub Ron,

I wrote that solution prior to working at MathWorks. It uses undocumented features that aren't intended to be use-facing. The problem with using undocumented features is that they may not behave as one may expect and there is no guarantee that they will be supported in the future. We will consider adding an intepreter property that can be used with parallelplot.

I just had the same problem. Just changing the font did not help me. Apparently, one workaround is to convert the parallelplot object to a struct like it was done here. This worked for me and that way you can also nicely access all the other useful properties. However, it produces a warning that it is not recommended to do it like that.

data = randi(1,10,3);
p = parallelplot(data);
S=struct(p);

Warning: Calling STRUCT on an object prevents the object from hiding its implementation details and should thus be avoided. Use DISP or DISPLAY to see the visible public details of an object. See 'help struct' for more information.

S.Axes.TickLabelInterpreter='latex';
S.Axes.XTickLabel = {'$1^1$','$2\cdot2$','$\sqrt{3}$'};

Hi, I tried and it worked but only for the ticklabels, but the rest dont change the style to latex. For the rest I tried: S.Axes.TextInterpreter='latex'; S.Axes.LegendInterpreter='latex';

[LR_eng]

Sorry I did not see that you also need the ticks on the y axis. Maybe you can try the following:

S.YRulers(1).TickLabelInterpreter='latex'
S.YRulers(2).TickLabelInterpreter='latex'
S.YRulers(3).TickLabelInterpreter='latex'

[Rub Ron]

Thanks, but still, what about the x and y labels and the legend

If you are using this approach, just be aware that it is undocumented and not all aspects are guaranteed to work. I've added some additional context over on this other question on the topic, but one huge caveat is that any changes you make to the axes directly won't survive save/load and are unlikely to work in the Live Editor.
