MATLAB: Subscript in stackedplot DisplayLabels

displaylabelsfigureinterpreterlabel;latexMATLABplotstackedplotsubscripttex

Hello everyone,
I'm trying to build a stacked plot with 3 graphs using Matlab 2018b's stackedplot-function. I'd like to write the corresponding DisplayLabels in TeX-style so that I can use subscripts, as can be done in regular plots without problem using e.g.
'T_{r}'
When I create a stackedplot using below code though, the labels are printed 'as is' instead of as a subscript:
s = stackedplot(f,If,'DisplayLabels',{'T_{r} = 50 ns','T_{r} = 20 ns','T_{r} = 10 ns'});

I've tried accessing Interpreter-properties and even setting
set(0,'defaultTextInterpreter','latex');
but couldn't get it to work as intended.
Can anyone please tell me how to do that?
Best regards
Sebastian

You can access the individual stacked-axes' properties via the hidden sub-property Axes of the stackedplot's AxesProperties property, and then modify the YLabel's Interpreter property to 'tex' or 'latex' (it's 'none' by default).
For example, to change the middle (2nd) YLabel:
s = stackedplot(...);
axesProps = struct(s.AxesProperties(2));  % using struct() is undocumented
axesProps.Axes.YLabel.Interpreter = 'tex';
Note that using struct() to access internal object properties is undocumented.
