How to change text interpreter of HeatmapChart?

66 views (last 30 days)
The HeatmapChart() object takes over control of the XLabel, YLabel, Title, and TickLabels seemingly without letting you change the text interpreter. Is there an undocumented workaround or am I missing something?
h = heatmap([1 3 5; 2 4 6]);
h.Title = 'My Heatmap Title';
set( findall( gca,'-property','Interpreter' ),'Interpreter', 'Latex' ) % doesn't help
set( findall( gcf,'-property','Interpreter' ),'Interpreter', 'Latex' ) % doesn't help
set( groot, 'defaultAxesTickLabelInterpreter', 'LaTeX' ) % doesn't help

h = heatmap([1 3 5; 2 4 6]);
h.Title = '$x^y$';
h.NodeChildren(3).XAxis.TickLabelInterpreter = 'latex';
h.NodeChildren(3).YAxis.TickLabelInterpreter = 'latex';
h.NodeChildren(3).Title.Interpreter = 'latex';

No, there does not appear to be any way to do that. Some of the details are hidden inside a .p so I cannot be absolutely certain, but all of the code I have found so far requires that the data be numeric.
