How do I change axes font (heatmap)?

Hello everyone,

I need to get a heatmap with all fonts being Times New Roman. I had no problems with heatmap values, more troubles with x axis font and I still can't change y axis font.

I am using this code:

h=heatmap(X, Y, C, 'FontName', 'Times New Roman');

h.xlabel('Something (unit)');

h.xlabel('FontName', 'Times New Roman');

h.ylabel('Something else (unit)');

h.ylabel('FontName', 'Times New Roman');

colormap(mymap)

And what I get is a heatmap with no y axis label. Everything else is alright. What am I missing here?

Your code is crashing at this line:

h.xlabel('FontName', 'Times New Roman');

The x label is set properly because of the previous line, and the y label is never set because the following line is never reached.

The x label has Times New Roman font because you specified that the heatmap's font should be Times New Roman when you called heatmap(). So this should work:

h=heatmap(X, Y, C, 'FontName', 'Times New Roman');
h.xlabel('Something (unit)');
h.ylabel('Something else (unit)');
colormap(mymap)

It worked, thank you.

But what do I do if I want to have axes label written in bold?

It doesn't work neither with:

h=heatmap(X, Y, C, 'FontName', 'Times New Roman', 'FontWeight', 'bold');

h.xlabel('something');

h.ylabel('something else');

colormap(mymap)

nor with:

h=heatmap(X, Y, C, 'FontName', 'Times New Roman');

h.xlabel('something', 'FontWeight', 'bold');

h.ylabel('something else', 'FontWeight', 'bold');

colormap(mymap)

Happy to help!

Heatmaps use the TeX text interpreter by default. To specify bolded text, put '\bf' before the text you would like to bold.

h=heatmap(X, Y, C, 'FontName', 'Times New Roman');
h.xlabel('\bf something');
h.ylabel('something \bf else');
colormap(mymap)

See here for general info about TeX.

That worked! Thank you very much :)
