MATLAB: Changing the properties of a heatmap title

customizehandleheatmapheatmap titleMATLABtitle

For standard axes, the title property is a Text object, so properties such as Interpreter and FontSize can be setted directly.

However it seems that for heatmap objects, the title property is just a string.

Is there any way to modify the title properties? (for example setting the Interpreter to latex)

(The same applies also to XLabel and YLabel)

Matlab's heatmap() function (released 2017a) is notoriously difficult to customize. The handles to the title and axis labels are not accessible. You can follow the advice in this answer which shows how to overlay an invisible axes on top of the heatmap where you can customize the title and axis labels as you normally would.

Starting in MATLAB R2014b, the text objects used for graph titles and axis labels are no longer children of the axes. Instead, use the Title, XLabel, YLabel, and ZLabel properties of the axes to get the associated text objects.

For example, get the text objects used for the title and x-axis label.

ax = gca;
t = ax.Title;
xl = ax.XLabel;

Get the axis handle from the figure handle.

ax = gca(figureHandle);

Get the XAxis handle from the axis handle and set the FontSize of the x-axis only.

ax.XAxis.FontSize = 16;

or set the fontsize of the entire axis (x & y)

ax.FontSize = 14;

Set the XTick and XTick labels

ax.XTick = 1:4; 
ax.XTickLabel = {'A' 'B' 'C' 'D'};
