How to hide the value in heatmap?

I need to hide the value in the heatmap if it is zero.

Any suggestion?

You can ignore those values in heatmap by setting them to nan. For example,

M(M==0) = nan; % M is the name of your variable.
heatmap(M);

Thank you. But I dont think that's a good solution.

What is your expected output? Do you just want to make the 0 invisible?

[Zeynab Mousavikhamene]

Yes. I want zeros to be hidden.

[Ameer Hamza]

MATLAB does not support making individual labels invisible, but here is a workaround. You can set the text color to the same as the background color for boxes with 0 value. It that way, they will appear invisible.

M = rand(5);
M(M<0.5) = 0;

h = heatmap(M);
h.CellLabelColor = h.Colormap(1,:);

Thank you for your suggestion. I found a better way:

'MissingDataColor','1.00,1.00,1.00

Adding above code makes thos black circles white with no dat shown for NANs.
