Heatmap doesn't show the values

Ran in:
The heatmap figures I used to plot on Matlab had the values labeled in each cell (just like the documenation says), but now the figure doesn't include the text. I'm not sure if I made changes to some settings. Does anyone know what the issue is?
For instance, I get the correct output here, when I run the following on web.
figure
heatmap(magic(5)); colormap(sky)
But this is what I get when I run this locally on my computer.
** EDIT: I run 2024a

Let's check that you're using the heatmap function included in MATLAB and not a different heatmap.m that you've written yourself or downloaded from somewhere else. What does this command show?
which -all heatmap
/MATLAB/toolbox/matlab/specgraph/heatmap.m /MATLAB/toolbox/matlab/bigdata/@tall/heatmap.m % tall method

Yup! You were right, I had a custom heatmap function stored in my main simulation folder. Thank you.
I can accept this if it's posted as an answer :)

I met the same problem. However, which -all heatmap showed that I have not other custom heatmap function in my path.What is weird on my computer is that when I zoom in, I can see the values in the cell. However, I cannot see them when clicking the "house" icon on the top-right to restore to default view. I am using R2024b.

I'm not able to reproduce this in R2024a myself either. You can assign the output of heatmap to a variable to access the heatmap properties though. CellLabelColor and ColorbarVisible are some properties to start with.

Hi @Taylor! The comment from @Steven Lord seemed to nudge me in the correct direction, and I think having a custom function changed the behaviour.
