NaN value in data tip causes error

I am using dataTipTextRow to create custom data tips for my plot. I have found that when there is a NaN value in the Value field, I get an error when I click on the associated marker in the plot. Instead of my custom data tip I get the following text in a box:

Error unable to convert 'string' value to 'char'

The other points in the same plot object are able to display their data tips properly. I haven't figured out a way to determine exactly which line of code this error is happening on. Any ideas on how to fix this?

Hi David,

I tried to reproduce the issue in MATLAB R2023a with the following code and it worked just fine with all the datatips, even the ones with value=nan shown correctly.

x = 1:10;
y = rand(1, 10);
values = ["a","b",nan,"d","e","f","g","h","i","j"];
s=scatter(x, y, 'filled');
row = dataTipTextRow('label',values);
s.DataTipTemplate.DataTipRows(end+1) = row;

If the issue is still persistent, please share your code and the MATLAB version in which you are facing the error.

works fine even with the older R2020b
