How to set AllowEmpty in numeric uieditfield to 'on'

Hi, I've been trying to set a placeholder on a numeric uieditfield and been unsuccessful.

According to the documentation here, I should be able to run the following code:

fig=uifigure
xlim=uieditfield(fig, 'numeric');
xlim.AllowEmpty = 'on';
xlim.Value = [];
xlim.Placeholder = 'Input x axis limits';

But this error message appears:

Unrecognized property 'AllowEmpty' for class 'matlab.ui.control.NumericEditField'.

Which is really confusing because the documentation clearly lists that as a property.

Any help is greatly appreciated. Thanks you very much.

Your code seems to work just fine; when I run it I get no error message and I get an edit field with your specified placeholder text displayed in it.

I would, however, recommend changing the name of your edit field handle variable to something other than xlim. That is a commonly used Matlab function (for changing the x axis limits of a plot).

Running OP's code in R2022a, I get the same error message OP reports.

Hi all, as T.Nikhil pointed out in the other thread, it may be a feature for newer versions but I'm stuck on R2022b at my company. Thanks for the help!

Hello Angus,

I understand that you want to create a placeholder for your numeric edit field but are facing errors with it.

These features of creating a placeholder by leveraging the ‘Placeholder’ property and of allowing empty edit field using the ‘AllowEmpty’ property are additions to the latest release of MATLAB i.e R2023b. Hence, you are facing this error since these properties cannot be accessed in earlier releases.

I would suggest you update your version of MATLAB to R2023b to be able to use these properties.

Hope this helps!
