How to add subscript in labels in App Designer Matlab

Hey, I want to add subscript/superscript in label text. Being new in the community, kindly help as I don't know much.

Shankar,

I would not consider may recommendation as an answer. However, until MathWorks adds all text elements to 'tex' and 'latex' interpreters for App Designer labels, I have been stacking labels to create the appearance of subscript and/or superscript text in my labels.

My primary label with spacing included:

My stacked labels. I reduced the font size for the labels displaying "min" and "max", then placed them over my primarly labels.

Hopefully this techinique or something similar will suffice until the interpreters can handle sub- and superscripts.

App designer does not yet support an interpreter in all text elements. This post contains details on which elements supported the 'tex' and 'latex' interpreters as of 18a.

Is this updated in 2019B?

[Cris LaPierre]

It is not. You can see the available label properties here.

[Chris Calhoun]

Do you have any idea when it'll be updated?

[Cris LaPierre]

Sorry, but I do not.

It is strange that GUIDE supports subscript for checkbox, while App Designer does not.

[Cris LaPierre]

You could remove/leave blank the label associated with the checkbox, and use the Label component to create a label that does support subscript.

@Cris LaPierre Using label to fake a sucscripted text is an awkward solution. For checkbox, you can click the text to make the checkbox checked, in addition to click the box itself. However, if you use label to fake the text, the only option is to click the box itself. This inconsistent user experience between different checkboxes would apparently make the user confused. Not to mention how difficult it might be to locate a small box in a large UI.

That is the nature of workarounds.

Select html for Text Interpretor, then in your startFcn, add the following text:

app.TextFieldname.Text = ['Lower Freq (_min)'];

Where TextFieldName is the name of the text field you are triyng to change.

I am not sure what version it was introduced, but R2023b now includes an interpreter property for labels in App Designer.

Use the link below for information on how to use interpreters.

In R2021a. You can see that in the Version History section of the Label Properties doc page.

Thanks Allen. I discovered however does the font looks awful and can't be changed.
