Datatips in standalone apps do not work in Matlab 2019b

I am developing an standalone app, where I want to show data tips in every plot to improve plot readibility. My experience is that this is working normally as long as I run the app from App Designer or within Matlab. However, as soon as I compile the app (I have Matlab 2019b) to create a desktop standalone app, the data tips are not shown anymore. This is true also for standard data tips, that is without customizing them dataTipTextRow.

To help solving my problem, I have created a very simple app to see if I make any mistake. This simple app is plotting the sine function between 0 and 2*pi().

Thanks in advance for any help, Alessandro

Answer 1

[Jacopo Remondina]

Any news about this issue? Is there a bug tracking code to follow?

I'm still experiencing it in matlab 2020b update 1, but with some differences:

1. the black dot always display;
2. The message window (customized) sometimes is displayed, and sometimes not;
3. The problem happen both while using matlab itself and when the app is compiled

Notes:

GUI elements are all of the ui family, but I created them programmatically and not using appdesigner

Perhaps the problem is related to the fact that I have a tab group with a uiaxes in each tab (the last one is the one that work better and most of the times)

The custom function for generating the datatip text is fully executed (tested with console output)

Hi Alessandro,

We are aware about this limitation and this feature may be supported in future releases.

Thanks,

Nidhi Mittal

[Benjamin Holter]

will 2021a support these?

[Maximilian Gaukler]

Standard data tips (mouse click into any plot) work fine in an app compiled with R2021a.

[Nicolangelo Piscitelli]

In Matlab2023a, no data tip is shown on scatter plots (compiled application). Is this a known issue?
