Is it possible to make a custom data cursor function in the app builder? I've tried to do it with:

dcm_obj = datacursormode(app.UIAxes)

but that just threw an error instead. Is it even possible to do this in app builder right now?

It have gotten it to work but not to create a custom data tip function. Ii also looks like you are passing it the axes handle not the figure handle. The below code works but when I click my axes to get a custom data tip using myupdatefcn I get "Unable to Update data tip using custom update function".

dcm_obj=datacursormode(app.figHandle);

dcm_obj.Enable='On';

dcm_obj.UpdateFcn=@myupdatefcn;
