Are annotations supported in uifigure objects?

Are annotations supported in uifigures created in AppDesigner?

Answer 1

[Jan]

I asked an internet search engine for "Matlab annotations appdesigner" and the first hit is https://www.mathworks.com/help/matlab/creating_guis/graphics-support-in-app-designer.html. Here you find:

 However, the following functionality is not supported:
 ...
 Annotations and Colormap Adjustments:    annotation

This sounds like annotations are not supported.

Although I really like this forum, I admit that Google took only 0.47 sec to find the link, while I typed for minutes to post, what was found automatically. Therefore it is recommended to search before asking.

Thanks, Jan. I'm getting all those errors too, which is what prompted my question. I guess what I really should have asked is if there's another similar feature that >does< work in uifigures. Or does Mathworks plan to add this functionality?

[Walter Roberson]

I suspect Mathworks does plan to add this, but I have no idea what their timeframe is.

Meanwhile the work-around is text() and line()

[Sean de Wolski]

or uilabel if you'd like text off the plot.

According to the updated documentation, annotation objects are supported in appdesigner (same link provided by Jan).

uif = uifigure(); 
x = [0.3 0.5];
y = [0.6 0.5];
annotation(uif,'arrow',x,y)

However, unlike regular figures, the annotation object does not appear on top of existing axes in UIFigures, at least not in r2020a.

Here's a demo that creates two figures, one is a UIFigure. Each figure has identical axes and identical annotiation boxes. The annotation object is not seen in the UIFigure. A confirmation box will appear in the UIFigure and when you press a button, it will delete the UIAxes and the annotation object will be revealed.

fig = figure('Units','pixels'); 
fig.Position = [150,150,560,420];
ax = axes(fig, 'Units','Pixels', 'Position', [25 25 510 380]); 
an = annotation(fig, 'TextBox',[.2 .2 .6 .6],'String','Anotation Text Box');

uifig = uifigure('Position',[sum(fig.Position([1,3]))+10,fig.Position(2:end)]);
uiax = uiaxes(uifig,'Position',ax.Position);  
uian = annotation(uifig, 'TextBox',[.2 .2 .6 .6],'String','Anotation Text Box');

waitfor(uiconfirm(uifig,'Press any button to remove UIAxes and reveal the annotation object.', 'Annotation demo')); 
delete(uiax)

Are there any solutions (or hacks) to this?

[Walter Roberson]

Andrew please clarify what it is you are trying to solve.
