Showing robot in app designer UIAxes

I want to draw a robot using the show() function from Robotics System Toolbox in App designer UIAxes.

https://www.mathworks.com/help/robotics/ref/rigidbodytree.show.html

I'm trying to display it using this description: https://www.mathworks.com/help/matlab/creating_guis/graphics-support-in-app-designer.html

However, the function does not work if I put app.UIAxes in the first argument nor if I specify Axes as a Name-Value argument:

show(app.UIAxes, robot);
show(robot, 'Parent',app.UIAxes);

I'm getting:

Undefined function 'show' for input arguments of type 'matlab.ui.control.UIAxes'.

or:

The value of 'Parent' is invalid. Functionality not supported with UIAxes.

Is there any other way to get the show() function into app designer?

Do you have the Robotics System Toolbox installed? Type ver in the command window to see. If not, and you have access to it, you can install it using the Add-Ons Explorer.

Once that toolbox is added, the correct syntax is option 2: 'Parent'.

Yes, I do have Robotics System Toolbox installed. And it works when I use only

show(robot);

However, that opens up a new figure. I want to use the UIAxes in my app. When I run

show(robot, 'Parent',app.UIAxes);

The full error is this:

Error using robotics.manip.internal.RigidBodyTree/parseShowInputs (line 1084)

The value of 'Parent' is invalid. Functionality not supported with UIAxes.

Error in robotics.manip.internal.RigidBodyTree/show (line 1033)

parser = obj.parseShowInputs(varargin{:});

Error in rigidBodyTree/show (line 839)

ax = obj.TreeInternal.show(varargin{:});

"Functionality not supported with UIAxes."

That seems pretty clear. I don't think there is a way to use it in app designer apps, other than opening up a separate figure window with a regular axes to show it.

[Hannes Daepp]

Cam is correct. Currently rigidBodyTree.show() only works with axes, and not uiaxes, but we are aware of this limitation and working to add support in a future release.

[Robert Pastor]

Thanks, I thought I was doing something wrong. I will use a separate figure for now.

Is there any progress on solving this issue? In the latest Matlab version, 2023b, rigidBodyTree.show() is still unable to plot the results on app.UIaxes ...
