Defining the Parent location of a UIAxes plot

Hi all,

This is a continuation of a project I'm working on that started over in [this] thread. I've created a script that generates a "moving message display" utilizing the text displays in a plot window, but now I'm taking it a step further by creating an app to house that code. I'm specifically running into a problem with trying to set the Parent location for the UIAxes plot. The app designer is throwing an error thinking that I'm trying to use the RightPanel as an index, but that's where I want the UIAxes plot to reside instead of generating in a new figure window, so I thought I needed to define the Parent location... Is there something glaringly wrong with my code?

Thanks for the help!

function RunButtonPushed(app, event)
             % Gather User Inputs from Left Panel of the GUI
             % Set Background and Text Colors according to the button selected by the User
             bgColor = app.BackgroundColorButtonGroup.SelectedObject.Tag; 
             txtColor = app.TextColorButtonGroup.SelectedObject.Tag;
             
             msg = app.MessageEditField.Value;  % Set the desired Message
             if isempty(msg)                    % If the User does not specify a message
                 msg = ' YOUR TEXT HERE ';      % Default to display of 'YOUR TEXT HERE'
             end
             
             t = now;                           % Grab current system time
             % Convert it to a datetime format and put that value in a string
             d = string(datetime(t,'ConvertFrom','datenum'));
             % Time = pad(d,2,'both');          % Pad each end of the string by two spaces

             spacer = "   ";                    % Create Spacer string for extra padding
             temp = floor(1 + (46-1).*rand(1,1)); % Create random temperature value

             % Concatenate all pieces in a string then convert it to a character array
             display = char(strcat(spacer,msg,spacer,"Today's Date Is: ",d,spacer,"The Current Temperature Is: ",num2str(temp),char(176),"C"));
             
             % Display the message back to the User on the UIAxes in the Right Panel
             ax = app.UIAxes('Parent',app.RightPanel);
             ax.Color = bgColor;
             ax.Box = 'on';
             hold on
             for i = 1:(length(display)+1)      % Loop once for length of entire message
                 cla(ax)                        % Clear previous Axes
                 ax = gca;                      % Create axis handle
                 ax.Color = bgColor;            % Set background color of the plot window
                 text('Parent',ax,display,'Color',txtColor,'FontSize',72,'FontName','LED Counter 7');  % Display message as text
                 
                 display = circshift(display,-1); % Circle Shift character array, Scrolling Left

                 i = i + 1;                     % Increment i
                 pause(0.5);                    % Pause for 0.5 sec
             end 
        end

Update: I shifted a few things around and I think I fixed everything, though is there a way to prevent the text display from being visible outside of the UIAxes window? It's sticking out on the right side

 % Display the message back to the User on the UIAxes in the Right Panel
 ax = app.UIAxes;
 ax.Parent = app.RightPanel;
 ax.Color = bgColor;
 ax.Box = 'on';
 hold on
 for i = 1:(length(display)+1)      % Loop once for length of entire message
     cla(ax)                        % Clear previous Axes
     text(ax,0,0.5,display,'Parent',app.UIAxes,'Color',txtColor,'FontSize',72,'FontName','LED Counter 7');  % Display message as text
     display = circshift(display,-1); % Circle Shift character array, Scrolling Left
     i = i + 1;                     % Increment i
     pause(0.5);                    % Pause for 0.5 sec
 end

remove

ax = gca;  %This creates a new axis when there isn't an axis in a figure window.

Edit:

This line isn't needed in for loop:

ax.Color = bgColor;

This line doesn't need to be in for loop:

text(ax,0,0.5,display,'Color',txtColor,'FontSize',72,'FontName','LED Counter 7');  % Display message as text

Also,

 ax = app.UIAxes;
 ax.Parent = app.RightPanel;
 ax.Color = bgColor;
 ax.Box = 'on';

can be written as

 app.UIAxes.Parent = app.RightPanel;
 app.UIAxes.Color = bgColor;
 app.UIAxes.Box = 'on';

Hi, thank you for your recomendation for cleaning up the code a bit, I'll implement those in my code. Do you know how to hide the text outside the Axes box? I think that's the only problem I'm encountering at this point.

[Kevin Holly]

Change the ClippingStyle of the uiaxes to rectangle.

app.UIAxes.ClippingStyle = 'rectangle'

[Lucas Lombard]

Hmm so I already had those options selected in the design mode side, adding it to the code didn't seem to change anything.

[Kevin Holly]

It worked for me.

Make sure clipping is on for your text:

text(ax,0,0.5,display,'Color',txtColor,'FontSize',72,'FontName','LED Counter 7','Clipping','on');

[Lucas Lombard]

That fixed it, thank you!
