Plot selection in appdesigner

Is it possible to have the "Edit plot" tool in an UIaxis in appdesigner? I need it to enable callback functions for selection of curves and surface objects.

Hi Jon,

To incorporate the plot’s callback function in an app designed with the UIAxes component, MATLAB's built-in callback functions can be used.

The ‘ButtonDownFcn’ callback is effective for detecting user interactions with the plot, such as selecting plotted objects.

Refer to the following example code snippet:

plot(app.UIAxes, x, y, 'ButtonDownFcn', @(src, event) plotClicked(app, src)); 

function plotClicked(app, src) 
    % Plot object 
    plotObject = src; 
    
    % Perform additional actions based on selection 
    disp(['Selected plot: ', plotObject]); 
    
    % Perform tasks on plot object 
end 

Refer to the following MathWorks Documentation to learn more about ‘ButtonDownFcn’ (Button Down Callback Function): https://www.mathworks.com/help/releases/R2022a/matlab/creating_plots/button-down-callback-function.html

I hope this helps.
