list box component how to code callback function for each selected option to display a seprate pi chart in matlab

You can create a list box component in a MATLAB GUI using the listbox function. To define a callback function for when an option is selected in the list box, you can use the Callback property of the list box.

Here is an example code snippet that demonstrates how to create a list box component and define a callback function to display a separate pie chart for each selected option:

main.m
% Create a figure
fig = figure;

% Define the list of options
options = {'Option 1', 'Option 2', 'Option 3'};

% Create a list box component
listbox = uicontrol('Style', 'listbox', 'String', options, 'Position', [50, 50, 100, 100], 'Callback', @displayPieChart);

% Define the callback function
function displayPieChart(src, event)
    % Get the selected option from the list box
    idx = get(src, 'Value');
    selectedOption = options{idx};
    
    % Create a separate pie chart based on the selected option
    figure;
    data = rand(1, 3);
    pie(data, {selectedOption, selectedOption, selectedOption});
    title(['Pie Chart for ', selectedOption]);
end

In this code snippet:

1. We create a list box component with three options.
2. We define a callback function displayPieChart that is triggered when an option is selected in the list box.
3. Inside the callback function, we retrieve the selected option and create a separate pie chart based on the selected option.

You can customize the options variable to include your specific data set or categories.
