How to save GUI axes ?

I want to save the axes on the GUI, but he will save the entire window.

I want the axes part, what should I do?

code

function pushbutton1_Callback(hObject, eventdata, handles)
[FileName, PathName, ~] = uiputfile( ...
       {'*.png'},...
        'Save as');


ax1 = handles.axes1;

x  = rand(10,1);
y = rand(10,1);
scatter(x,y,'^')

new=FileName(1:end-4);
saveas(ax1, new,'png')

The saved .png like the following, but I want the axes part, and I don’t want the pushbutton, panel, table... etc. on the GUI.

Hi @han han,

I understand that you want to save just the axes of your plot as a PNG file, excluding any other elements like pushbuttons, panels, or tables. To achieve this, you can use MATLAB's ‘exportgraphics’ function.

Below is an example code demonstrating how to use ‘exportgraphics’:

function exportGraphicsExample
    hFig = figure('Position', [100, 100, 400, 300], 'Name', 'Export Graphics Example', 'NumberTitle', 'off');
    
    ax1 = axes('Parent', hFig, 'Position', [0.1, 0.3, 0.8, 0.6]);
    
    x = rand(10, 1);
    y = rand(10, 1);
    scatter(ax1, x, y, '^');
    title(ax1, 'Random Scatter Plot');
    
    uicontrol('Style', 'pushbutton', 'String', 'Save Plot', ...
              'Position', [150, 20, 100, 40], ...
              'Callback', @(src, event) savePlot(ax1));
    
    % Function to save the plot
    function savePlot(ax)
        [FileName, PathName] = uiputfile({'*.png'}, 'Save as');
        
        % Check if the user selected a file
        if isequal(FileName, 0) || isequal(PathName, 0)
            disp('User canceled the file selection.');
            return;
        end
        
        % Construct the full file name with path
        fullFileName = fullfile(PathName, FileName);
        
        % Use exportgraphics to save only the axes content
        exportgraphics(ax, fullFileName, 'Resolution', 300);
        
        disp(['Plot saved to ', fullFileName]);
    end
end

hope this helps.
