Does app designer support gscatter ?

Hi all,

I want to draw a gscatter plot in the app designer.

Does app designer support gscatter?

If so, can you show an example code?

Thank you.

Sincerely yours.

Hi,

Yes, the MATLAB App Designer supports “gscatter” function for creating grouped scatter plots. It can be done directly within a UIAxes component. Here's an example:

• Set Up the App: Add a UIAxes and a button to the app in the App Designer.
• Button Callback: Use the following code in the button's callback to generate the plot:

% Sample data
x = randn(100, 1);
y = randn(100, 1);
group = randi([1, 3], 100, 1);
% Clear and plot in UIAxes
cla(app.UIAxes);
gscatter(app.UIAxes, x, y, group, 'rgb', 'o', 8);
% Add labels and title
xlabel(app.UIAxes, 'X-axis Label');
ylabel(app.UIAxes, 'Y-axis Label');
title(app.UIAxes, 'Grouped Scatter Plot');

Run App: Clicking the button will display the scatter plot within the UIAxes.

Outputs:

1. Before clicking button 2. After clicking button

For reference, check the documentation for “gscatter” function.

Hope this helps!

I seem to recall that at the time the question was originally asked (2019), gscatter was not supported for uiaxes

Hi,

I just wanted to share that I was able to get the code running in my case, and I used the R2019b version of MATLAB for the implementation. Hope it helps!
