Hi Laura,
I understand you want to save your graph as a jpg image. I belive saveas function is not supported with figures created using uifigure, which is the type of figure used in MATLAB App Designer.
However, exportgraphics is designed to work with uifigure-based figures, making it the recommended approach for saving graphics from App Designer apps.
Please find the below code for refrence:
% Create some data and plot it
x = linspace(0, 2*pi, 100);
y = sin(x);
fig = figure;
plot(x, y);
% Save the figure to a JPG file using exportgraphics()
filename = 'plot_exportgraphics.jpg';
exportgraphics(gca, filename);
I hope it helps!
