Hello,
I simply want to export a figure of a specific size (6 x 9 inches) with the function exportgraphics as described here (https://www.mathworks.com/help/matlab/creating_plots/save-figure-at-specific-size-and-resolution.html)
The following code doesnt return any errors but the figure is empty. Any tips ?
Thank you,
t = tiledlayout(1,1,'Padding','tight');
t.Units = 'inches';
t.OuterPosition = [0.25 0.25 6 9];
nexttile;
figure
subplot(2,1,1);
x = linspace(0,10);
y1 = sin(x);
plot(x,y1)
subplot(2,1,2);
y2 = sin(5*x);
plot(x,y2)
exportgraphics(t, 'test.jpg', 'Resolution', 300)

Hi,
You need to specify the parent figure to use the exportgraphics.
I am unable to figure out completely what's happening in the code.
This might do it.
fig = gcf;
exportgraphics(fig, 'test.jpg', 'Resolution', 300)

you created a tiledlayout in one figure, set some of its characteristics but didn't add anything to it. Then you created a new figure with subplots, then you exported the (empty) tiledlayout.
Instead, use tiledlayout to set your layout shape, drop the call to figure, and use nexttile in place of the calls to subplot:
t = tiledlayout(2, 1, 'Padding', 'tight');
t.Units = 'inches';
t.OuterPosition = [0.25 0.25 3 3];
nexttile;
x = linspace(0,10);
y1 = sin(x);
plot(x,y1)
nexttile;
y2 = sin(5*x);
plot(x,y2)
exportgraphics(t, 'test.jpg', 'Resolution', 300)
