How to save a figure of a specific size with exportgraphics

56 views (last 30 days)
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)

How about:
t = tiledlayout(2, 1, 'Padding', 'tight');
t.Units = 'inches';
t.OuterPosition = [0.25 0.25 6 6];
nexttile;
x = linspace(0,10);
y1 = sin(x);
plot(x,y1)
nexttile;
y2 = sin(5*x);
plot(x,y2)
% if you want your figure to go back to where it was after export, you can
% store the current units and position and set them back after exporting
set(gcf,'Units','inches','Position',[1 1 8 8]) % I used width and height of 8 to be sure nothing got cut off
exportgraphics(t, 'test.jpg', 'Resolution', 300)
