How to save figures directly to a folder without having them display?

I have a set of plots, in other words figures, that need to be saved directly to the folder. I have the code set up where it saves the figures to a folder, but they display and then close. I don't even want them to display, rather save directly to the folder. Can Someone write up a small example or at least tell me the commands needed?

Hi Zach,

When you create a figure, you can set the 'visibile' property to 'off', which will cause it not to display. Then anything you plot on that figure will also not be displayed.

Here is a brief example:

f = figure('visible','off');
plot(1:10); % Do whatever plotting you want to here
saveas(f,'savedFigure','jpg');

The figure will still be saved in your Workspace as 'f' after this, but MATLAB will not have displayed it in a figure window.

What happens if I have a for loop controlling the number of plots? The code you gave me was for a single plot, what if I have t = 30 plots?

Did you try making f a cell array?

[Walter Roberson]

for t = 1 : 30
    f = figure('visible','off');
    plot(rand(1,10)); % Do whatever plotting you want to here
    filename = "savedFigure" + t + ".jpg";
    saveas(f, filename);
end

,,, except that in practice you would likely instead use

f = figure('visible','off');
for t = 1 : 30
    plot(rand(1,10)); % Do whatever plotting you want to here
    filename = "savedFigure" + t + ".jpg";
    saveas(f, filename);
end

or else

for t = 1 : 30
    f(t) = figure('visible','off');
    plot(rand(1,10)); % Do whatever plotting you want to here
    filename = "savedFigure" + t + ".jpg";
    saveas(f(t), filename);
end
