I have a Matlab code with multiple figures present in it.But I want to save Figure 2 as a jpg format.

I have seen people using "saveas(gcf,'Barchart.png')" and gcf is used for getting the current Fig. But I want only Figure2 to be saved as Barchart.png and not any other figure.

在 MATLAB Online 中打开

saveas(2,'filename.jpg')

For more security,

fig2 = figure(2);
saveas(fig2, 'filename.jpg')

.. you should probably have a handle to the figure anyway, as you need to use the handle in some operations to ensure that you are working with the figure you want.
