How can I save only content of matlab figure ?

i am using the following code: fig=figure,imshow(RIm); saveas(fig,'22.jpg');

It saves as image but with white border. How can I save only content of the figure.

x = rand(20,1) ;
y = rand(20,1) ;
plot(x,y)
set(gca,'LooseInset',get(gca,'TightInset'));
saveas(gcf,'junk.jpg')
