Automatically remove white space from figure

How do I remove the white space from the figures ? I don't want to have to save the image then manually crop it.

Instead of Matlab's dumb figure it would be something like

smart_figure('NoWhiteSpace');
plot(..);

or

figure;
plot(..);
smart_clean('NoWhiteSpace');

Is there such a function ?

Try the new exportgraphics() function.

exportgraphics does not support to save all file types, for example, if I want to save a vector graphic (.svg) format, then what could be alternate solutions?

[Image Analyst]

I don't know. Call tech support and ask them.

It worked for me. Thanks!

@Ajay Kumar

exportgraphics(gca, 'output.eps', 'ContentType', 'vector');

This problem can be addressed manually in Export setup. Once figures are done File--> Export setup --> Size --> Check expand axes to fill figures.

[Tong Zhao]

Thank you, it worked, but I have an additional question: when the axes fills the figure, it breaks the aspect ratio of the content. How can I make sure that the aspect ratio stays the same when filling?

[Image Analyst]

What is in your axes? Line plots? Images? If it's images, use

axis('on', 'image');

to make sure the aspect ratio is correct.

Attach images showing what you have and what you want.

You can change the amount of gray padding about your axes by setting the Position property of the axes.

I find the following really useful:

First, assemble your figure as you normally would. Then, try this:

I0 = getframe;
imwrite(I0.cdata, fullfile(path,'image.png'))        

I have the impression that it needs some time for saving, so if used in code where stuff happens after this line it can sometimes give weird results. If you have the figure ready and then execute the code from the command line, it normally works beautifully.
