As the documentation clearly states, saveas saves the figure: this includes all of the figure, which might include a title, axes, axes labels, a legend, etc., and not just what is inside the axes.

You have two main options:

1. Expand the image to fill the entire figure (set the axes/figure positions), then use saveas.
2. Use imwrite to save the data array (the better choice).
