Consider marking tests that depend on a gui. about oct2py HOT 6 CLOSED

Is the intent to avoid error when gnuplot is not available, or to avoid having the gui pop up? If it is the latter, I could make the tests spawn figures without displaying them (as is done by Octavemagic).

I'm not sure what the problem is exactly but sometimes the test_plot just hangs in the gentoo building/testing environment.

This happens on Travis occasionally as well. I am going to add the option to save figures to a file rather than displaying them, and do that in the test instead.

Yes, that is probably an even better idea.

eval and the dynamic functions now accept the following keywords:

        plot_dir: str, optional
            If specificed, save the session's plot figures to the plot
            directory instead of displaying the plot window.
        plot_name : str, optional
            Saved plots will start with `plot_name` and
            end with "_%%.xxx' where %% is the plot number and
            xxx is the `plot_format`.
        plot_format: str, optional
            The format in which to save the plot (PNG by default).
        plot_width: int, optional
            The plot with in pixels (default 400).
        plot_height: int, optional
            The plot height in pixels (default 240)
