This is a screen dump of Freud. The window at the upper left is the main Freud window, and shows the current plot. There are two instantiated overlays -- a map overlay and a contour overlay.

The appearance of the map is controlled by the window at the upper right. The contour line style and area fill styles are controlled by the contour window at the lower left. Finally, the dialog in the lower right corner of the window is used to control the position of plots on a page.

More detailed info is available in the online Freud manual.
