Stata Tip 12: Tuning the Plot Region Aspect Ratio

Sometimes you want a graph to have a particular shape. Graph shape is customarily quantified by the aspect ratio (height/width). One standard way of controlling the aspect ratio is setting the graph height and width by specifying the ysize() and xsize() options of graph display. See also [G] graph display and [G] region options. These options control the size and, thus, the shape of the entire available graph area, including titles and other stuff beyond the plot region. At best, this is an indirect way of controlling the plot region shape, which is likely to be your main concern.
