How can I control the figure size or aspect ratio?
There are three basic parameters: screenratio, screenht, and sreenwd. If sreenwd is not provided, it is calculated as screenht/screenratio. The defaults are:
For a finer control, you can use xinch= (horizontal size), yinch= (vertical size), xll=, xur=, yll=, yur= (x and y coordinates for lower-left and upper-right corners). If not provided, they are calculated from screenht and screenwd.
These parameters apply to sfcontour, sfgraph, sfgrey, sfplotrays, and sfwiggle.
