17. Displaying XAS files graphically

XAS provides facilities for simple standard plotting and visualization of data. These facilities are not intended for publication quality plots, for which one may export XAS files to one's favourite package.
See in particular elsewhere for usage of SAOimage for image display and of IDL for general plotting.

Plotting is done by the user by just a couple of "client" commands which use an underlying graphic server. There are two main kind of servers, X-window and PostScript.

One proceeds as follows :

create a server instance
set the appropriate environment variables
invoke the display command to plot a file in a fresh frame
invoke the overtrace command to plot a file over the current plot
one may additionally control the plotting behaviour of the server.
at the end one terminates the server.
