PROCEDURE: xlim,lim, [min,max, [log]] PURPOSE: To set plotting limits for plotting routines. This procedure will add the tags 'xrange', 'xstyle' and 'xlog' to the structure lim. This structure can be used in other plotting routines such as "SPEC3D". INPUTS: lim: structure to be added to. (Created if non-existent) min: min value of range max: max value of range KEYWORDS: LOG: (optional) 0: linear, 1: log See also: "OPTIONS", "YLIM", "ZLIM" Typical usage: xlim,lim,-20,100 ; create a variable called lim that can be passed to ; a plotting routine such as "SPEC3D".
