PROCEDURE: zlim,lim, [min,max, [log]] PURPOSE: To set plotting limits for plotting routines. This procedure will add the tags 'zrange', 'zstyle' and 'xlog' to the structure lim. This structure can be used in other plotting routines. INPUTS: lim: structure to be added to. (Created if non-existent) min: min value of range max: max value of range log: (optional) 0: linear, 1: log If lim is a string then the limit structure associated with that "TPLOT" variable is modified. See also: "OPTIONS", "YLIM", "XLIM", "SPEC" Typical usage: zlim,'ehspec',1e-2,1e6,1 ; Change color limits of the "TPLOT" variable ; 'ehspec'.
