PROCEDURE: ylim [, str [ , min, max, [ LOG=log ] ] ] PURPOSE: Sets y-axis limits for plotting routines. Adds the tags 'yrange', 'ystyle' and 'ylog' to the structure str, or to the limit structure associated with the string str. INPUTS: str is a: CASE 1: structure (or zero or non-existent) Structure to be added to. (Created if non-existent) CASE 2: string (handle associated with a "TPLOT" variable) The limits structure associated with this string is used. This structure can be retrieved with the "GET_DATA" procedure. min: min value of yrange max: max value of yrange KEYWORDS: LOG: (optional) 0: linear, 1: log DEFAULT: Sets default tplot limits. STYLE: value to set the IDL plot YSTYLE keyword Typical usage: ylim,lim,-20,100 ; create (or add to) the structure lim ylim,'Ne',.01,100,1 ; Change limits of the "TPLOT" variable 'Ne'. NO INPUTS: ylim ; Set "TPLOT" limits using the cursor. SEE ALSO: "OPTIONS", "TLIMIT", "XLIM", "ZLIM" CREATED BY: Davin Larson VERSION: ylim.pro LAST MODIFICATION: 01/06/25
