NAME: VER PURPOSE: Plot a vertical line on a graph at specified x value. CATEGORY: CALLING SEQUENCE: ver, x INPUTS: x = X value of vertical line. Scalar or array. in KEYWORD PARAMETERS: Keywords: /DEVICE means work in device coordinates. /NORMALIZED means work in normalized coordinates. Default is data coordinates. LINESTYLE=s. Linestyle (def=!p.linestyle). COLOR=c. Line Color (def=!p.color). THICKNESS=thk Line thickness (def=!p.thick). FILL=clr Optional color to fill between line pairs. Fills between lines 0 and 1, 2 and 3, and so on. POINTER=pt Draw arrowhead pointers at top and bottom instead of lines. Arrowhead dimensions may be given as fraction of screen or plot window size, the value of pt is height, or [height, width]. For /pointer the default used is [.03,.03]. /BOTTOM used with POINTER to plot bottom pointers only. /TOP used with POINTER to plot top pointers only. /OUT Keep pointers outside axes (Data coord only). OUTPUTS: COMMON BLOCKS: NOTES: Note: see hor. MODIFICATION HISTORY: R. Sterner, 2 Aug, 1989. R. Sterner, 21 May, 1992 --- fixed for log Y axes. R. Sterner, 3 Nov, 1992 --- Added /device. R. Sterner, 27 Jan, 1993 --- dropped reference to array. R. Sterner 20 Jun, 1993 --- added /norm. R. Sterner 1994 Feb 2 --- Add THICK. R. Sterner, 1994 Jun 3 --- Added FILL. R. Sterner, 1994 Jun 16 --- Added POINTER. R. Sterner, 1997 Jul 11 --- Added /OUT.
