NAME: TIMEAXIS_text PURPOSE: Plot a time axis. CATEGORY: CALLING SEQUENCE: timeaxis_text, [t] INPUTS: t = optional array of seconds after midnight. in KEYWORD PARAMETERS: Keywords: JD=jd Set Julian Day number of reference date. FORM=f Set axis label format string, over-rides default. do help,dt_tm_mak(/help) to get formats. For multi-line labels use @ as line delimiter. NTICKS=n Set approximate number of desired ticks (def=6). TITLE=txt Time axis title (def=none). TRANGE=[tmin,tmax] Set specified time range. YVALUE=Y Y coordinate of time axis (def=bottom). TICKLEN=t Set tick length as % of yrange (def=5). /NOLABELS means suppress tick labels. /NOYEAR drops year from automatically formatted labels. Doesn't apply to user specified formats. LABELOFFSET=off Set label Y offset as % yrange (def=0). Allows label vertical position adjustment. DY=d Set line spacing factor for multiline labels (def=1). COLOR=c Axis color. CHARSIZE=s Axis text size. CHARTHICK=cth thickness of label text (def=1). THICK=thk thickness of axes and ticks (def=1). MAJOR=g Linestyle for an optional major tick grid. MINOR=g2 Linestyle for an optional minor tick grid. NOTIME = if set, do not display time label PLABELOFFSET = offset label by this number of pixels Will supersede 'labeloffset' keyword. ONLYLABEL = if set, will display label only, no axis, no tick marks. AddInfo=addInfor Array of additional data to be displayed under ticks AddFormat=addFormat Array of format strings for additional data AddLabel=addLabel Array of strings to put in front of first tick info Add_ds=Add_ds Array of strings to put after the last tick on each line for BIGPLOT=bigplot added to allow some special settings for the large CDAWeb inventory plots. OUTPUTS: COMMON BLOCKS: NOTES: Notes: To use do the following: plot, t, y, xstyle=4 timeaxis_text If no arguments are given to TIMEAXIS_text then an axis will be drawn based on the last plot, if any. Try DY=1.5 for PS fonts. MODIFICATION HISTORY: R. Sterner, 25 Feb, 1991 R. Sterner, 26 Jun, 1991 --- made nticks=0 give default ticks. R. Sterner, 18 Nov, 1991 --- allowed Log Y axes. R. Sterner, 11 Dec, 1992 --- added /NOLABELS. R. Sterner, 20 May, 1993 --- Made date labeling (jd2mdays). Allowed CHARSIZE for SIZE. Robert.M.Candey.1@gsfc.nasa.gov, 22 Sept 1993; added addInfo and addFormat to put data under the times under the tick marks R.
