*
* initialize the underlying plot package (PPLUS) for a fresh plot
* (this routine is not called for an overlayed plot)

* programmer - steve hankin
* NOAA/PMEL, Seattle, WA - Tropical Modeling and Analysis Program
* written for VAX computer under VMS operating system
*
* revision 0.0 - 6/30/87 - extracted from DISP_SET_UP
* revision 0.1 - 7/21/87 - added XAXIS, YAXIS and WINDOW initialization
* revision 0.2 - 7/28/87 - removed LEV () to DISP_PREP, added documentation
* revision 0.3 - 8/26/87 - added TXTYPE YR
* revision 0.4 - 6/28/88 - added  AXLEN and AXSET
* revision 0.5 - 8/26/88 - removed SIZE
* revision 1.0 -  9/8/88 - removed all major re-setting to DISP_RESET 
* revision 1.1 - 1/26/89 - bug fix: 24-->13 for length of "date time" string 
* V200:   1/4/89 - major changes for plots with keys and joint contexts
* V230:   6/8/92 - added WIRE command (requiring WINDOW OFF) so set WINDOW dflt
*        7/22/92 - initialize ul_dolab so that /OVERLAYs following /NOLABEL
*                  will have predictable results
*        11/9/92 - unprotect colors if this is a fresh plot in a full window
*        1/28/93 - added args to plotify_grp_cx to promote thin regions to 2D
*       12/10/93 - set only the small tic size - do not mess with large tics
* V301:	 1/24/94 - turn on metafiles here instead of in XEQ_SET & START_PPLUS 
*	           (resolve problem of metafiles created with wrong name)
* V310:  3/21/94 - squeeze unneeded blanks from "FERRET Ver.3.10"
* v500:  1/26/99 - *kob* commented out PPLCMD call for aline, because this call
*                  was moved to disp_prep.F so reinitialization could occur for 
*                  plot overlays.
* v533:  6/27/01 - *acm* call PPLCMD to initialize AXTYPE,1,1 (not log axis) and
*		   initialize h_logaxis, v_logaxis to FALSE
* v533:  7/11/01 - *acm* call AXSET,1,1,1,1  to set to the default state of all axes on.
*      *acm* 10/01  remove VMS includes
* v540 *acm*  2/02 Do not call AXSET,1,1,1,1 - want PPL AXSET settings to persist
* V550 *acm* 12/02 use mode_labels and mode_logo to control labels and/or logo
* v552 *acm*  3/03 new param IAXSET to restore axes after PLOT/AXES/set plot.
* v552 *acm*  4/03 Delete symbols XAXIS_MIN, XAXIS_MAX, etc.  If they've
*                  been set by a previous plot, they dont get reset on plots
*                  like plot/vs xpts,ypts
* v580 *acm* 11/04 Fix bug 1009. Distinguish between axes which really have one 
*                  point, and those for which the hi and lo subscripts on the axes 
*                  are undefined. When undefined return zero from CX_DIM_LEN_ZERO in
*                  GET_CX_DIMS_ZERO. These axes are listed last in the heirarchy in 
*                  array plot_axis().  This means we can plot a variable with just 
*                  one point in their range (if /HLIMITS or /VLIMITS are used to give 
*                  PPLUS a range to draw).
* V600 *acm* 8/05 - Allow more digits in xrevision number
* V600 *acm* 5/06 - flag no_plot_yet for applying mode_linecolors setting ...
* V6.11 4/08 *acm* Fixes for bug 1571; call to PPL_AXES_RESTORE moved to DISP_INIT
*       *acm* 3/12 Add E and F dimensions (use nferdims in tmap_dims.parm)
* PyFr *kms*  7/13 Scale default lengths by pplscale; 
*                  do not reset minor tic size (not scaled!)
* V686 *acm* 11/13 Allow symbol names to be up to 120 characters long
* V686 *acm* 12/13 set up the label symbols LABNUM_E and LABNUM_F
* V695+ *sh*  3/15 remove movable label rotations (left behind by FMRC annotations)
