Re: trajectory plot + colorbar

[Jaison Kurian <jaison@xxxxxxxxxxxxxxxxxx>]

Hi Michael,
              You can use "PPL SHAKEY" to turn your color key. Refer
user manual Appendix C, Sec2.12 SHAKEY to find the usage. The trick is
to interchange yposition_low & yposition_high ( to turn vertical, default
color key) in SHAKEY. For example...

        yes? use coads_climatology
        yes? set reg/l=1/x=30:120/y=-30:30
        yes? fill sst         ! to make a plot and get the values for
        yes? ppl list shakey  !   arguments of default shakey

                 DO KEY  ORIENT  LAB SIZE  LAB INC  LAB DIG  LAB LEN
                      1       1      0.00        0        3        9


                 DEFAULT KEY POSITIONING
                 X LO     X HI     Y LO     Y HI
                 9.45     9.71     1.40     7.40
        yes? fill/set sst    ! to make a plot with "reversed"  color key
        yes? ppl shakey ,,,,,,,,7.40,1.40  ! changing only y_values
        yes? ppl fill

  You can easily modify "polymark.jnl" to make an additional option for 
shakey as 7th argument. Make the following change in polymark.jnl;
	
	1. add /set_up qualifier to polygon command line (line No.68) like

$1/coord_ax=($PLMpoly_ax)/set_up  PLMxpoly+PLMxpolymark, PLMypoly+PLMypolymark, PLMpolydata  

        2. Add the following lines after the above one

ppl shakey $7" "
ppl fillpol/over

        3. In the begining "usage" part of the jnl file add some comments 
		for your later reference..like

! Usage:                  $1        $2    $3     $4      $5      $6      $7
! Yes?  GO polymark polygon_command xpts ypts [values] [shape] [scale] [shakey]
!
! $7 - ppl shakey arguments to control the color key orientn. and labelling
!                 in "double quotes" like "1,1,0,0,3,9,9.5,9.8,7.4,1.4"
!                    or ",,,,,,,,7.4,1.4"
!                 after making a dummy plot, use "PPL LIST SHAKEY" to
!                     see the default values

Notes that 7th argument to the new jnl file should be enclosed in double 
quotes.

Hope this helps....

With Regards

Jaison
