Re: trajectory plot + colorbar
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
