Re: Color bar data appearance problem

[Jaison Kurian <jaison@xxxxxxxxxxxxxxxxxx>]

Hi Yogesh,
             Let me explain in detail. In previous mail i explicitly pointed that
you have to use /set qualifier with fill or shade command while using ppl shakey
(since it is not a stand alone command). From your mail..

   ppl shakey 1, 1, 0.10, 0, -1, 9, 0, 0.12, 0.12
   fill/nolab/lev=(370,382,0.5) sst+348;go land

 It should be like :

   fill/nolab/lev=(370,382,0.5)/set sst+348        ! note the /set qualifier
   ppl shakey 1, 1, 0.10, 0, -1, 9, 0, 0.12, 0.12  ! ky_hi(10th argument) is missing    
   ppl fill                                         
   go land

 While increasing the size of numeric labels, the decimal places maynot be displayed 
depending on the size of viewport and margins. In this case i would strongly recommend 
you to define a new viewport with slighly less x_size than the default one like 

     define view/xlim=0:0.97/ylim=0:1 view_main
     set view vmain
  
  Default viewport have xlim=0:1 & the 0.03 difference in the newly defined viewport
will make room for the color key with complete numeric labels. Please have a look at 
the example below. If you want change the location of the color key, then define the
main viewport according to that.

Example :

        define view/xlim=0:0.97/ylim=0:1 vmain       ! make room for color key labels
        set view vmain                               !    "
	set data coads_climatology
        set reg/x=100:300/y=-50:50/l=1

        fill/set/levels=(295,306.5,0.5) sst+273.15   !  note the /set qualifier 
        ppl shakey , , 0.15, , -1, , , , ,           !  "location of" shakey command
        ppl fill                                     ! get the plot
        go fland 20 black


Hope this helps

with regards 


Jaison
