How to remove the boxes in the contour labels????

[Charles Seman]

Mald,

I'm not sure if this might be of some help?  Please find attached a
GrADS script function clabel.gsf which is a script to plot contour
labels interactively. Also attached is a GrADS script fig1ab_sd.gs which
uses clabel.gsf...  If you find this useful, and have questions, please
let me know...
Thanks,
Chuck

some documentation:
...in fig1ab_sd.gs, input parameters for "clabel" (need 3 parameters:
csiz = contour label size, cformat = arithmetic format, and clist =
contour values to plot (here, 4 values in "sd_level"; sd_style defines
contour line style for each contour value in sd_level)):
*
*  Define the contour levels for the sample standard deviation...
*
sd_level = '0.2 0.5 0.8 1.1'
*sd_style = ' 5   3   2   1'
sd_style = ' 1   1   1   1'
*sd_label = 'off'
*sd_label = 'on'
sd_label = 'manual' ; csiz = 0.08 ; cformat = '%3.1f'

...further down in fig1ab_sd.gs, a loop to plot standard deviation
contour line and prompts user whether to label it using "clabel()" (here
contour lines and labels are plotted one-by-one), and after each
contour, prompts user for a replot to retry contour label; goes on to
next contour level if user does not type "yes":

  n=1 ; sd_clev = subwrd(sd_level,n) ; sd_cstyle = subwrd(sd_style,n)
  while ( sd_clev != '' )
    say 'n, sd_clev = 'n', 'sd_clev
    'set gxout contour'
    'set clevs 'sd_clev
    'set cstyle 'sd_cstyle

    if( sd_label = 'manual' )

      say 'Contour level = 'sd_clev
      say 'Do you want to plot a contour label?'
      say 'Type y(es) or Y(es), or press "ENTER" to continue...'
      pull plot
      if( plot='y' | plot='yes' | plot='Y' | plot='Yes' )
        clabel(csiz,cformat,sd_clev)
      endif
      say
      say 'Do you want to replot panel?'
      say 'Type y(es) or Y(es), or press "ENTER" to continue...'
      pull replot
      if( replot='y' | replot='yes' | replot='Y' | replot='Yes' )

          'set strsiz 0.08'
          'draw string 'xmm' 'ymm' Data: 'min_max' '
        endif
        if( plot_min_temp = 'yes' )
          say
          say '   plot level of minimum temperature...'
          say
          j=1
          while ( j <= ny )
            'set y 'j
