[gradsusr] Change Numbers for Words: CBARN

[Matt Alonso]

Hi Guisseppe,

It has been a bit since I've done much scripting in grads so this might not
be the optimal approach; it depends on how flexible this needs to me.  I've
never tried passing arrays as function args but you might want to try that.

There are 2 main things you need to do:

1) Create an array at the top of the function w/the text you want displayed:

labels.1=''
labels.2='cold'
labels.3='warm'
.....

2) Then change the code that plots the strings

*   Put numbers under each segment of the color key
*   num started at 0 but the array index for labels started
*   at 1, so we need to account for that
    labNum=num+1
    label=labels.labNum
    if (num < cnum-1)
      if (vert)
        xp=xr+stroff
        'draw string 'xp' 'yt' 'label
      else
        yp=yb-stroff
       'draw string 'xr' 'yp' 'label
      endif
    endif

I haven't actually tried this but it seems like it should work.

Let me know how it goes.
