Floating point grid does not display or label properly

Description

A floating point grid does not display or label properly in ArcView Spatial Analyst.

Cause

The range of values of the grid is much smaller than the range of values set in the legend.

Solution or Workaround

1. Open a new script window.
   
   
   A. Activate the Project window.
   B. Click the Scripts icon.
   C. Click New.
   
   
2. Paste the following :
   
   

   Code:
   '-- Get the original grid legend and write parameters to a temporary table
   theview = av.getactivedoc
   thetheme = theview.getactivethemes.get(0)
   theleg = thetheme.getlegend
   thenum = theleg.getnumclasses - 1
   thevtab = vtab.makenew("c:\temp\class2.dbf".asfilename, dbase)
   thevtab.seteditable(true)
   therecfld = field.make("Recno", #FIELD_DECIMAL, 6,0)
   thelfld = field.make("Label", #FIELD_CHAR, 30, 0)
   therfld = field.make("Range", #FIELD_CHAR, 30, 0)
   theminfld = field.make("Min", #FIELD_DECIMAL, 15, 5)
   themaxfld = field.make("Max", #FIELD_DECIMAL, 15, 5)
   thevtab.addfields({therecfld, thelfld, therfld, theminfld, themaxfld})
   for each i in 0..thenum
     therec = thevtab.addrecord
     theleglist = theleg.returnclassinfo(i)
     thelabel = theleglist.get(0).clone
     therange = theleglist.get(1).clone
     themin = theleglist.get(3).clone
     themax = theleglist.get(4).clone
     thevtab.setvalue(therecfld, therec, (i + 1))
     thevtab.setvalue(thelfld, therec, thelabel)
     thevtab.setvalue(therfld, therec, therange)
     thevtab.setvalue(theminfld, therec, themin)
     thevtab.setvalue(themaxfld, therec, themax)
     theleglist.empty
   end
   thevtab.seteditable(false)
   
   theleg.save("c:\temp\one.avl".asfilename)
   
   '-- Reclass grid using the temporary table
   g = thetheme.getgrid.reclass(thevtab, theminfld, themaxfld, therecfld, true)
   
   '-- Join attributes in temp table to reclass grid
   thegvtab = g.getvtab
   thevalfld = thegvtab.findfield("value")
   thegvtab.join(thevalfld, thevtab, therecfld)
   g2 = g
   
   '-- Make new legend and assign values, symbols and labels
   thenewleg = legend.make(#SYMBOL_FILL)
   thenewleg.load("c:\temp\one.avl".asfilename, #LEGEND_LOADTYPE_ALL)
   thegtheme = gtheme.make(g2)
   for each j in 0..thenum
     'thel = theg2vtab.returnvalue(thelabelfld, j)
     the2leglist = thenewleg.returnclassinfo(j)
     jj = j + 1
     the2leglist.set(1, jj.asstring)
     the2leglist.set(3, jj)
     the2leglist.set(4, jj)
     thenewleg.setclassinfo(j, the2leglist)
   end
   
   '-- Set legend and add grid to view
   thegtheme.setlegend(thenewleg) 
   theview.addtheme(thegtheme)
   

   
   
3. Select Compile from the Script menu or click the
   
   button.
4. Open the view and make the problem grid theme active.
5. Click directly on the script window and click the
   
   button to run the script.
