[ncl-talk] Discrete Color Bar

[Dennis Shea]

The Classification examples illustrate how to use some of the
resources... For example

  res at cnLevelSelectionMode = "ExplicitLevels" ; set explict contour levels
  res at cnLevels         = integertobyte( ispan(2,18,1) )

  res at lbLabelPosition  = "Center"           ; label position
  res at lbLabelAlignment = "BoxCenters"       ; label orientation
  res at lbLabelStrings   = ispan(1,18,1)
