Hi Donna...

I'd like to just be able to draw some text at particular values in
the data set (i.e. x = datamin, y=-1, and x=datamax, y=-1 for my horizontal
colorbar). Is this a big deal, or is there a simple way to do it?

def drawString(self, string, position, color=None, center=0,
  font="futural",start=[0.,0.,0.], base=[.1,0.,0.],
  up=[0.,.1,0.],size=None ):

  """
  Draw a string of characters on this display.  <string> is the
  string of characters.  <position> is the starting location for the
  string drawing, expressed as a list/tuple of 2 or 3 values (x,y,z).
  <color> is the color (e.g., "red" or java.awt.Color; default
  white).  <center> if true will center the string.  <font> defiles
  the HersheyFont name to use.  <start> defines the relative location
  of the starting point (x,y,z; default = 0,0,0).  <base> defines the
  direction that the base of the string should point (x,y,z; default
  along x-axis).  <up> defines the direction of the vertical stroke
  for each character (default = along y-axis).  <size> is the relative
  size.  Returns the index to the shape of the text (useful for
  moving).

so, for example:

  disp.drawString("My string",(2.3, -2.1),color='green', center=1)

Hope that helps.
