   What I am doing is reading in an 8-bit image and would like to
   pick some points on it.  I can plot the points on the image
   but every point that is plotted Matlab clears the figure and 
   redraws the whole thing.  This is WAY too slow.

   What I am hoping is that there is some way in Matlab to turn
   off the redraw/refresh??

In Matlab 4, you can do this by specifiying a plot as a graphics
object then using the 'set' command to change the data in the plot
without redrawing the axis.  Look at ODE23P for further clues.

   Thanks.

You're welcome.

   Craig.
