#!N #!EC #!N #!N Using the AutoColor tool to color 2-dimensional 
data is the simplest visualization method available. By default, AutoColor assigns 
blue to the smallest values and red to the largest. (If 
the data are vector, the colors are based on the magnitude 
of the vectors). #!N #!I0 #!N  #!F-adobe-times-medium-r-normal--18*   #!N #!N #!I30 #!N
