Hi all,

 I am using databox-0.7.0.0 to plot my graph. I was able to do it very nicely
 with out any problems, but

 1)Is there any possibality to change the color of the graph at certain
range           
  of values,
  ex: peaks, noises, spikes etc

Please help me out regarding this,

Thanking u all in advance.
