> Hi Jim, i think you could not get my point. I did not want to put red-blue color there. I want to put a pallet which will describe the values of r. please have a look on following : http://bp0.blogger.com/_k3l6qPzizGs/RvDVglPknRI/AAAAAAAAAKo/itlWOvuuOtI/s1600-h/pairwise_kl_window60.png. Please see how a color pallate is added on the right side of this plot describing the value of red color, value of blue color etc.
