Dear Jim,

This almost exactly what I need. However, because I am not trying to  
plot price change as the color parameter, I need the scale to be  
positive only (0 to 1) and would like to be able to control the color  
scheme of the scale. I looked at the help file for map.market() and  
it's code but it seems to be inflexible in terms of changing the scale  
and the colors. I was wondering if map.market is an application of a  
more general plotting function? From my reading of the code it looks  
like that's not the case.

Anyhow I am very grateful.

Osman
