not possible as is. color intensity was part of the original MCL  
plotter -- you could map amplitude (or whatever) to how bright the  
layer color was. but i didnt implement this when i moved code to gtk,  
i cant rememeber why.
adding would be work but certainly doable. the easiest way would be  
to break up the functions 'draw-line-and-point' and 'draw-box-and- 
bubble' into methods (which i should have done anyway...) and move  
the clauses of the current case statement into the methods. then  
create a a NEW method that implements your colored points and make it  
a new style of plot.

yes this is easy, simply call 'plotter-redraw' after your changes.
