Juergen:
I hope this is useful for you:

datos=Table[Sin[ i * j], {i,0,3,.1},{j,0,3,.1}];
<<Graphics`Legend`;
ShowLegend[
  ListDensityPlot[datos,
    DisplayFunction->Identity],{GrayLevel[1-#]&,10," 1","-1",
    LegendPosition->{1.1,-.4}}]

Asunto: [mg58653] ListDensityPlot Legend?

dear mathgroup,

how does one add a legend to a ListDensityPlot.
i've a matrix that contains only 0,1 or 2 entries. ListDensityPlot plots  
the regions in three different colors. i would like to add a legend that  
indicates the colors and their corresponding numbers (0,1, or 2).
Tom Wickham-Jones' ExtendGraphics package is doing almost what i want for  
ListContourPlot, however, for ListDensityPlot it's not working.
Any ideas?

thanks
juergen
