Hi Jim and thanks for help

I will need some help to make
-the legend visible (probably at the right side of the window)
-split the legend at 0.1 steps -1,-0.9,-0.8.....1 and 

-assign a color heat.color(30). I have selected orange and reds
-show me the way to change the size of legend if it would be needed




par(mar=c(7,4,4,6))
test<-matrix(data=runif(10000),nrow=100)
color2D.matplot(test,axes="F",xlab="",ylab="",show.legend=FALSE) #,show.legend=TRUE
axis(1,at=seq(1:nrow(test)),labels=seq(201,300)) #
color.legend(11,6,11.8,9,seq(-1,1,length=10),rect.col=heat.colors(30),gradient="y")

I would like to thank you in advance for your help

Regards
Alex

Hi Alex,
If all else fails, look at color.legend (plotrix).
