I have been struggling to get the legends in ggplot2 right or do away with them altogether (on which I have already sent a post). In the following code, the labels argument in the scale_colour_gradient2 does not give me the desired labels in the legend. Could someone explain? qplot(Year,CDR,data=b3,colour=Phase,geom=c("point","line"),legend.position="bottom")->p p+scale_colour_gradient2(limits=c(1,2), midpoint=1,low="magenta", mid="magenta", hi...

Hi! I'm not experienced very experienced with R and i'm looking for a way doing plots like in this example http://www.mathworks.de/matlabcentral/fx_files/23566/2/color_line3.png, which basically it is a 2d plot in which the 3rd dimension (variable) is color coded. I have only seen elsewhere that it is possible to color code dots in a scatter plot and I tried it with success although I
