...EdgeColor" so I've been working on trying to overlay two plots of the same points, one plotted with fills and the other plotted with edge outlines (here is my conceptual code): pfill <- ggplot(data=DF, aes(x=X, y=Y)) + geom_point(aes(colour=TRT),size=4) + scale_colour_grey(end=0.8) + theme_bw pedge <- ggplot(data=DF, aes(x=X, y=Y)) + geom_point(aes(colour=TRT),size=4) + scale_colour_grey(end=0.8) + scale_shape(solid=FALSE) + theme_bw However, I can't figure out the correct syntax, if this is ev...

...diamonds in a grey scale instead of colors. I accomplished this (see graph 2) until I overwrote the label title for the treatments and the colors came back (graph 1). I used these two commands: p=ggplot(data = test, aes(x = YEAR, y = TOTAL, colour = TREATMENT)) + geom_point() + facet_wrap(~country)+scale_colour_grey()+ scale_y_continuous("number of votes")+ scale_x_continuous("Years")+ scale_x_continuous(breaks=1:4) + scale_colour_hue(breaks='A', labels='label A')+ scale_colour_hue(breaks='B', labels='label B') How can I keep the grey scale, but avoid changi...

Hi all, I'm interested in doing a dot plot where *both* the size and color (more specifically, shade of grey) change with the associated value. I've found examples online for ggplot2 where you can scale the size of the dot with a value: http://had.co.nz/ggplot2/graphics/6a053f23cf5bdfe5155ab53d345a5e0b.png Or scale the color with the value:
