Hi all,
 
I've this ggplot2 graph
(http://www.4shared.com/file/120101043/f3e9350/isotherm.html).
 
I'd like to tweak the legend for the adsorbent part. I'd like to have full
square of the colors instead of the full circles.
I guess that I've to work on the scale_color_hue or fill somewhere but I
haven't found my way yet.
 
Here is my code to get the graph:
 
pdf("isotherm.pdf",width=7,height=6)
 
#windows(width=7,height=6)
ads.graph<-ggplot(Adsorp.DATA,aes(relative.p,ads.vol,shape=type
   ,color=adsorbent))+
 
 geom_point(size=I(3)) +
 
 labs(x=expression(p/p[0]),y=N[2]~adsorbed~volume~(cc/g)) +
 
 scale_shape(name="Adsorption\nProcedure"
  ,solid=F
  ,breaks=c("A","D")
  ,labels=c("Adsorp.","Desorp.")
  ) +
 
 scale_colour_hue(name="Adsorbent") +
 
 scale_x_continuous(limits=c(0,1),minor_breaks = seq(0,1,0.1)) +
 scale_y_continuous(limits=c(0,1000)) +
 
 opts(panel.grid.minor = theme_line(colour = "grey94"))
 
print(ads.graph)
dev.off()
 
 

Regards/Cordialement
