Hi,
What determines the order of the rows in a barchart?
Cheers,
Geoff.
Here is my code, and the data follows. If I have z in alpha order, the
barchart is in
some order I can't determine. I originally tried
rownames(twater)~twater$Cat, but the
chart wasn't in rownames(twater) order either.
library(lattice)
twater<-read.csv("totalwater.csv",strip.white=T)
twater$Cat<-ordered(twater$Cat,levels=(sort(levels(twater$Cat))))
sel<-twater$Cat=="A"
nm<-sort(rownames(twater))
z<-factor(nm,levels=nm)
chart<-barchart(z~twater$Volume,
xlab="Volume of Water '000 ML",
main="Water Use In Australia for Food",
scales=list(col='dark green',
cex=1.2,
fontface='bold',
),
panel=function(x,y) {
panel.barchart(x[!sel],y[!sel],col='blue')
panel.barchart(x[sel],y[sel],col='red')
})
pdf("Rplot-totalwater.pdf",height=4)
plot(chart)
dev.off()
