Dear all,

meanwhile i found out how to handle the coordinate thing and plot the  
lines like i like.
the remaining problem is, i need something like names.arg does in  
barplot for my plot.

my plot connects several dots with several lines. and now i like  
characters as the names of the intersects of the x-axis.


vector1=c(a,b)
vector2=c(c,d)

# this vector makes sure the yellow line starts at x=2
x=c(2,3)

plot(vector,type="b",col="blue",xlim=c(1,4),ylim=c(20,150))
lines(x,fc,col="yellow")

does anybody know how to label the x-axis  1st quarter 2nd quarter  
3rd quarter and 4th quarter instead of 1.0 1.5 2.0 2.5 and so on ??

thx in advance !

matthias
