plotting questions

I'm having some issues with using chron() objects for the x-axis in plots.

#########
plot(chron(c("07/01/01","08/01/02")),c(100,200),cex.axis=5)
#########

It doesn't seem to scale up the cex of the x-axis.  Is there any way to scale 
these x-axis labels up?

Also, I'm not sure but I don't believe I have even seen this behavior. 

#############
plot(chron(c("07/01/01","08/01/02")),c(100,200),cex.axis=5)
points(chron(c("07/01/01","08/01/02","12/01/01")),c(100,200,150),type="b")
#############

It could be me but I think points() had always sorted the values before 
connecting the points with lines?
 
I'm working with R1.6 on Redhat 7.3(i386).
