Because the range is so different between the two series, I'd suggest
using log="y", ylim=c(500,2)

Let me give you an analogy:

Hi,
If he wants the two sets of data plotted on the same y axis scale, with the
range of the y axis adjusted to the data, an alternative to the use of plot()
and points() is:
matplot(Date, cbind(MORTSFr, MORTSBu), type = "l")
See ?matplot

... which is exactly what he shouldn't do because now it the plot falsely
asserts that both curves are plotted to the same scale.

Here is how:
plot(Date,MORTSFr,type="l", ylim=c(0,max(MORTSFr)))
points(Date,MORTSBu,type="l",lty=2)
If you don't use the same scale for the two plots, you are probably
misrepresenting the data. If you want to plot relative change, normalize the
data before plotting.
norm <- function(x) {(x -
Dear R-Experts,
I try to superimpose/present 2 curves/plots on the same graph. I would like the
result/graph to be readable.
For that, I use the par(new=TRUE) argument but on the Y-axis there is a
superposition of writings and the Y-axis becomes unreadable.
How can I solve this problem ?
