[R] Over lay 2 scale in same plot

[Joshua Wiley]

Hi,

Looking at the picture, I think you are just talking about plotting
two datasets.  Here is an example I made up, that looks sort of like
your picture:

# make a barplot
barplot(-50:50)
# add points into the existing plot at the coordinates set by x and y
# and use a line to connect them
points(x = 1:101, y = seq(from = 30, to = -20, length.out = 101), type = "l")

Do you have some sample data you could send us of what you are trying
to plot?  We can give more specific feedback if we have some actual
data to work with.

Hope that helps,

Josh
