Hi,
I want to plot two variables on the same graph but with two y axis just
like what you can do in Excel. I searched online that seems like you can
not achieve that in ggplot. So is there anyway I can do it in a nice way in
basic plot?
Suppose my data looks like this:
Weight Height Date
0.1 0.3 1
0.2 0.4 2
0.3 0.8 3
0.6 1 4
I want to have"Date"as X axis ,"Weight" as the left y axis and "Height" as
the right y axis.
Thanks.
