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.
