plot 2 y axis
Exel is hardly the epitome of good graphing. There are a couple of ways to do what you want and Jim has shown you one , but ... What about using two panels to present the data as in opar <- par(mfrow = c(2, 1)) plot(dat1$Date, dat1$Weight, col = "red", xlab = "", ylab = "Weight") plot(dat1$Date, dat1$Height, col = "blue", xlab = "Date", ylab = "Height") par <- opar John Kane Kingston ON Canada

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.
