Re: [R] Secondary y axis in ggplot2: did not respond when change its y-axis value

The second y-axis in ggplot2 is only intended to relabel an axis with a fixed transformation. E.g. one axis in degree Celcius and one in Kelvin, km and miles, ... It does not rescale the variables. It looks like you want to display two variables with unrelated units on the same y-axis. That is not

Re: [R] Secondary y axis in ggplot2: did not respond when change its y-axis value

Hello, What about the following? First get the min and max of value by variable == "y1". Then use that range to scale up "y2". rng <- tapply(daT1$value, daT1$variable, range)$y1 ggplot(data = daT1, aes(x = x, group = variable, color = variable)) + geom_line(data = subset(daT1, variable == "y1
