27 maj 2019 · Answer recommended by R Language Collective. Starting with ggplot2 2.2.0 you can add a secondary axis like this (taken from the ggplot2 2.2.0 announcement): ggplot (mpg, aes (displ, hwy)) + geom_point () + scale_y_continuous ( "mpg (US)", sec.axis = sec_axis (~ . * 1.20, name = "mpg (UK)") ) edited Jul 21, 2018 at 16:34.

A good use for dual axis charts (possibly the only really good one) is for Pareto charts. A pareto chart combines both the count of an item, and the percentage contribution that count makes to the overall tally.
The Solution 🎉. Fortunately, there is a way to overcome this hurdle and have separate y-axes for each layer of your combined chart. 📈 Here's how you can achieve that: Step 1: Load the Required Packages 📦. To begin with, make sure you have the necessary packages installed. We'll be using ggplot2, so let's load it: library(ggplot2)

13 mar 2022 · Create Pareto charts in ggplot2 with custom legends using manual scales and ggtext. I had to produce a dual axis chart as part of a piece of work transitioning an Excel report to markdown. I thought I’d do a walkthrough of a chart that is similar in style, but different in content than the one I produced at work.
