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.

Draw ggplot2 Plot with Two Y-Axes in R (Example) | Different Scale on Each Side. In this R programming tutorial you’ll learn how to return a ggplot2 graph with 2 y-axes and different scales on each side. Table of contents: 1) Creation of Example Data.
20 maj 2022 · A brief tutorial on plotting two y-axes in ggplot. May 20, 2022. Setting the Scene. Goal. Generate the PKPD data. Creating the Dual Axis Plot. Automatically defining the scaling function. Bonus: Styling the Secondary Y axis. Setting the Scene. You have collected data on two variables, both changing with time.
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:
Add the dual axis. This needed a bit of jiggery-pokery to get the second axis on a reasonable scale. If you haven’t done this before, you define that you want a secondary axis with the sec_axis argument to scale_y_continuous. You will need to transform it - here I am telling it to divide the value by 10,000.
On this page you’ll learn how to draw a plot with two y-axes using the ggplot2 package in R programming. Preparing the Example. data (iris) # Loading example data. head (iris) # Sepal.Length Sepal.Width Petal.Length Petal.Width Species.
