![]() ![]() Here is an example of how to plot multiple lines in one chart using ggplot2. #add a legend in top left corner of chart at (x, y) coordinates = (1, 19) #add third data series to the same chart using points() and lines() #add second data series to the same chart using points() and lines() The code below demonstrates an example of this approach: #generate an x-axis along with three data series ![]() Legend("topright", legend = 1:3, col=1:3, pch=1)Īnother way to plot multiple lines is to plot them one by one, using the built-in R functions points() and lines(). #plot the three columns of the dataset as three lines and add a legend in #the top right corner of the chart #numbers from a uniform distribution with minimum = 1 and maximum = 10 圓 points (x2, y2) The following examples show how to use each of these functions in practice. y2 lines (x2, y2) overlay scatterplot of x3 vs. y1 plot (x1, y1) overlay line plot of x2 vs. If you have a dataset that is in a wide format, one simple way to plot multiple lines in one chart is by using matplot: #Create a fake dataset with 3 columns (ncol=3) composed of randomly generated Learn how to plot a single chart that displays several datasets in R with Eugene O'Loughlin.The R script (38HowToCode.R) and data file (38DataFile.csv). You can create multiple plots on the same page (plotting environment) using the command par(mfrow(m, n)), where m is the number of rows and n is the number. You can use the lines () and points () functions to overlay multiple plots in R: create scatterplot of x1 vs. Here are two examples of how to plot multiple lines in one chart using Base R. To plot multiple lines in one chart, we can either use base R or install a fancier package like ggplot2. This tutorial explains how to plot multiple lines (i.e. ![]()
