Now, we can apply the ggplot function in combination with the geom_line function to draw a line graph with the ggplot2 package: ggplot(data, aes(x=x, y=y, col=line))+# Draw line plot with ggplot2geom_line() Figure 8: Create Line Chart with ggplot2 Package. Figure 8 is showing h...
This R graphics tutorial describes how to change line types in R for plots created using either the R base plotting functions or the ggplot2 package.

This post is a step by step introduction to line chart with R and ggplot2. It provides several reproducible examples with explanation and R code.
In base R, theline functionallows to build quality line charts. Dual Y axis withggplot2 Warning: a dual Y axis line chart represents the evolution of 2 series, each plotted according to its own Y scale. This kind of chartmustbe avoided, since playing with Y axis limits can lead to com...
Given a data frame in long format like df it is possible to create a line chart with multiple lines in ggplot2 with geom_line the following way. # install.packages("ggplot2") library(ggplot2) ggplot(df, aes(x = x, y = value, color = variable)) + geom_line() Lines width and st...
I recently had an email for a colleague asking me to make a figure like this in ggplot2 or trellis in R: As I know more about how to do things in ggplot2, I chose to use that package (if it wasn't obvious from the plot or other posts). Starting Point Coo
ggplot(EuStockDF,aes(x=Date, y=SMI))+geom_line() However, variable names are frequently insufficiently descriptive. For example, if someone were to glance at this graph, they might not know what “SMI” stands for. To modify the axis labels, use the labs() method and provide the y ax...
