Example
A simple line chart is created using the input vector and the type parameter as "O". Let's create a rainfall line chart for
Delhi in six months of effective rain as per data of 2020:
Month Apr May June July Aug Sep
Rainfall in mm 30 29 54 217 248 134
The below script will create and save a line chart in the current R working directory.
# Create the data for the chart.
v <- c(30, 29, 54, 217, 248, 134)
# Give the chart file a name.
png(file = "line_chart.jpg")
# Plot the bar chart.
plot(v,type = "o")
# Save the file.
dev.off()
When we execute the above code, it produces the following result:
Line Chart using R
7.6.1 line chart with title, colour and labels
The features of the line chart can be expanded by using additional parameters. You can add colour to the points and
lines, give a title to the chart, and add labels to the axes.
