Area Line Plot with Multiple Series

We can create area line plots with multiple series, each represented by a separate line and filled area. Here’s an example with two series.

R

# Create data with multiple series
set.seed(789)
df_multiple_series <- data.frame(
  Year = 2000:2020,
  Series1 = cumsum(rnorm(21)),
  Series2 = cumsum(rnorm(21))
)
 
# Create an area line plot with multiple series
ggplot(df_multiple_series, aes(x = Year)) +
  geom_area(aes(y = Series1, fill = "Series 1"), alpha = 0.5) +
  geom_area(aes(y = Series2, fill = "Series 2"), alpha = 0.5) +
  labs(
    title = "Area Line Plot with Multiple Series",
    x = "Year",
    y = "Cumulative Value"
  ) +
  scale_fill_manual(values = c("Series 1" = "blue", "Series 2" = "red")) +
  theme_minimal()

Output:

Area Line Plot in R

In this example, we create an area line plot with two series (Series 1 and Series 2). Each series is represented by a separate line and filled area. We use the alpha argument to control the transparency of the filled areas. The scale_fill_manual function is used to specify custom fill colors for the two series.

Area Line Plot in R

Area line plots, commonly referred to as filled area plots, are effective data visualisation techniques in R for showing how data evolves over time. They are particularly helpful for displaying trends, distributions, and time series data. In this article, we’ll look at how to use the well-liked ggplot2 programme to generate area line plots in R.
