![]() Note that we used the mar argument to specify the (bottom, left, top, right) margins for the plotting area. #define plotting area as two rows and one column The following code shows how to use the par() argument to plot multiple plots stacked vertically: #define data to plot Example 3: Create Multiple Plots Stacked Vertically Note that we used the ylim() argument in the second plot to ensure that the two plots had the same y-axis limits. #define plotting area as one row and two columns The following code shows how to use the par() argument to plot multiple plots side-by-side: #define data to plot Plot(x, y1, type=' l', col=' red', xlab=' x', ylab=' y')Įxample 2: Create Multiple Plots Side-by-Side The following code shows how to plot two lines on the same graph in R: #define data to plot Example 1: Plot Multiple Lines on Same Graph The following examples show how to use each method in practice. Method 3: Create Multiple Plots Stacked Vertically #define plotting area as two rows and one column Method 2: Create Multiple Plots Side-by-Side #define plotting area as one row and two columns Method 1: Plot Multiple Lines on Same Graph #plot first line A complete list of properties and attributes can be found on the the ggplot2 webpage.You can use the following methods to plot multiple plots on the same graph in R: There are a wide range of additional properties that can be modified in the ggplot2 package including chart and axis titles, borders, grid lines, legend, etc. Adding the title, removing axis labels, and removing a lot of the default theme.Adding data labels and colors - supplied as hex codes.Converting it to polar coordinate system to make it round. ![]() In the code above I have broken up the stages across multiple lines to help with readability, but you can typically do it all on one line The code above builds the pie chart by: You can sequence functions for modifying the plot by "adding" them, by which I mean a "+" sign is used to separate the different function calls. I've generated this pie chart with a specified custom color palette. Pie = pie + theme_classic() + theme(axis.line = element_blank(), Pie = pie + labs(x = NULL, y = NULL, fill = NULL, title = "Phones - Market Share") Pie = pie + coord_polar("y", start=0) + geom_text(aes(label = paste0(round(value*100), "%")), position = position_stack(vjust = 0.5)) # Convert to pie (polar coordinates) and add labels ![]() Pie = ggplot(df, aes(x="", y=share, fill=brand)) + geom_bar(stat="identity", width=1) Creating a Pie Chartįirst we'll load the ggplot2 package and create a bar chart using the geom_bar function. Next, we'll use this data frame to create the pie chart using the ggplot2 package. For this example, we'll use some sample data showing global market share for mobile phone manufacturers.ĭf = ame("brand" = c("Samsung","Huawei","Apple","Xiaomi","OPPO","Other"), We first create a data frame containing the values that we want to display in the pie chart. Adding DataĪll you need for a pie chart is a series of data representing counts or proportions, together with the corresponding labels. In this post, we'll show how to use this package to create a basic pie chart in R. One of the more popular packages used today is the ggplot2 package. There are various packages available for creating charts and visualizations in R. Pie charts are the classic choice for showing proportions for mutually-exclusive categories. ![]()
