![]() For that reason, we first have to use the reshape2 package to convert our data frame from wide to long format. The ggplot2 package typically takes long data as input. #Two plots on one graph r how to#In Example 2, I’ll show how to plot multiple time series to a graph using the ggplot2 package in R. Lines(data$year, # Draw third time seriesĪs shown in Figure 1, we created a time series graphic containing multiple lines with the previous syntax.Įxample 2: Drawing Multiple Time Series Using ggplot2 Package Lines(data$year, # Draw second time series You can use the following methods to plot multiple plots on the same graph in R: Method 1: Plot Multiple Lines on Same Graph. Legend ( "topright", # Add legend to plot ![]() Lines (data$year, # Draw third time series Lines (data$year, # Draw second time series Parameter 2 specifies points on the y-axis. Parameter 1 specifies points on the x-axis. The function takes parameters for specifying points in the diagram. The Introduction to R curriculum summarizes some of the most used plots, but cannot begin to expose people to the breadth of plot options that exist. > Hi Chris, In order to get the zeros of the two abscissae at the same horizontal point, you will have to make both symmetric. Plot (data$year, # Draw first time series The plot () function is used to draw points (markers) in a diagram. Can anyone suggest how you would get the two graphs to line up I think you > have to set a ratio between the two sets of axes so that the origin is in > the centre but I don't know how to do it. More precisely, we have to use the plot, lines, and legend functions as follows: Case 2: Extra graph specified We will specify that 4 plots need to be combined in 2 rows and 2 columns but specify 6 graphs instead of 4. mat <- matrix(c(1, 2, First, second 1, 3), first and third plot nrow 2, ncol 2, byrow TRUE), layout(mat mat, widths c(1, 2)) First and second column relative widths Data set.seed(6) x <- rexp(50) plot(x) First column, top boxplot(x) First. Case 1: Lesser number of graphs specified We will specify that 4 plots need to be combined in 2 rows and 2 columns but provide only 3 graphs. In Example 1, I’ll illustrate how to draw a graph showing multiple time series using the basic installation of the R programming language. Example 3: two columns, with two plots on the right and one on the left, being the second column two times wider than de first. The variable year defines the time range and the variables ts1, ts2 and ts3 contain the corresponding values of three different time series.Įxample 1: Drawing Multiple Time Series in Base R The previous output of the RStudio console shows that our example data has four columns. ![]() seed ( 1023172 ) # Create random example dataĭata <- round (data. ![]()
