#PLOT MULTIPLE DATAFRAMES ON ONE GRAPH R HOW TO#
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 You can use the following methods to plot multiple plots on the same graph in R:
