Exercise: Plot life expectancy of Brazil. ; Adding a target line or benchmark line in your graph is even simpler. Required fields are marked *. Receive updates of our latest articles via email. To make so with matplotlib we just have to call the plot function several times (one time per group). To plot a single line graph, all you need to do is to first import the matplotlib module into your Python program and then you have to use the pyplot.plot method of this module. In this plot, you will learn about how to add trend line to the line chart / line graph using Python Matplotlib. Once you have the data, youâll need to create a graph, then plot the data on the graph. Basic area. How are we going to use it to plot multiple lines on the same graph? I am trying to plot a vertical line on a XY Graph containing several unevenly sampled plots. Here I’ve also specified the label arguments for the two different lines in the plot() method.
