A bar graph or bar chart displays categorical data with parallel rectangular bars of equal width along an axis. In this tutorial, we will learn how to plot a standard bar chart/graph and its other variations like double bar chart, stacked bar chart and horizontal bar chart using the Python library Matplotlib. df.plot(kind="bar", stacked=True) gives us this chart: We can add a 'total' line similar to the black line in the question's image by summing the rows of the data frame and plotting the returned Series object on the same axes as the bar chart: The code that generated this second chart is below. Matplotlib - Bar Plot A bar chart or bar graph is a chart or graph that presents categorical data with rectangular bars with heights or lengths proportional to the values that they represent.

In other words we have to take the actual floating point numbers, e.g., 0.8, and convert that to the nearest integer, i.e, 1. In this post, we will see how we can plot a stacked bar graph using Python’s Matplotlib library. A stacked bar graph also known as a stacked bar chart is a graph that is used to break down and compare parts of a whole. Stacked Bar Graphs place each value for the segment after the previous one. The total value of the bar is all the segment values added together.
