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. The bars can be plotted vertically or horizontally. A bar graph shows comparisons among discrete categories.
Write a program to plot a stacked bar graph with two values for comparison, using different colors using matplotlib.pyplot library. Submitted by Ayush Sharma, on November 19, 2018 Problem statement: Write a program in python (using matplotlib.pyplot) to create a scatter plot. Matplotlib: Bar Graph/Chart. A bar graph or bar chart displays categorical data with parallel rectangular bars of equal width along an axis.

For the third bar chart, we have to compute the bottom values as A + B, the coefficient-wise sum of A and B. Using NumPy helps to keep the code compact but readable. This code is, however, fairly repetitive and works for only three stacked bar charts. We can do better using the following code:
I'm using matplotlib's stacked bar graph example with a couple of issues. Can you please help me understand why my code is not stacking the values appropriately?

Often the data you need to stack is oriented in columns, while the default Pandas bar plotting function requires the data to be oriented in rows with a unique column for each layer. Below is an example dataframe, with the data oriented in columns. Stacked bar charts are of course possible by using a special parameter from the pyplot.bar() function.
