The plt.bar creates the bar chart for us. If you do not explicitly choose a color, then, despite doing multiple plots, all bars will look the same. This gives us a change to cover a new Matplotlib customization option, however. You can use color to color just about any kind of plot, using colors like g for green, b for blue, r for red, and so on. You can also use hex color codes, like #191970. Next, we can cover histograms.

Simple Bar Charts in Matplotlib. Matplotlib’s chart functions are quite simple and allow us to create graphics to our exact specification. The example below will plot the Premier League table from the 16/17 season, taking you through the basics of creating a bar chart and customising some of its features. First of all, let’s get our modules loaded and data in place.

Matplotlib may be used to create bar charts. You might like the Matplotlib gallery. Related course. The course below is all about data visualization: Matplotlib Intro with Python. 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. Pyplot is a sub-module within matplotlib. Essentially, pyplot provides a group of relatively simple functions for performing common data visualization tasks. For example, there are simple functions for creating common charts like the scatter plot, the bar chart, the histogram, and others. matplotlib intermediate bar chart. A bar chart is a great way to compare categorical data across one or two dimensions. More often than not, it's more interesting to compare values across two dimensions and for that, a grouped bar chart is needed.

Plotting multiple bar graph using Python’s Matplotlib library import matplotlib.pyplot as plt. Second, we have to import the file which we need to visualize. data.head () Now the question comes that we want to visualize is – The GDP and Population plt.subplot (2,1,1) #The below code will create
