Matplotlib Tutorial | How to graph a Grouped Bar Chart (Code included)

[ad_1]

In this Matplotlib for Pyhton exercise, I will be showing how to create a grouped bar graph using the matplotlib library in Python. (It has been a long time since I create a tutorial video for matplotlib, there are quiet many terms I don’t even recall. I am might have to remake the tutorial again with the same content).

Points to take away
– We will learn how to add data label (data label annotation)
– We will learn how to insert custom labels for X and Y axis.
– We will learn how to insert a legned

I managed to plot the graphs by modifying your code to fit my data set. However the legend cannot be created due to "No handles with labels found to put in legend". =(
