Look inside

ABC Bikes Inc. is considering launching a bike rental service in your area. As the company’s data analyst, your task is to provide decision-driving insights on bike rental trends. You’ll extract the relevant data from a publicly available dataset into a pandas data frame. Then, using Python plotting library Matplotlib, you’ll create line plots to visualize changes for bike rentals on a single day as well as over a specific time period, create a grouped bar plot to visualize a comparison of renting data for two years, create subplots with different chart types, and create a violin plot to visualize renting patterns over four seasons. When you’re done, you’ll know how to use Matplotlib to create accurate and informative 2D visualizations.

This project is designed for learning purposes and is not a complete, production-ready application or solution.

book and video resources

When you start your liveProject, you get full access to the following books and videos for 90 days.

prerequisites

This liveProject is for readers interested in enhancing their data analysis capabilities with effective visualizations using Python’s Matplotlib library. To begin these liveProjects you’ll need to be familiar with the following:

TOOLS
  • Intermediate Python 3 Programming (loops, basic debugging, and built-in functions including: zip(), sorted(), and lambda functions)
  • Familiarity with Jupyter Notebook under Anaconda Distribution
  • Basic NumPy and pandas
  • Use module names to call functions
TECHNIQUES
  • Install Anaconda Distribution of Python (preferred)
  • Install/upgrade Jupyter Notebook (if not using Anaconda Distribution)
  • Install required Python Libraries (NumPy, pandas, Matplotlib, seaborn using pip or conda)
  • Add, delete, move, and select cells (code and markdown) in Jupyter Notebook
  • Execute a code cell in Jupyter Notebook

you will learn

In this liveProject, you’ll use Matplotlib to create line, bar, and violin plots to visualize trends.

  • Initialize the required style for plotting
  • Read data from a CSV file into a pandas dataframe
  • Data wrangling: subset specific rows and columns, parse date datatype
  • Group data by specific column
  • Create plots using object-oriented Matplotlib interface
  • Customize various properties of your plots: color, marker size, font size, font name
  • Format x and y axis ticks and labels for your plots
  • Change the color scheme of your plot
  • Annotate your plot with useful information
  • Set the resolution of your plots before saving
  • Export/save your plots as image files and PDF files on your hard drive with the
  • specified resolution
  • Save multiple plots in a single PDF file
  • See available plot styles and change the Matplotlib plot style for your project
  • See available backends and change the backend for Matplotlib
