Matplotlib for Python Developers - Second Edition

By: Aldrin Yim, Claire Chung, Allen Yu

Overview of this book

Python is a general-purpose programming language increasingly being used for data analysis and visualization. Matplotlib is a popular data visualization package in Python used to design effective plots and graphs. This is a practical, hands-on resource to help you visualize data with Python using the Matplotlib library. Matplotlib for Python Developers, Second Edition shows you how to create attractive graphs, charts, and plots using Matplotlib. You will also get a quick introduction to third-party packages, Seaborn, Pandas, Basemap, and Geopandas, and learn how to use them with Matplotlib. After that, you’ll embed and customize your plots in third-party tools such as GTK+3, Qt 5, and wxWidgets. You’ll also be able to tweak the look and feel of your visualization with the help of practical examples provided in this book. Further on, you’ll explore Matplotlib 2.1.x on the web, from a cloud-based platform using third-party packages such as Django. Finally, you will integrate interactive, real-time visualization techniques into your current workflow with the help of practical real-world examples. By the end of this book, you’ll be thoroughly comfortable with using the popular Python data visualization library Matplotlib 2.1.x and leveraging its power to build attractive, insightful, and powerful visualizations.

Chapter 6. Embedding Matplotlib in Qt 5

There are several GUI libraries available, and one widely used library is Qt. In this book, we will be using Qt 5, the latest major version of this library. Unless explicitly mentioned, we are referring to Qt 5 when we simply state Qt throughout the chapter.

We will follow a similar progression to that in Chapter 5, Embedding Matplotlib in GTK+3, and we will present similar examples but this time written in Qt.

We believe that this method will allow us to directly compare the libraries, and it has the advantage of not leaving the How would I write something with library X? question unanswered.

In this chapter, we will learn how to:

  • Embed a Matplotlib figure into a Qt widget
  • Embed a figure and navigation toolbar into a Qt widget
  • Use events to update a Matplotlib plot in real time
  • Use QT Designer to draw a GUI and then use it with Matplotlib in a simple Python application

We will begin by giving an introduction to the library.
