Matplotlib for Python Developers

Overview of this book

Providing appealing plots and graphs is an essential part of various fields such as scientific research, data analysis, and so on. Matplotlib, the Python 2D plotting library, is used to produce publication-quality figures in a variety of hardcopy formats and interactive environments across platforms. This book explains creating various plots, histograms, power spectra, bar charts, error charts, scatter-plots and much more using the powerful Matplotlib library to get impressive out-of-the-box results. This book gives you a comprehensive tour of the key features of the Matplotlib Python 2D plotting library, right from the simplest concepts to the most advanced topics. You will discover how easy it is to produce professional-quality plots when you have this book to hand. The book introduces the library in steps. First come the basics: introducing what the library is, its important prerequisites (and terminology), installing and configuring Matplotlib, and going through simple plots such as lines, grids, axes, and charts. Then we start with some introductory examples, and move ahead by discussing the various programming styles that Matplotlib allows, and several key features. Further, the book presents an important section on embedding applications. You will be introduced to three of the best known GUI libraries 'GTK+, Qt, and wxWidgets' and presented with the steps to implement to include Matplotlib in an application written using each of them. You will learn through an incremental approach: from a simple example that presents the peculiarities of the GUI library, to more complex ones, using GUI designer tools. Because the Web permeates all of our activities, a part of the book is dedicated to showing how Matplotlib can be used in a web environment, and another section focuses on using Matplotlib with common Python web frameworks, namely, Pylons and Django. Last, but not least, you will go through real-world examples, where you will see some real situations in which you can use Matplotlib.

Matplotlib and Django

Django is a very well-known Python web framework. Let's first introduce it and then present the example.

What is Django

Django grew from a practical need: create a framework for building intensive web applications for journalism or news web sites.

As Django was born in the news environment, it offers several features which are particularly well suited for content web sites. Although Django is particularly good for developing those sorts of sites, that doesn't preclude it from being an effective tool for building any kind of dynamic web site.

Moreover, it's a common misinterpretation that Django is a Content Management System (CMS); well, it is not. It's a web framework, a programming tool, as well as something that we can use to create a CMS.

Django changes the MVC pattern slightly; in its interpretation:

  • The view describes the data that gets presented to the users (not necessarily how the data will be presented, but which data to present). This is basically a Python...
