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.

If you are already familiar with REST theory but are new to RESTful
Java web services, and want to use the Java technology stack together
with Java RESTful frameworks to create robust web services, this is the
book for you.
This book is a guide to developing RESTful web services using Java and the most popular RESTful frameworks available today. It covers the theory of REST; practical coding examples for RESTful clients; a practical outline of the RESTful design process-yes, it's different from traditional web application development; and a complete implementation of a non-trivial web service using the following frameworks: Jersey's JAX-RS, Restlet's Lightweight REST, JBoss's JAX-RS RESTEasy, and Struts 2 with the REST plug-in.
We begin with an introduction to REST theory, for example, what it means for a web service to be RESTful, what it means for a web service to exchange representations of resources, and what it means to only use the conventional HTTP request method types-GET, POST, PUT, DELETE-for client/server communication. Before moving into the design and implementation process of a non-trivial web service, we look at a set of sample Java applications that connect to existing REST services that are freely available (Google, Yahoo, Twitter). We then outline a practical design process for RESTful web services and then cover the four most widely used frameworks available to date: JAX-RS implementations such as Jersey and RESTEasy, the Restlet framework, and Struts 2 with the REST plug-in. We cover each framework in detail to allow you to compare the strengths and weaknesses of each framework and to begin developing your own web services after the first reading; what's more, the whole source is included for you to modify and deploy in your own web services. Finally, we discuss the most common performance issues faced by RESTful web services and cover practical solutions to security-related issues such as authentication and data transfer.
