Python GUI Programming Cookbook - Third Edition

By: Burkhard Meier

Overview of this book

Python is a multi-domain, interpreted programming language that is easy to learn and implement. With its wide support for frameworks to develop GUIs, you can build interactive and beautiful GUI-based applications easily using Python. This third edition of Python GUI Programming Cookbook follows a task-based approach to help you create effective GUIs with the smallest amount of code. Every recipe in this book builds upon the last to create an entire, real-life GUI application. These recipes also help you solve problems that you might encounter while developing GUIs. This book mainly focuses on using Python’s built-in tkinter GUI framework. You'll learn how to create GUIs in Python using simple programming styles and object-oriented programming (OOP). As you add more widgets and expand your GUI, you will learn how to connect to networks, databases, and graphical libraries that greatly enhance the functionality of your GUI. You’ll also learn how to use threading to ensure that your GUI doesn't become unresponsive. Toward the end, you’ll learn about the versatile PyQt GUI framework, which comes along with its own visual editor that allows you to design GUIs using drag and drop features. By the end of the book, you’ll be an expert in designing Python GUIs and be able to develop a variety of GUI applications with ease.

Scaling charts

In the previous recipes, while creating our first charts and enhancing them, we hardcoded the scaling of how those values are visually represented.

While this served us well for the values we were using, we might have to plot charts from large databases.

Depending on the range of that data, our hardcoded values for the vertical y-dimension might not always be the best solution, and may make it hard to see the lines in our charts.

Getting ready

We will improve our code from the previous recipe, How to give the chart a legend. If you have not typed in all of the code from the previous recipes, just download the code for this chapter from the Packt website, and it will get you started (and then you can have a lot...
