Overview of this book

Python is a multi-domain, interpreted programming language. It is a widely used general-purpose, high-level programming language. It is often used as a scripting language because of its forgiving syntax and compatibility with a wide variety of different eco-systems. Python GUI Programming Cookbook follows a task-based approach to help you create beautiful and very effective GUIs with the least amount of code necessary. This book will guide you through the very basics of creating a fully functional GUI in Python with only a few lines of code. Each and every recipe adds more widgets to the GUIs we are creating. While the cookbook recipes all stand on their own, there is a common theme running through all of them. As our GUIs keep expanding, using more and more widgets, we start to talk to networks, databases, and graphical libraries that greatly enhance our GUI’s functionality. This book is what you need to expand your knowledge on the subject of GUIs, and make sure you’re not missing out in the long run.

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 often plot charts from very 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, and it will get you started (and then you can have a lot of fun creating GUIs, charts, and so on, using Python).

How to do it…

Modify the yValues1 line of code from the previous recipe to use 50 as the third value:

Matplotlib_labels_two_charts_not_scaled.py

    axis  = fig.add_subplot(111)        # 1 row, 1 column 
    xValues  = [1,2,3,4] 
    yValues0 =...
