Part: III MORE COOL WEB APPLICATIONS > CREATING DYNAMIC GRAPHS IN ZOPE

Chapter 11. CREATING DYNAMIC GRAPHS IN ZOPE

In this chapter, you will learn something about PIL, the Python Imaging Library, which will help you create dynamic graphs in Zope. After the general introduction to PIL, we will come back to the Poll product that was introduced in Chapter 10, “Adding Search Capabilities,” and see how PIL is used there to create a pie chart of a poll question's votes. In the last section of this chapter, we will develop a method that will allow us to also create bar graphs for the question's votes.

This chapter will only deal with a small part of PIL. If you want to learn more about it, you can download the PIL Handbook from http://www.pythonware.com/library/index.htm or browse it at http://www.pythonware.com/library/pil/handbook/index.htm.
