A graphical representation is the most compact form in which to present mathematical results or the behavior of an algorithm. This chapter provided you with the basic tools for plotting and introduced you to a more sophisticated way to work with graphical objects, such as figures, axes, and lines in an object-oriented way.

In this chapter, you learned how to make plots, not only classical x/y-plots but also 3D-plots and histograms. We gave you an appetizer on making films. You also saw how to modify plots considering them to be graphical objects with related methods and attributes which can be set, deleted, or modified.
