In this chapter, we will cover:
In this chapter, we will learn how to make various types of heat maps and contour plots. By heat maps, we mean color coded grid images, useful for visualizing correlations, trends and multivariate data. We will see how contour plots can be used to show topographical information in various two-dimensional and three-dimensional ways.
The recipes in this chapter are a bit longer and more advanced than the ones in previous chapters. However, the code is clearly explained step by step, so that you can understand how it works.
As with the previous chapters, it is best to try out each recipe first with the example shown here and then with your own datasets so that you can fully understand each line of code.
