Chapter 9. Visualizing Multi-Dimensional Data in Scala

In this chapter, we will build on what you learned in the previous chapter and teach you how to use the advanced features of JFreeChart to visualize multi-dimensional data. Multi-dimensional or multi-variant data is data where separate objects, events, and so on, are described using several numerical attributes. If the number of attributes is lower than four, then visualizing this data is relatively simple.

One can use a scatter plot or its 3D equivalent. Then, one can look at the plotted data to visually ascertain its structure. If the dataset describes objects belonging to several distinct classes, for example, the relationship between the classes can be visually determined by a human analyst. ...
