Chapter 8. Waterfall, Funnel, Pyramid, and Heatmap Charts
In this chapter, we explore some of the more unusual charts, such as waterfall and funnel charts, by using simple sales and accounting figures. We experiment with how we can link both the charts together with related information. Then, we move on to investigate how to plot a pyramid chart and assess the flexibility of Highcharts by imitating a financial pyramid chart from a proper commercial report. Finally, we study the heatmap chart and tweak various specific options with real-life statistics in a step-by-step approach. In this chapter, we will cover the following topics:
Constructing a waterfall chart
Making a funnel chart
Joining both waterfall and funnel charts
Plotting a commercial pyramid chart
Exploring a heatmap chart with inflation data
Experimenting with the dataClasses and nullColor options of a heatmap chart
