Summary
In this chapter we learned about gauge, polar, and range charts. An extensive step-by-step demonstration showed how to plot a complex speedometer by utilizing most of the gauge options. We also demonstrated the little difference between the polar, column, and line charts with respect to principle and configuration. We used range charts to improve past chapter examples and study the subtle differences they insert into the chart. Finally, we explored how to define radial gradients by tweaking the options in stages.
In the next chapter we will explore the Highcharts APIs, which are responsible for making a dynamic chart, such as using Ajax query to update the chart content, accessing components in Highcharts objects, and exporting charts to SVG.
