In this chapter, we studied the Highcharts APIs, from the class model to applying them in applications. Then we performed a comprehensive study of the different techniques for updating a chart series in Highcharts, and carried out an experiment to analyze the difference in their performance. Finally, the chapter finished by analyzing the speed of different web browsers when rendering data points with regard to different sizes of large datasets.

In the next chapter, we will look into Highcharts events handling, which is closely related to Highcharts APIs.
