Chapter 7. Highcharts APIs
Highcharts offers a small set of APIs that are aimed for plotting charts with dynamic interactions. In order to understand how the APIs work, we must first familiarize ourselves with the chart's internal objects and how they are organized inside a chart. In this chapter, we will learn about the chart classes model and how to call the APIs by referencing the objects. Then a simple stock price application is built with PHP, jQuery, and jQuery UI to demonstrate the use of Highcharts APIs. After that, we turn our attention to four different ways of updating a series. We experiment with all the series update methods with a purpose to build an application to illustrate the variation in visual effects and CPU performance between them. Finally, we investigate the performance of updating a series in terms of different sizes of datasets with popular web browsers.
