In this chapter we learned the very basics of Ext JS, which is a framework for building Rich Internet Applications (RIAs). A quick introduction was given on a dozen Ext JS components that are likely to be used with the Highcharts extension for Ext JS. Then we explored how to create a Highcharts component from an existing Highcharts configuration in a step-by-step approach. We looked into the small set of APIs, which provided the extension module, and built a simple application with network usage data. Finally, we took a brief look at Highcharts and Ext JS applied on a commercial network monitoring application.
In the next chapter we will explore how to run Highcharts on the server side.
