The above sample showcases how to start automatic server-side export. It does not save the exported file until you define proper export handler before testing all the features of this example. We've provided ready-to-use server-side export handlers in multiple programming languages like ASP.NET, PHP, J2EE and Ruby on Rails. Depending on what technology you're using, you can copy-paste the relevant files from Download Package > ExportHandlers folder to your web server. You'll need to provide the path of the export handler in the exportHandler attribute of the XML data for the chart.
