A word on how the export process works
The charts can be exported in three different formats, JPEG image, PNG image, and PDF document. Furthermore, the charts can either be exported locally at client-side or be sent to a server to be processed, or saved there. Upon initiation of the export process, the chart captures its own image in bitmap format. This bitmap image is passed on to an export component for further processing.
When exporting at client-side, the charts need to be assisted by an export component SWF to process and save the file. Charts exported at client-side add no additional load on the server. This is extremely beneficial when there are too many people exporting charts at the same time.
On the other hand, for server-side export, the exported image from the chart is processed by a server-side export component script. With this feature, the charts can be processed by the server or be saved as an image on the server for later use or for archival purposes.
