It is possible to initiate an export from PHP on the server? Based on my research I am thinking it is not because the export uses the rendered chart on the client side.
But hopefully - maybe I am wrong and you can export to an image without getting the client side involved?
Assuming you can't initiate the export from the server then am I on the right track with this:
Goal: Transparently to the user, create a PDF with numerous (up to 16) pie charts on it
Environment: hosted MS_SQL database with several million rows
Approach:
Use PHP to create the page with all the charts embedded
Include the necessary JavaScript in the page
In the on-load JavaScript:
for each chart, verify it has rendered then export it to a unique filename that includes a unique session ID [examples: sessionID1chart1.jpg, sessionID1Chart2.jpg, etc...)
open a PHP page passing it the session ID which creates the PDF using the saved jpg files
I am evaluating FusionCharts and think it is what I will end up using but am concerned about the difficulty of accomplishing this task.
Any help and advise would be appreciated.
Thanks!
