- 2. Presentation title 2 www.cic.vic.edu.au Youcan use server-side code to acquire data to populate your chart. Your server-side code can load a local file, query a database, or get the data in some other way. The following PHP example demonstrates reading chart data from a local text file when a page is requested. You can copy these files to your own server, if it supports PHP.
