There's a new article on the Customization Articles page on how to add single series charts to pages using the FusionCharts files that can be found in the /flash folder on the PowerSchool server.  The article can be found in the Customizing PowerSchool - Intermediate area and includes a plugin that can be installed that will display a bar chart of enrollment by grade levels.  The article uses the page as a reference point for the coding, so even if you don't install the plugin, you'll want to download it and view the html of the page in it to follow the article.

Thanks,

Matt
