I am using FusionCharts for JavaScript / HTML5 (No Flash). All charts are load well except for the Scatter chart which seems to be taking long. I want to know if this is a known issue for this particular chart type and software version. The parameters needed to query the database and feed the chart (and load it using Ajax) are not known at page load time so the Scatter chart is loaded later on an isolated click event making the Ajax call. Is there a documented performance issue with the scatter chart that I need to know about? Thanks for any replies.
