Highcharts 3 suppor for Android 2.x

view story

http://stackoverflow.com – Has anyone tried using the latest Highcharts 3.0 beta (Mar 2013) with a phone running Android 2.x (specifically 2.3)? When I try rendering any of the demo charts from that blog post or using that library inside a WebView, I get nothing. Seems to work perfectly fine in Android 4.x. I changed the library to HC 2.3.5 and the charts are now visible. I this because the canvas library does not support HC 3? What's the story? (HowTos)
