I have been comparing many chart framework, and these two are the final contenders. There is no point to compare frameworks if there are no specifications. So, I will lay down my specifications and hope to have some responses, would be valuable to people having questions on which framework they should choose.
Final Goal : Stock Chart just like Google Finance Points of interest 1. No Flash, for mobile device compatibility 2. No Charge (HighCharts is cool if you have money) 3. Annotation on Chart, for marking events 4. Zoom in/ Zoom out 5. Multiple Y-axes
Where do you think?
