Real-Time Smooth Scrolling
While Highcharts Stock supports dynamically updated data, the new data points are applied in a jerky fashion. It's becoming easier to build real-world real-time data applications: it'd be great if HighCharts Stock could handle these updates in a smoother fashion (similar to Smoothies http://joewalnes.com/2010/08/10/introducing-smoothie-charts/).
You mean like we do in Highcharts: http://www.highcharts.com/demo/dynamic-update.
The Highstock charts generally consist of much more data, so currently we have disabled animation because it didn’t perform good enough.
I'm a mathematician I want to post-process stock data in real-time from commercial feeds and chart it. Is there any application which uses real charts available. I want to add any of my indicators to any Stock chart and automate trades.
Whenever I update the data dynamically in highstock, it completely forgets the state of the Scrollbar and Navigator... :/ Any help appreciated.
Mike, this is strictly off topic, but Highcharts does animate on pie slice update. See http://jsfiddle.net/highcharts/Qv7sW/.

Great - really helpful -
How about animating between user initiated pie updates? Such as you might see on a dashboard or controls on an infographic
Thanks for the pointers! Working with the dynamic update example, if I (1) reduce the number of data points (2) enable animation and (3) decrease the update interval to around 100ms (real-time), it does in fact behave smoothly.
It's completely reasonable to expect poor performance with many data points. I'd ignore this suggestion.
