Version 1.2 with better support for live updating of the charts is available for public testing.
Among the new features are axis methods like setExtremes and getExtremes, series methods like addPoint, update and remove, and point methods like update and remove. All new features are listed at /ref12. Look for the words “Since 1.2.0” at the right of each member. Especially look in the event object and in the new section, Methods and Properties, at the bottom left. We expect to release the stable version in two weeks, together with updated examples and explanations in the How To.
Take a look at the general test page to inspect the new features. The code can be downloaded from this location. To compile the code, visitGoogle’s Closure Compiler and paste either the source code or the URL for the file above.
