I’ve tried to modify Joe’s patch into a plugin so that it can run without modifying Highcharts itself. The result can be seen at http://jsfiddle.net/highcharts/c42Ms/.
I didn’t have time right now to check across browsers, but I’m open for suggestions for improvements.Yuriy shared this idea ·
As Jamie says, Highcharts already supports this, you just need to loop over datasets and run Series.setData or Point.update for each step.
But we are currently working on a set of demos to demonstrate this, which will make it easier for you to set up, as you can copy-paste from our samples.
There’s a plugin for it: https://github.com/TorsteinHonsi/Motion-Highcharts-PluginYuriy supported this idea ·
