If you have any issues or questions using this extension, please go to github and submit a question.
The Highcharts Extension (v2.0) for ExtJs 4.1 is here in the github. It has a lot of major features:
– Support Highcharts 2.3: Gauge, Polar and Range charts
– Support animation for all the charts: initial, update and line shift.
– A lot of optimisation is done.
PS: More documentation to come.
While I was writing up a survey for running Highcharts on the server side which accounts for 3 approaches:
- Xvfb + web browser on server side (Unix only)
- Rhino + Env.js (Java solution)
This is to show off why you should use Highcharts. The Highcharts 2.3 supports the amazing gauge charts. At first, I don’t know whether Highcharts is flexible and powerful enough but I give it a go anyway to plot a Fiat 500 speedometer. After spending nearly half a day, it is possible. You can try this with jsFiddle. Hat off to Highcharts.
The cool design of Fiat 500 speedometer is actually a perfect fit to test drive the gauge chart because it includes two dials on the same gauge, multiple backgrounds, multiple panes, plotBands in pane, dataLabels background, multiple axes, etc.
Sorry, I don’t have time to write up how I did it but will do so.
