Highstock is working on ExtJs 4!! (Experimental)

Wahey!! I got Highstock working on ExtJs 4 after a full day hacking on my HighChart ExtJs 4 extension. Although HighStock shares common APIs to HighChart, the extension requires quite a few changes.

HighCharts extension for ExtJS 4

Recently, I received more emails asking me for getting the HighCharts to run on ExtJs 4. I didn’t expect anyone will be interested as ExtJs 4 comes with its own chart library. Well, here is it is.

Please read this article before using the extension. Enjoy!!

Although Highcharts currently doesn’t support Gauge/Dial chart, it is planned in the future release. However, I found there is a quick mocked up code in the feature request post with an online demo. So I have modified the code with the following features:

• display the gauge chart within a ExtJS 3 panel.
• autoscale within the panel
• add subtitle next to the gauge
• animation when value change

Currently, Highcharts (v2.1.4) doesn’t support (right click) context menu but this is in the feature request. Unfortunately, I don’t have the luxury to wait for the democratic process. So I did it the hard way and spent half a day to understand the Highcharts code and made the necessary changes to support right click context menu.
