Highcharts Gauge chart: Fiat 500 Speedometer
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.
