Notes:
The chart.yRange() and chart.xRange() properties are an advanced feature. They are useful
in situations where your data has wild extremes: ie, you have lots of smaller numbers, and lots of really big numbers.<br/><br/>
Without a polylinear scale, those really big data points will overwhelm the small points.<br/><br/>
Please look at the examples to understand how polylinear scales work. Comment/uncomment the lines that alter yDomain and yRange
to see the effect it has on the charts.
