add a method getExtremes() to the Series object
This would allow retrieveal of max and min data for that series. On a multi-series graph the axis extremes are nice, but being able to grab the extemes of each series would allow for more flexabiilty in data display.
I set up a plugin that you can use: http://jsfiddle.net/highcharts/acPw9/

Fantastic! That does exactly what I was thinking. Thanks!

The thought here is to be able to retrive the max and min data on a given series and when they happened (x axis) in order to be able to display that data to the side fo the chart.
