1. please expose the 'id' attribute of series. highCharts and highStock can use chart.get(id) to get an series/axis/point. point and axis and explicitly get and set an id attribute except series.
2. add function 'getPointsByCategory'. I am using a column chart and I have to get points in specific column, but I have to do it myself because I can't find a function to do it.

best wishes for a more perfect highCharts. Thank you very much.
