allow custom renderings of chart objects, e.g. bars in bar graphs
So rendering of a bar would be achieved by way of a callback to the user's own code (possibly)

There is a method Series.prototype.drawPoints. You can create your own version of that to draw the shapes the way you want it.

Or a callback function in order to create some custom output based on some parameter, ex: change the alpha color for selected points.

There are lots of methods in Highcharts that can be overridden, for example Highcharts.seriesTypes.bar.prototype.drawPoints.
