asp.net change marker size with onmouseover event?

I'm using Microsoft Ch开发者_运维技巧art Control in asp.net, for a line chart, how can I change the marker size when the mouse is over a particular point?

However, I would recommend using something like ChartFX or Dundas charts or Highcharts (pure JS charting) which have greater flexibility and better API for these type of things.
