I  have an ordinary javascript function:
     function point_it(event) {
         pos_x = event.offsetX ? (event.offsetX) : event.pageX - document.getElementById("Chart1").offsetLeft;
         pos_y = event.offsetY ? (event.offsetY) : event.pageY - document.getElementById("Chart1").offsetTop;
       }

The purpose is to get the x-coordinate and the y-coordinate of a mouse click.

But how do I call it?

The following does not work:

$("#Chart1").click(point_it(event));

Thanks
