PointSelect

This event is raised when the user selects a point belonging to a dataseries.
Given that the handler contains an argument called "args", like this:

<shield:ShieldChart runat="server">
    <ClientEvents PointSelect="pointSelect" />
...

<script type="text/javascript">
    function pointSelect(args) {
