PointDeselect

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

<shield:ShieldChart runat="server">
    <ClientEvents PointDeselect="pointDeselect" />
...
<script type="text/javascript">
    function pointDeselect(args) {
        // handle the event
    }
</script>
