In
the applet form of the graph, any data item can be linked
to a javascript function within the current page via the
url and target elements.
To instruct
the graph applet to execute a javascript function ( rather
than url ) upon a mouse click the target element of the
data item must be set to a value of "javascript".
The
function to be executed should then be entered in the url
element of the data item.
In addition
it is vital that "mayscript" is present
in the applet tag e.g,
<applet
code="VbarchartApplet.class" archive="Vbarchart.jar" width="500"
height="420" mayscript>
