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="PiechartApplet.class" archive="Piechart.jar"
width="500" height="420" mayscript>
For
an example of the graph applet executing a javascript
function please click
