Installation
To install the package, unzip the distribution file to your disk and it will create a directory named PieChartApplet\. Start the chart designer by double clicking the Designer.html file.

Deployment

Place the com.objectplanet.gui.PieChartApplet.jar file in the directory where the html page containing the applet is.

Create a directory called com/objectplanet/gui/ where your applet file is, and copy the PieChartApplet.class file found in the same directory in the distribution.

PieChartApplet and JavaScript
You can controll an applet in an HTML page in real time using JavaScript. Each applet has a public setParameter("name", "value") method where "name" is the name of the parameter to set, and value is the parameter value to set.

<SCRIPT> function repaint() { document.PieChart.setParameter("legendOn", document.input.legendOn.checked + ""); } </SCRIPT>

<applet code="com.objectplanet.gui.PieChartApplet" width=350 height=250 archive=com.objectplanet.gui.PieChartApplet.jar name="PieChart"> <param name="sampleValues" value="100, 200, 300, 400, 500"> </applet>

<form name="input"> legendOn: <input name="legendOn" type=checkbox onClick=repaint()> </form>

Note the name="PieChart" tag in the applet tag, and the <form name="input"> tags around the input fields.
