Introduction
This tutorial teaches how to configure the parameters of JetChart applets, through
a series of examples.
The topics outlined on the left frame cover basic functionalities of JetChart applets. Each topic
description is followed by an example, presented as a real applet.
The JetChart class library is packed into three independent jar files, as explained below:
- GraphChart.jar - Contains the classes to be used to plot charts other than scatter charts and
pie charts.
- ScatterChart.jar - Contains the classes to be used to plot scatter charts, as xy charts,
xy line charts, xy image charts and bubble charts.
- PieChart.jar - Contains the classes to be used to plot pie charts.
The jar files have to be made available to browsers using the 'archive' attribute of the <applet>
tag.
The applets are wrappers around JetChart api, which is accessed through parameters. The following applets
are available:
- GraphApplet.class - To be used in conjunction with GraphChart.jar.
- ScatterApplet.class - To be used in conjunction with ScatterChart.jar.
- PieApplet.class - To be used in conjunction with PieChart.jar.
Make the applets available to browsers using the 'code' attribute of the <applet> tag.
For example, if the files above are placed at a subdirectory named 'classes', created under
the html files directory, the 'applet' tag must be the following:
<applet code="GraphApplet.class" codebase="classes" archive="GraphChart.jar" width="400" height="300">
or
<applet code="ScatterApplet.class" codebase="classes" archive="ScatterChart.jar" width="400" height="300">
or
<applet code="PieApplet.class" codebase="classes" archive="PieChart.jar" width="400" height="300">
The files above described can be found at the JetChart/demo/applets/classes directory
after decompression of the JetChart.zip file.
