The JetChart Library is a set of java classes that display different types of charts, from applets, java applications and servlets, in the latter case with server-side gif file generation.
The following features are implemented in the JetChart Library:
Supports JDK 1.1 and higher versions.
Dragging. It's possible to drag chart over the plotting area.
Size adjustment. Complements the dragging feature, allowing chart resizing, if desired.
Vertical and horizontal orientation. A boolean property is enough to set chart orientation.
Gradient colors. A gradient effect on the chart background enhances presentation.
Popup legends(tooltips). A boolean property enables/disables presentation of popup legends when the cursor mouse moves over coordinates areas.
2D/3D presentation.
Draggable chart legend. If dragging is enabled, chart legend can be dragged to the left, right or bottom position.
Pluggable series. The mechanism in charge of painting chart series is encapsulated inside distinct classes. Series are created and configured individually and then added to the chart context. This makes easier the presentation of charts with combined series.
Distinct classes to configure the x axis, y axis, chart legend and grid.
Supports positive and negative numbers.
Line charts, bar charts, stacked bar charts, point charts, area charts, image charts and pie charts.
Pie chart rotation and slice explosion may be handled dinamically.
Our Review: Unfortunately, the documentation doesn't work in here, nor do the examples. However, there are numerous class files (and their corresponding source files) which a knowledgable developer should be able to integrate into their program.
