Openchart2 provides a powerful and simple interface for Java programmers to create two-dimensional charts and plots.

Openchart2 is a full-featured 2D plotting solution for Java applications.

Openchart2 features an assortment of graph styles, including advanced scatter plots, bar graphs, and pie charts.

Openchart2 supports a variety of chart types, including:
· Bar Charts - including Stacked Bar Charts
· Pie Charts
