JChart2D is a Swing widget for precise runtime visualization of numerical tuples in an x-y plot. It is easy to use and is designed for runtime display. Unlike other charting tools that cover all kinds of views (pie, bar, etc.), it just creates precise x-y plots. It is thread-safe: many different threads in an application may each add data to plot. A single chart may contain multiple different traces. It also features automatic scaling, choice of unit, viewports (zooming), output to images (PNG, JPEG, and EPS), logarithmic axis, and custom rendering of datapoints (lines, dots, discs, and filled polygons).
OIO is a Web-based metadata/data management front-end which is built using Zope and works with Postgresql. No programming is required to build and manage Web-forms or to perform data mining/analysis on the collected data. It is in production at the Harbor/UCLA Medical Center for clinical outcomes management and research data. Forms created with OIO and hosted on any OIO server can be downloaded as XML files. Once downloaded from the "Forms library" and imported into an OIO server, the necessary database tables are automatically recreated and the imported forms become immediately available to the users of that OIO server.
2D / 3D Pie Chart provides both a client and server side solution for the incorporation of pie charts into Web pages. It provides versatile components so that Web authors and Java developers can easily build and publish dynamic and interactive Pie Charts. It includes many configurable features and functions for both applet and servlet development, and the documentation and examples are designed to give both a full understanding of every feature and enable you to implement both the applet and servlet quickly and easily.
3D Vertical Bar Graph provides both client and server-side solutions for the incorporation of bar graphs into Web pages. It provides versatile components so that Web authors and Java developers can easily build and publish dynamic and interactive bar graphs. There are many configurable features and functions to both the applet and servlet and as such, the documentation and examples are designed to give both a full understanding of every feature and enable you to implement both the applet and servlet quickly and easily. The series of examples gives an overview of the variety of implementations possible.
