Appomattox is a project to build a set of cross-platform mapping objects for the .NET framework. It is also a desktop GIS application. It currently supports the following data sources: shapefiles, raster data (JPEG, GIF, TIFF, bitmap, and PNG), and PostGIS. The goal of Appomattox is to provide an elegant and intuitive user interface for mapping and Geographic Information Systems (GIS) without sacrificing power and functionality.
DiaCanvas is a generalized version of the drawing canvas used by DIA. It extends some features used by DIA and adds new ones, while preserving as many of the original features as possible. This project is no longer actively maintained. It is suggested that you try DiaCanvas2 instead.
GraphPak is a programming library of 2D and 3D charting objects for the Qt toolkit. It provides software developers with a set of C++ objects to easily create charts or graphs that aid in the visual presentation of technical and business data. This release includes Bar, Line, Pie, Ring, Area, Hi-Lo, Box and Whisker, and Polar charts. It is based on the KD Chart product from Klarälvdalens Datakonsult AB.
GtkDatabox is a widget for the GTK+ library designed to display large amounts of numerical data quickly and easily. It allows for one or more data sets of thousands of data points (X and Y coordinates) to be displayed and updated in split seconds. It offers the ability to zoom into and out of the data, and to navigate through your data by scrolling. In addition to rulers and a simple coordinate cross, it allows you to add one (or even more) configurable grids like on an oscilloscope. Data may be presented as dots, lines connecting the data, or vertical bars. The widget allows you to easily transform pixel coordinates into data coordinates, thus allowing you to easily create powerful applications for data analysis.
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).
The JOpenChart library and toolkit provides the means to create different kinds of charts, including pie charts, line charts, and plot charts. Furthermore, it contains components for embedding charts into Swing or Web applications. The library's Renderer Interface API makes it very easy to add new renderers for different chart types. Classes to interpolate measured data and to plot mathematical functions are also included.
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.
