BrightStat already comes along with many useful features for data handling and manipulation, statistics and data managing, all packed in an easy to use interface. XML based data and output structures simplify the future development of external viewers.

 

BrightStat was developed by Dr. Daniel Stricker. From the beginning on BrightStat was planned to run on the net, freely accessible. The aim was to provide a statistic tool with many capabilities, yet easy to use. BrightStat is expanded continually. So don't forget to come back again to see what has been added.

Useful Features 

BrightStat comes along with many useful features, for data analysis, data manipulation and graphical output.

High quality Graphs 

Since BrightStat is a Adobe Macromedia Flash (TM) application, it's especially useful for graphical output. If you have installed a pdf printer (get free one) you can print your output directly into a pdf-format file preserving your high quality high resolution graphs. Graphs are customizable. Define Minimum, Maximum and Stepsize for each Axis, choose different line, symbol or bar styles and adjust colors, format labels and titles, define error-bars, etc.. And Save your Preferences.

Modular Design 

BrightStat comes in modules. So you only download what you really need. The main application is only about 0.6 MB in size.

XML-Based

Data and Output are XML-based. Easy to handle and understand. This enables the development of data and output viewers for other applications.
