DataFit is a tool used to perform nonlinear regression (curve fitting), statistical analysis & data plotting. Fit equations with up to 100 parameters to data with up to 20 independent variables. Define your own equations or choose from over 600 pre-defined equations. Results include customizable 2D/3D plots, as well as detailed fit information. Export code in BASIC or C to use an equation in a user written program. Easy to learn and use.

With XYit you can digitize xy co-ordinates of points & lines in images, enabling you to capture their original x-y values. And you can do the reverse - plotting xy numerical data back onto an image - ideal for making maps of proposed routes etc. As well as manual digitizing facilities, XYit provides automatic facilities which can follow and convert lines within an image. XYit is unique, with broad application in graphing, charting and mapping.

Imports gridded data into MS-MapPoint, to produce attractive data maps. Can handle imperfect data, holes, re-gridding, etc. Can be used to import such attributes as pollution data, seismic hazard, geological information, customer/population distribution, etc. Various text formats supported using space, tab, or comma separators. Data coordinates can be longitude,latitude coords; custom linear coords; or Ordnance Survey Grid References.
