DPlot graphs and manipulates 2D and 3D data from a variety of sources in many different formats. While designed for scientists, engineers, and other technical fields, DPlot's straightforward interface will appeal to anybody interested in creating presentation-quality X-Y plots and/or contour plots of 3D data. DPlot runs on Windows 95, 98, 2000, ME, NT, 2003, XP, and Vista.
 

Multiple scaling types, including linear, logarithmic, and probability scales on the X and/or Y axes. DPlot also provides several special purpose scale types, including grain size distribution plots, tripartite grids (shock spectra), polar charts, triangle plots, N1.85 hydraulic scales, and Mercator projection.
 

Bar charts with a large number of presentation options

Box-and-whisker plots and dot graphs for one or more groups of 1D data.
