DPlot 2.2.1.7

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, DPlots straightforward interface will appeal to anybody interested in creating presentation-quality X-Y plots and/or contour plots of 3D data.

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.

Probability scale used with the cumulative distribution of a normally distributed variable. See the Probability Scale page for more information.
Grain size distribution plot, typically used in sieve analyses. For more information see the Grain Size Distributions page.
Tripartite plot, used for shock spectra plots and vibration analyses. See the Tripartite Plot page for more information and available options.

Polar plot. See the Polar Chart page for step-by-step instructions to create a polar plot.
Triangle plot, often used in geologic studies. See the Triangle Plot page for more information.
N1.85 Hydraulic Scale, normally used to evaluate fire suppression systems and in other hydraulic studies. See the N1.85 Hydraulic Scale page for more information.

Mercator projection, the standard map projection for nautical purposes. See the Mercator Projection page for more information.
