D 2D & D 3D
Are plotting programs written in Free Pascal that were developed to assist engineers and scientists with their data analysis and visualization problems.[1] [2] Input data should be provided as ASCII files formatted as x,y pairs or x,y,z triplets. Graphic output can be in DXF format or as raster image.
The D_2D program[edit]
Unique features of D_2D are extracting zeros and extrema from the input data file and of Pareto fronts of F1 vs. F2 point-cloud plots to display them on the graph.

The D_2D program[edit]
Unique features of D_3D are logarithmically spaced level curves, Z-axis truncated surface plots, constrained function plots, and color legend part of the z-axis.[3]
-
Surface plot with projected gradient.
