Welcome to cmlplot

cmlplot is a small, simple and straightforward plotting program for GNU/Linux and MacOSX. cmlplot may be useful to people that love working from within the unix shell, hate herding the mouse around, and need a plotting program that can read standard input and can be used in unix pipelines :

tac mydata.dat | awk '{print $17,$21,$23}' | cmlplot

cmlplot can do simple x-y plots, can overlay two x-y plots, can draw histograms, can do scatter plots, and can draw contour plots of your matrices (using bicubic interpolation). It can even do pseudo-color representations of your matrices with (or without) overlaid contours.
