yplot is an interface to the PLPlot plotting library written as an extension of yorick. This combination allows one to quickly and easily create high-quality scientific plots from data, even in large structured files. yplot implements 2D line and scatter plots, contour plots, 3D surface, mesh and scatter and line plots. The user is given full control over every aspect of the plot, including symbol types, line types, label placement, fonts, etc. The results can therefore be made suitable for high-quality scientific presentation. A 60 page Postscript tutorial is included with examples and a reference section.
