SciGraphica is a scientific application for data analysis and technical graphics. It pretends to be a clone of the popular commercial (and expensive) application “Microcal Origin”. It fully supplies plotting features for 2D, 3D and polar charts.
You can plot functions and manipulate data in worksheets, insert Python expression into them, and open several worksheets and plots and work with them interactively and at the same time. Plots are fully configurable using a control panel dialog. You can also import/export in XML format.
