FREEWARE

VaryPlot is a freeware tool for creating two-dimensional graphs. Data samples can be loaded from ASCII files or given by equations for x and y. Its comfortable interface allows to work with multiple graphs at the same time. Powerful cursors and the curve statistics dialog make the data analysis easy.  
 
The program displays and accepts numbers in scientific or engineering format. It is optimized for 2-dimensional plots which are paramount for every engineer. Anti aliasing and clear type fonts are supported. Graphs can be exported in bitmap or vector format for usage in your documentation.  
 
Multiple graphs can be arbitrarily arranged in windows and tabs on the workspace. Cursors and statistical information quickly provide important information about curves. Ranges in graphs can be synchronized. Curve data can be processed using equations.  
 
Graphs can be analog (Cartesian) or digital (timing diagrams). Axis can be linear or logarithmic. VaryPlot can be customized by more than 200 options. Command and data files are legible ASCII text and can be easily created by your own programs.
