GraphIt!

GraphIt! is a program for plotting multiple datasets with a great deal of flexibility in how the data is presented. We have designed this program to be used by scientists, engineers, technicians, executives, or anyone who has data that they would like to display graphically.

Current Features: Graphs any x-y data Up to 8 different datasets can be graphed at once Total number of datapoints only limited by the available memory Easy selection of the graph range and scaling (including log and semi-log) Several different point types and sizes which can be individually selected for each dataset Data can be imported from the MemoPad or the Clipboard Full data management
GraphIt! is fully functional, non-nagging shareware. The unregistered version provides complete functionality with the exception that only 10 data points can be stored and plotted at once. Registration allows an unlimited number of datapoints to be used.
