Grafit is a data-manipulation tool and plotting program for use at all levels of the chemistry curriculum. The program is especially useful for analyzing laboratory results, such as for calorimetry, titration, Beer's law, and Job's Method experiments.
Data are typed into a scrolling window with spreadsheet-like columns that can be transformed by mathematical manipulations or combinations with other columns. For example, % transmittance data could be entered into column B and transformed to absorbance data by typing LOG(B/100). Data can be saved or opened as text files, and the graphs and data can be copied to the clipboard or drawn to a printer.
Different graphing options are available such as bar graphs or histograms of a single column of data, x-y plots for two columns of data, and three-dimensional x-y-z plots of three columns of data. Least-squares fits with standard deviation, log or polar plots, automatic or user defined scaling, grid, and point styles are some the the available options for x-y plots.
Hardware and Software Requirements
Grafit requires a Macintosh Plus, SE, Classic, SE/30, or any Macintosh II model. The programs have been tested using Macintosh system software versions 6.0x. Color is not supported. For classroom presentations a large monitor or overhead projection panel is recommended (1).
