Bar | Classic retro game for the Commodore PET Computer (1978)

AR is a simple bar graph utility. The user enters a series of numbers and the program will construct a vertical bar graph. The program will attempt to determine an appropriate scale for the y-axis of the graph. You can add meaningful labels to each bar that are readable through a sort of menu system, and customize the graph by specifying the width of each bar and the characters used to draw them.

Entering the numbers and labels is a tedious process, and there's no way to go back if you make a mistake. On its own, this program isn't terribly useful, but the graphing routines could be incorporated into a fancier BASIC program that gets its dataset from DATA statements or a tape file.
