Chartpak-64 is a 1985 Abacus Software charting/graphing program for the Commodore 64 that let users enter data and produce printable business-style charts.  Here is a link to the manual.

Thanks to Edward T. for sharing this software.

All this program does is let you create a bar graph between the number 1 and 15. I wasn't sure what category to put this in because it is mostly a novelty, but it since it is also 100% BASIC, it could be a good code example for anyone wanting to add something like this to their program.
