Abstract

With the development of word processing technology, there is a need to provide characters to be used on daisy wheel printers for the purpose of printing bar graphs which would be part of the documentation produced. The present expedient provides four basic characters which, in combination, would be capable of producing clearly distinguishable and effective bar graphs. These four basic characters, when used on a standard printball or printwheel printer, will give letter quality charts. Each character is unique and easily distinguished from the others, prints evenly on paper and is capable of being represented and identified on a word processing display terminal which would correlate with the printer in any word processing system. The four characters are shown in Fig. 1.
