Abstract
A font of characters including a first set defined by dots and a second set outlined by dots and used as a cursor, and a plurality of characters each forming a line segment and combinable in differing quantities and types to form a bar graph presentation, measured characteristics being displayed by digital and bar graph presentations simultaneously and the bar graphs being variable in either or both directions from a reference point such as zero.

Display apparatus for producing a variable bar graph presentation on a cathode ray tube type of display, including generating means for selectively providing a plurality of characters each composed of a plurality of dots prepositioned in rows and columns to form a line segment different in length than each of the other characters, and means for combining said characters in differing quantities and types to form bar graph presentations of substantially any desired length.
A cathode ray tube type of display connected to receive a variety of measured characteristics, said display comprising:
- (a) storage means for selectively providing, upon command, any of a font of characters including alpha-numerics and a plurality of characters each composed of a plurality of dots prepositioned in rows and columns to form a line segment different in length than each of the other characters, said plurality of characters being combinable in differing quantities and types to form bar graph presentations of substantially any desired length;
- and
- (b) apparatus connected to said storing means for commanding the selection of alpha-numerics and some of the plurality of characters to visually display the measured characteristics graphically and digitally simultaneously.
A method of producing a cathode ray tube type of display for a measured characteristic comprising the steps of:
- (a) storing in a memory a font of characters including a plurality of characters each composed of a plurality of dots prepositioned in rows and columns to form a line segment different in length than each of the other characters,
- (b) selecting differing quantities and types of the plurality of characters;
- and
- (c) combining the selected quantities and types to form a bar graph presentation representative of the measured characteristics.
