ABSTRACT:
A processor (18) receives signals from an electronic tablet (10) that represent the positions of a stylus (12) on the tablet surface. The processor operates a cathode-ray tube (20) to display the locations represented by the tablet signals and present scales for interpreting the display as values of a function. It also stores the quantitative data represented by the display in accordance with the scales. A user can therefore enter quantitative data in an analog manner, which is more natural in many instances.
