Abstract

An interactive graphic system is provided for automatically recording lines, symbols or marks by inputting plotting information in a step-by-step mode in an interactive system. The systems comprise a data setter for specifying, among various predetermined graphs, a graph to be plotted and for setting plotting data concerning the graph thus specified, a plotter for providing records in association with input signals, a display for requiring the plotting data inputs, and a controller for suitably controlling the various sections. The system is formed into one unit, so that the plotter can directly plot the necessary records with plotting data given by the data setter, and that the plotting operation is simplified and the system itself is small in size and low in manufacturing cost.

Dependent claims

An interactive graphic system comprising:

a plotting means having a recording head with a recording pen positioned therein which is adapted to be driven by input signals, said plotting means having a plotting surface for recording lines, symbols or marks applied therein by said recording pen,
a keyboard including a plurality of special keys for various functions with respect to drawing a bar graph, a line graph, and a pie chart and general keys for characters, digits and symbols,
a controller coupled to said keyboard for executing predetermined programs according to data from said keyboard, and
display means coupled to said controller for displaying instructions having an appropriate input of necessary data for plotting in a step-by-step manner in an interactive system, whereby lines, symbols or marks can be directly recorded on said plotting surface of said plotting means by said keyboard.
