Abstract
A graphic recording method and a graphic recording apparatus capable of dealing with the multi-channel measurement data involving quick and minute changes, without causing a trouble in accurate reading of the recorded data, in a simple and compact configuration. In the apparatus, the multi-channel measurement data are recorded by plotting a monochromatic continuous line for each channel of the multi-channel measurement data on a recording paper; and a channel discrimination mark having a distinctive color is plotted, with respect to each monochromatic continuous line, at a regular interval.
Claims18
A method of graphically recording multi-channel measurement data given in a plurality of channels, comprising the steps of:
- recording the multi-channel measurement data by plotting a monochromatic line for each channel of the multi-channel measurement data on a recording paper;
- and
- plotting at regular intervals in overlapping relation to each monochromatic line a channel discrimination mark having a respective color.
