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.
