A chart recorder is disclosed which has n (n=1, 2, 3, . . . ) measuring channels, one for each of n measurement signals to be recorded, a printing device (5) which produces n isochromatic dot sequences (8) as curves each associated with one of the n measurement signals on a recording medium (4) moving past it, and 1 to n writing devices (9) for 1 to n different colors which overwrite or underwrite one or more of the dot sequences (8), at least in sections, with a continuous line (10) of another one of the n colors which follows the measurement signal of the respective channel, or a color-printing device (15) for 1 to n different colors which marks selected dots of each curve with dots (18) of another one of the n colors. Thus, the n dot sequences (8) are clearly distinguishable one from the other, particularly at curve intersections, and additional functions, such as alarm markings, can be realized.
