This chart recorder with n or m (n, m=1, 2, 3, . . . ) measuring channels, one for each of n or m measurement signals to be recorded, has a printing device (5) or m continuous-line recording devices (31, 32) which produces/produce n equal colored dot sequences (8), each associated with one of the n measurement signals, or continuous lines (8', 8'') each associated with one of the m measurement signals, as measurement curves on a recording medium (4, 4') moving past it/them. Those portions (81; 81', 81'') of the dot sequences or continuous lines which are currently being formed lie behind a covering portion (51, 51') formed by the printing device (5) or the continuous-line recording devices (31, 32) and/or by other components of the chart recorder, and are invisible. The chart recorder further includes an electronic display (21, 21') with p lines each consisting of q dots on which the dot-sequence or continuous-line portions (81; 81', 81'') currently being formed are displayed as corresponding electronic dot sequences (80, 80', 80'') .
