"Temperature" Display in temperature colors. Blue corresponds to rare occurrences
of the samples, while white indicates frequent ones.
"Rainbow" Display in rainbow colors. Blue corresponds to rare occurrences of
the samples, while red indicates frequent ones.
"Fire" Display in fire colors. Yellow corresponds to rare occurrences of the
samples, while red indicates frequent ones.
"Default" Displays the waveform in its default monochrome color.

5.3.4 Threshold settings
A threshold is used for digitization of analog signals. If the signal value is higher than
the threshold, the signal state is high (1 or true for the Boolean logic). Otherwise, the
signal state is considered low (0 or false) if the signal value is below the threshold.

Threshold
A threshold is used for digitization of analog signals. If the signal value is higher than

signal state is considered low (0 or false) if the signal value is below the threshold.

Hysteresis
To avoid the change of signal states due to noise, set the hysteresis. If the signal oscil-
lates inside the hysteresis range and crosses the threshold, no state transition occurs.
