Example:
Fig. 7-8: Linear color curve shape = 0; colors are distributed evenly over the complete result range
In the color map based on the linear color curve, the range from -105.5 dBm to -60
dBm is covered by blue and a few shades of green only. The range from -60 dBm to
-20 dBm is covered by red, yellow and a few shades of green.
Fig. 7-9: Spectrogram with default color curve
The sample spectrogram is dominated by blue and green colors. After shifting the color
curve to the left (negative value), more colors cover the range from -105.5 dBm to -60
dBm (blue, green and yellow), which occurs more often in the example. The range
from -60 dBm to -20 dBm, on the other hand, is dominated by various shades of red
only.

Markers in the Spectrogram
Markers and delta markers are shaped like diamonds in the spectrogram. They are
only displayed in the spectrogram if the marker position is inside the visible area of the
spectrogram. If more than two markers are active, the marker values are displayed in a
separate marker table.
In the spectrum result display, the markers and their frequency and level values (1) are
displayed as usual. Additionally, the frame number is displayed to indicate the position
of the marker in time (2).
