Signal bar
The signal bar is the control center for all waveforms. All enabled waveforms are
shown on the left side of the signal bar. On the right side of the signal bar, you
see the signal activators of inactive waveforms. Tap a signal activator to enable
the waveform.
Each waveform is represented by a signal icon. If the waveform is shown in a dia-
gram, the signal icon displays its main vertical and acquisition settings. If you tap
a signal icon, the dialog with vertical settings for this waveform opens. If you tap
the "Minimize" icon on the signal icon, the waveform switches from the diagram
area to the signal icon: the icon shows the real-time signal preview. See
ter 6.4, "Working with waveforms"
on page 48 for a detailed description.
, the signal icons C1 and C2 show the main settings, and the wave-
forms are displayed in diagrams. Other waveforms are minimized and shown as
signal preview.

5 = Termination
If the signal bar contains many signal icons, and not all icons are visible, touch
one of the icons and scroll left or right until the required icon appears.
You can also switch off the signal bar: "Menu" > "Settings" > "Appearance" >
"Diagram" > "Show signal bar".
Histogram and histogram area
A histogram shows the frequency of occurrence of voltage or time values in a bar
chart directly in the diagram. The rectangular histogram area indicates the part of
the waveform that is considered in the histogram. The vertical histogram counts
the voltage values, and the horizontal histogram counts time values. You can
switch between vertical and horizontal mode, and modify the histogram area by
dragging the rectangle as a whole, by dragging its edges, or by setting exact posi-
tions.
