Histogram

Histogram displays the histogram markers, which gives you a visual aid as to
where the histogram markers are placed on the display. The histogram
markers are only displayed when you are in the histogram menu or when you
select histogram in the marker menu. You can only reposition the histogram
markers from the histogram menu.

Marker Hints

You can select a marker source that is not displayed. For example, you can
select a memory that is turned off. Because the source is not displayed, the
marker is not displayed either. However, you can still adjust the position of
that marker that is not displayed, which would affect any marker
measurements you are making. Therefore, make sure you pay attention to
what the marker sources are set to when you are making marker
measurements.
You may find yourself in a situation when the markers are turned on, but they
are positioned off the display. You may notice that it can take a long time to
bring the markers back onto the display with the knob. If you set the marker
position to the time base position value, this will snap the marker to the same
location as the time base reference. The time base position value is displayed
on the screen below the waveform viewing area and to the right of the time
base reference arrow. The time base reference location is the left, center, or
right side of the display. For example, if the time base reference is set to
center and you set the marker position to the time base position value, the
marker will snap to the center of the display. Once the marker is located on
the display, you can reposition it with the knob, arrow keys, or keypad.
