Zoom diagram and zoom area (7, 8)
Zoomed waveforms are shown in separate zoom diagrams, in addition to the
waveform diagrams. On the original waveform diagram, a rectangle indicates the
zoomed section of the waveform - this is the zoom area. You can modify the
zoom area by dragging the rectangle as a whole, and by dragging its edges. To
toggle between these modes, tap the zoom area. You can also set exact posi-
tions.
The frames of the zoom area and of the associated zoom diagram have the same
color, different zooms are marked with different colors. So it is easy to assign
zoom area and zoom diagram.
As for waveform diagrams, you can change the name of the zoom diagram. A
zoom in a zoom and coupled zooms are also possible.
All zooming possibilities are described in detail in the User Manual, chapter
"Zoom".
Histogram and histogram area (9, 10)
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.
