Viewing Histograms

Histograms are graphical representations of data which divide it into
intervals or bins. These intervals/bins are plotted on a bar chart such that
the bar height relates to the number of data points inside each interval/bin.
You can set up histograms to visualize the results of measurement
parameters or math functions on the corresponding Measure or Math
dialogs. You can also create a histogram of a persistence display.
The range of a histogram is limited to the portion of the source trace that is
visible on screen. If you zoom in on a trace, the histogram does not contain
data for the no longer visible parts of the original trace.
Thumbnail versions of measurement parameter histograms are called
Histicons. They are available as a checkbox option on the Measure dialog.
Histicons appear on the measurement parameter table, rather than as a
new trace.

REATING A EASUREMENT
1.
Choose Measure → Measure Setup... from the menu bar to access
the Measure dialog.
2.
If the parameter of which you want a histogram exists, turn it On and
touch the Px tab to open the Parameter dialog.
If the parameter does not yet exist, first follow steps in Parameter
Setup (on page 108).
3.
Touch the Histogram button at the bottom of the Parameter dialog.
4.
Choose the math trace (F1-F12) in which to display the histogram.
5.
Touch the new Fx descriptor box to display the Function dialog, then
touch the Histogram tab at the right to display the Histogram right-
hand dialog.

Regardless of which type, the histogram is created as a
math (Fx) trace. The number of sweeps comprising the
histogram is shown on the trace descriptor box:
