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.
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:
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.
