Linear
offset
For linear scale type, the oset is the percentage of the peak
at the left edge or lower edge of the display.For example,
on a horizontal histogram, an oset of 20% places 20% of
the peak at the lower edge of the display. Therefore,20%of
the histogram will be below the display, and the other 80%
of the histogram will be above the lower edge of the display
(displayed on the screen).

Log offset
For log scale type, the oset is in decibels at the left edge
or lower edge of the display. The histogram is plotted
according to the following formula.

P
