By default, the histogram reports each bucket individually.
The cumulative option adds each bucket's count or frequency to the running total, so that the
right-most bucket reports the total count or 1 (100%), depending on whether the normalized
histogram option is active. You can turn on the cumulative option on a histogram in the
Basic menu.
On the right side of Dashboard Designer, click
Settings in the VISUAL menu.
In the Settings menu, click Basic.
Under Basic, select the Cumulative
histogram option.
You can see that the difference in the vertical axes between the upper and the lower
images; in the lower image, the accumulated values approach 1 on the right side of the
graph.
