Oracle introduced one new graph called “Waterfall” chart in OBIEE 11.1.1.6.0.
A waterfall chart is a special type of floating-column chart. A typical waterfall chart shows how an initial value is increased and decreased by a series of intermediate values, leading to a final value. An invisible column keeps the increases and decreases linked to the heights of the previous columns.
By default this is not visible in our graph list and need to enable manually. To do that, add this tag in your instanceconfig.xml file between <Views> element.
<Charts>
<EnableWaterfall>true</EnableWaterfall>
</Charts>
</Views>
Save the file and restart the OPMN services.
