I would like to see the ability to plot waterfall charts in TIBCO Spotfire. This can either be added as a new plot type or by changing the properties of the bar chart.
From Wikipedia:
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.
