Overlapping Columns Part of FusionCharts XT
Overlapping columns can be used to visualize two data sets on a single chart. Similar to a simple column chart, this chart uses vertically aligned rectangular columns on one axis as data plots plotted against the discrete values shown on the other. On one axis, columns compare categories, while on the other they represent a discrete value. The width of the columns for the data series differs which makes the chart easy to compare. Both data sets need to be of the same data type like revenue or cost. Selecting or deselecting legend labels allows a single dataset view or comparison of two data sets simultaneously.
