Part of series: DD004 – Data-Driven Chart 004 Subdivided Bar Charts
This chart has two 100% subdivided bar charts that use the same category labels. To save space and also avoid redundancy, the labels are placed in the center so that they identify both sets of bars. This is a good option if space is an issue. The bars on the left of the category labels are reversed, but they are still positive numbers.
A good use of this type of chart is when you are presenting two different units for the same categories of bars. It is preferred that the values for each bar be clearly identified on the outside of the end of the bar instead of using horizontal value axis.
The segment categories are described by the use of a legend. Place the segment category labels above the first bar if space permits.
