Creating a 100% stacked bar chart

In a 100% stacked bar chart, the bars are split into colored bar segments placed on top of each other. Each bar height is 100%, and the colored bar segments represent the components' relative contributions to the total bar.


100% stacked bar chart

In the common stacked bar chart, described in Creating a stacked bar chart, the absolute values of the components make up the bars, which result in different bar heights. The 100% stacked bar chart differs from the common stacked bar chart by expressing the values of the components as percentages of the entire bar as shown above. This way the differences between the components are more put on view; not the actual values.
