1. What is a Stacked Bar chart?

A stacked bar chart shows the composition and comparison between values across categories. It is a form of bar chart that is a series of columns stacked horizontally, next to each other. The length of each series is determined by the value of each data point.

A stacked bar chart is ideal for:

  • Data that is segmented and added to a whole

  • Dimension with long labels

  • Comparision across the different bars

  • Compare the individual category of one category across the different bars

  • Compare the size of different categories if they're very different
