The below regional ratio of cosmetic products sales shows bar charts in 100 percent stacked formation. Different states from the United States are illustrated with different color stacks. As the below image illustrates, a stacked bar chart, also known as a stacked bar graph, is a graph that is used to break down and compare parts of a whole. Each bar in the chart represents a whole, and segments in the bar represent different parts or categories of that whole. Not only this, stacked bar charts can be visually appealing, and you may be tempted to use one to represent the same data as shown above. You can create stacked bar charts using EdrawMax Online, as it offers free stacked bar charts templates that ease down your efforts in creating the diagrams.
