If you have particularly long labels for your data sets then this would be the best option. Most stacked bar charts are plotted vertically, but you have the option to show the data stacked horizontally, ultimately you need to decide what you are trying to show from your data.
#WHEN WOULD YOU USE A TREEMAP CHART SOFTWARE#
The interactive nature of tableau software makes a simple treemap into a powerful tool in the hands of a user, because they can drill down very quickly to the essential points of the story told by the data. The treemaps ractangles keep the same size (without filtering) and the filtered content is shown as part of the. Treemap is an important chart to analyze the anomalies in the data set. It is best practice to only use two or three categories per group as too many will make it very hard to see patterns in the data. When filtering interactively by pressing one bar in the chart, the treemaps content adopts to this action. A good example of a stacked chart is can be seen below. The bar chart stacked is just an extension of the bar chart, and are great for showing the total size of groups especially if there is a part to whole relationship within your data.
For example you wanted to compare prison populations but wanted to divide it further into female and male categories. Treemap charts also let you visualize hierarchical data using nested rectangles. It can help you visualize how single values compose a whole. Although, treemaps can represent much-more complex data as compared to a pie-chart. These are generally a good way to represent multiple types of data within a single bar. The size of each subpart is in proportion to the data it represents.
