The Tableau Stacked Bar Chart helps compare the data visually. This article will show you how to create it using the Sample – Superstore Data Source.
Create a Stacked Bar Chart in Tableau Approach 1
First, Drag and Drop Sales from Measures Region to Rows Shelf to create it. Since it is a Measure value, Sales will aggregate to default Sum. Once you drag them, Barplot will generate.
Next, Drag and Drop Sub-category from Dimension Region to Column Shelf. Once you drag them, a proper Tableau Barplot will generate, as we have shown below.
In this Tableau example, We want to Stack the Bar Chart by the Segments. So, we are dragging Segments from the Dimension region to the Color shelf in Marks Card.
Once you drop the Segment field onto the Colors shelf, You can see the Stacked Bar Chart.
