Understanding Stacked Bar Charts
Stacked bar charts layer data in a way that lets you see the big picture and the detail underneath – all at once. It’s like seeing both the forest and the trees, showing you how different pieces come together to form a complete story.
These charts shine when you need to compare how segments stack up across various categories. They’re also great for digging deep into data, letting you spot both broad trends and fine details. With Tableau, working with these charts becomes a breeze, no matter your expertise level. It’s a user-friendly way to dive into complex data and come out with clear insights.
Prerequisites for Creating a Stacked Bar Chart in Tableau
Before jumping into Tableau, ensuring your data is comprehensive, up-to-date, and easily accessible is crucial.
Coefficient makes this easier than ever by importing live data from your business systems directly into Excel or Google Sheets, which can then be utilized in Tableau. This ensures that all your Tableau stacked bar charts are using the most recent data.
Step-by-Step Tutorial on Creating a Stacked Bar Chart in Tableau
Step 1. Selecting Dimensions and Measures for the Stacked Bar Chart
Navigate to your data and select ‘Region’ as a dimension.
Drag ‘Region’ into the columns shelf.
Follow that by selecting ‘Sales’ as a measure.
This time, drag ‘Sales’ onto the rows shelf, as you’ll want to visualize the sales data vertically.
Step 2. Adding Categories to Color for a Visual Differentiation
Use the search function in Tableau to find ‘Categories.’
Once found, drag ‘Category’ into the color mark to differentiate data visually based on categories.
Step 3. Making the Data Clearer with Labels and Custom Currency Formatting
To make individual data points easier to identify, drag ‘Sales’ onto the label mark.
Customize the currency format to align with your data’s scale, in this case, thousands of dollars.
Stop exporting data manually. Sync data from your business systems into Google Sheets or Excel with Coefficient and set it on a refresh schedule.
