Choosing Chart Types for Your Data in Tableau
Tableau offers many different types of charts for your data. If you’ve done a bit of data analysis, you no doubt realize that different types of questions are best visualized using different types of charts. Simple bar charts may be familiar, but they don’t suit every analytical need and could lack in visual impact.
For example, imagine if you wanted to show sales results broken down by state. A typical bar chart like this one arranges the states in alphabetical order, but it’s a bit hard to visualize how the results compare geographically.
Tableau can also sort the chart so that the states appear sorted by sales, but it’s still hard to actually visualize how these results compare geographically.
To make the results easier to visualize geographically, you might want to try the Symbol map. With sales depicted as differently sized circles, it’s easy to see where most of the company’s sales are happening.
Choosing the best type of chart to visualize your analysis is often a matter of trial and error. Fortunately, the Tableau Show Me palette makes trying different options easy because all you need to do is point and click. (Not all chart options are shown on the Show Me palette; Tableau has far more options available.)
Show Me includes some popular chart types, and it lets you know which ones you can use by graying out types that don’t fit the current data in the view or selected in the Data pane.
While Show Me gives you lots of great ideas, it is also helpful to understand some basics of visual best practices. Search the web for “Tableau Visual Analysis Best Practices: A Guidebook” and you can download a white-paper with lots of great additional information to help you chose the best chart type.
