What To Know
- When you add a dimension or measure to a visualization, Tableau will often create a legend to explain the values.
- The colors used in the legend can be customized to match the colors used in the visualization.
- The font used in the legend can be changed to match the font used in the visualization.
Legends are an essential component of any data visualization, providing context and clarity to the data being presented. In Tableau, legends can be used to identify the meaning of colors, shapes, and other visual elements used in a visualization. However, sometimes legends may not be visible by default, or you may want to customize their appearance. This guide will provide a comprehensive overview of how to show legends in Tableau, including various methods and customization options.
Displaying Legends Automatically
The simplest way to show legends in Tableau is to let the software automatically generate them. When you add a dimension or measure to a visualization, Tableau will often create a legend to explain the values. This is especially common with categorical dimensions, such as product categories or regions.
Adding Legends Manually
In some cases, Tableau may not automatically create a legend for a particular element. To add a legend manually, follow these steps:
1. Click on the “Show Me” menu.
2. Select “Legend” from the list of options.
3. Drag and drop the legend onto the visualization.
Customizing Legend Appearance
Once a legend is added, you can customize its appearance to match the design of your visualization. Here are some common customization options:
1. Title: You can add a title to the legend to provide additional context.
2. Position: The legend can be positioned anywhere on the visualization. You can drag and drop it to the desired location.
3. Size: The size of the legend can be adjusted to fit the visualization.
4. Color: The colors used in the legend can be customized to match the colors used in the visualization.
5. Font: The font used in the legend can be changed to match the font used in the visualization.
Showing Legends for Multiple Dimensions
If you have multiple dimensions in a visualization, you may want to show a legend for each dimension. To do this, follow these steps:
1. Click on the “Show Me” menu.
2. Select “Legend” from the list of options.
3. Drag and drop the legend onto the visualization.
4. Repeat steps 2-3 for each dimension you want to show a legend for.
Hiding Legends
In some cases, you may want to hide a legend. To do this, simply drag and drop the legend off the visualization.
Best Practices for Legend Design
When designing legends, it is important to follow these best practices:
1. Use clear and concise labels: The labels in the legend should be easy to understand and unambiguous.
2. Use appropriate colors: The colors used in the legend should be consistent with the colors used in the visualization.
3. Keep legends consistent: If you have multiple legends in a visualization, they should be consistent in terms of appearance and placement.
4. Use legends sparingly: Only use legends when they are necessary to provide clarity to the visualization.
In a nutshell
Legends are a powerful tool for providing context and clarity to Tableau visualizations. By understanding how to show and customize legends, you can create visualizations that are both informative and visually appealing.
