Tableau Legends per Measure (Separate Legends)
Introduced in Tableau 10.2, legend per measure allows users apply different color legends for highlight tables with multiple measures
Above is an example highlight table with multiple measures – using color to interpret these multiple measures can mislead users as higher values such as Sales can falsify the significance of measures with smaller values such as Discounts and Quantity.
In such cases, legend per measure can help you tell a better story by applying color legend at measure level rather than at global level.
To demonstrate this – let’s, first create a highlight table using dimension Category & Sub-Category with measures Profit, Sales, Quantity & Discount from the Superstores data set.
Creating a highlight table in Tableau
Drag dimension Category and Sub-Category to the rows shelf
Add measures Profit, Sales, Quantity & Discount to the label shelf
Choose text tables under Show Me tab
Change marks card from Automatic to Square
Drag Measure Values to the color shelf
To enable legend per measure, under Measure Values choose ‘Use Separate Legends’
Executing this and editing the legends for each measure we’ve;
This is not the best way to present this data, but when unavoidable – this technique can help you bypass the challenge of having measures with higher values falsifying the significance of measures with smaller values
