Tableau: How to Make Spark Lines

Updated: May 14

Spark lines are often used in Tableau to show a large amount of date in a small area. They are tiny line charts that are added to the right of a chart to show more detail.

Step 1:

Build a bar chart using category, subcategory and sum([Sales]). Duplicate the sheet.

Step 2:

Add month([Date]) to columns. Move sum([Sales]) to rows. This will create separate line charts.

Step 3:

Right click the axis, and select Edit. Change the range to “Independent axis ranges”

Step 4:

Hide the axis, and all other headers.

Step 5:

Use both sheets in a dashboard. Hide all titles, and fit entire view.
