Tableau: How to Make Spark Lines

Updated: May 13, 2021

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 2:

Step 3:

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