3 Easy Ways to Customize Excel Sparklines

After your sparklines have been created, Excel offers several tools for you to control which value points are shown, set options on the vertical axis, and define how empty values are displayed. You can also change colors, apply styles from Office’s pre-loaded style gallery or apply a custom style that you have saved.

Change Value Points

1. Click on any cell that contains a sparkline to reveal the Sparkline Tools contextual tab. Click on the Design tab [A].

2. In the Show group [B] on the Design tab, check the points you would like to add to your line.

• High Point and Low Point: Adds color-coded markers to your sparkline at the highest and/or lowest data point.
• First Point and Last Point: Adds color-coded markers to the first and last data points.
• Negative Points: Adds color-coded markers to negative values.
• Markers: Adds a marker at every data point.

Note that the style options in the Style group [C] are updated when you make changes in the Show group.

3. Review your results [D].
