Using a Reference Line or Band
With a reference line or band, you can focus on a certain value or range of values in your Chart. A reference line focuses on a specific value, and a reference band focuses on a certain range of values. You can add a reference line or band to the following Chart types:
- Area
- Bar
- Bubble
- Column
- Line
- Scatter
