A sparkline is a tiny chart in the background of a cell. When you use a sparkline, you can easily see the relationships between it and its underlying data. And, you can copy sparklines to adjacent cells by using the Fill Handle. Sparklines are printed as-is when you print a worksheet that contains them, unlike charts that may require special print handling.
Pro Tip: Use the Quick Analysis tool to quickly add a sparkline to your data.
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
· 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 [B] are updated when you make changes in the Show group.
