You can create an area sparkline using the AreaSparkline formula and cell values.
The area sparkline formula has the following options:
Option | Description |
Points | A cell range. Invalid numbers are ignored. |
Min | A number that represents the minimum value of the sparkline. This setting is optional. |
Max | A number that represents the maximum value of the sparkline. This setting is optional. |
Line1 | A number that represents a horizontal line's vertical position. This setting is optional. |
Line2 | A number that represents a second horizontal line's vertical position. This setting is optional. |
ColorPositive | A string that represents the area color of positive values. This setting is optional. |
ColorNegative | A string that represents the area color of negative values. This setting is optional. |
The area formula has the following format:
=AREASPARKLINE(points, min, max, line1, line2, colorPositive, colorNegative)
This example creates an area sparkline.
