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)
