You can create an Area sparkline using the AreaSparkline function in a formula: =AREASPARKLINE(points, min?, max?, line1?, line2?, colorPositive?, colorNegative?).
The function has the following parameters:
points: It is a range, such as "D1:D6". If a cell value is not a valid number, it will be treated as 0.
min: (optional) A number that represents the minimum value of the sparkline. The default value is the minimum value in the range.
max: (optional) A number that represents the maximum value of the sparkline. The default value is the maximum value in the range.
line1: (optional) A number that represents a horizontal line's vertical position; the line does not exist by default.
line2: (optional) A number that represents another horizontal line's vertical position; the line does not exist by default.
colorPositive: (optional) A string that represents the color of the area in which the value is positive; default value is "#787878".
colorNegative: (optional) A string that represents the color of the area in which the value is negative; default value is "#CB0000".
