You can create a Month sparkline using the MonthSparkline function in a formula: =MONTHSPARKLINE(year, month, dataRange, emptyColor, startColor, middleColor, endColor)*. OR *=MONTHSPARKLINE(year, month, dataRange, colorRange).
The function has the following parameters:
year : The full year number, such as 2015.
month : The month number, such as 3.
dataRange : The reference represents a range where the first column is date and the second column is number, such as 'A1:B400'.
emptyColor : The color string represents days that have no value or zero value, such as 'lightgray'.
startColor : The color string represents the day where the value is the minimum value, such as 'lightgreen'.
middleColor : The color string represents the day where the value is the average of minimum and maximum, such as 'green'.
endColor : The color string represents the day where the value is the maximum value, such as 'darkgreen'.
colorRange : The reference represents a range where the data is a color string.
