You can create a vari sparkline using the VARISPARKLINE formula and cell values.

The vari sparkline has the following options:

Option Description
variance A number or reference that represents the bar length, such as 2 or "A1".
reference A number or reference that represents the location of the reference line, such as 0 or "A2". This setting is optional. The default value is 0.
mini A number or reference that represents the minimum value of the sparkline, such as -5 or "A3". This setting is optional. The default value is -1.
maxi A number or reference that represents the maximum value of the sparkline, such as 5 or "A4". This setting is optional. The default value is 1.
mark A number or reference that represents the position of the mark line, such as 3 or "A5". This setting is optional.
tickunit A number or reference that represents a tick unit, such as 1 or "A6". This setting is optional. The default value is 0.
legend A boolean that represents whether to display the text. The default is optional. The default value is FALSE.
colorPositive A string that represents the color sheme for variance and is larger than reference. This setting is optional. The default value is "green".
colorNegative A string that represents the color scheme for variance and is smaller than reference. This setting is optional. The default value is "red".
vertical A boolean that represents whether to display the sparkline vertically. This setting is optional. The default value is FALSE.

The vari sparkline formula has the following format:

=VARISPARKLINE(variance, reference, mini, maxi, mark, tickunit, legend, colorPositive, colorNegative, vertical)

Using Code

The following code creates vari sparklines.

Copy Code
activeSheet.setFormula(0,1,'=VARISPARKLINE(3,0,-5,5,0.5,0.5,TRUE,"green","red",FALSE)');
activeSheet.setFormula(0,0,'=VARISPARKLINE(-3,3,-5,5,0.5,0.5,TRUE,"green","red",TRUE)');
