stdDevValue property

int stdDevValue
getter/setter pair

Specifies standard deviation number for AboveBelowAverage conditional formatting rule. Valid only if AverageType is set to AboveStdDev or BelowStdDev.

// create a Excel document.
final Workbook workbook = Workbook();

// Accessing sheet via index.
final Worksheet sheet = workbook.worksheets[0];

// Setting value in the cell.
sheet.getRangeByIndex(1, 1).setText('Mark');
sheet.getRangeByIndex(2, 1).setNumber(29);
sheet.getRangeByIndex(3, 1).setNumber(13);
sheet.getRangeByIndex(4, 1).setNumber(88);
sheet.getRangeByIndex(5, 1).setNumber(98);
sheet.getRangeByIndex(6, 1).setNumber(60);
sheet.getRangeByIndex(7, 1).setNumber(69);
sheet.getRangeByIndex(8, 1).setNumber(49);
sheet.getRangeByIndex(9, 1).setNumber(100);
sheet.getRangeByIndex(10, 1).setNumber(19);

// Applying conditional formatting.
final ConditionalFormats conditions =
    sheet.getRangeByName('A1:A10').conditionalFormats;
final ConditionalFormat condition = conditions.addCondition();

//Applying above or below average rule in the conditional formatting.
condition.formatType = ExcelCFType.aboveBelowAverage;
final AboveBelowAverage aboveBelowAverage = condition.aboveBelowAverage!;

//Set AverageType as AboveStdDev for AboveBelowAverage rule.
aboveBelowAverage.averageType = ExcelCFAverageType.aboveStdDev;

//Set value to StdDevValue property for AboveBelowAverage rule.
aboveBelowAverage.stdDevValue = 1;

//Set color for Conditional Formattting.
condition.backColor = '#FF0D0D';
condition.fontColor = '#FFFFFF';
condition.isItalic = true;
condition.isBold = true;

//save and dispose.
final List<int> bytes = workbook.saveAsStream();
File('CFAboveBelowAverage.xlsx').writeAsBytes(bytes);
