如何添加上方平均值条件格式

可能的使用场景

在Microsoft Excel或Google Sheets等工具中使用上方平均值条件格式，是一种快速且直观的突出显示数据的方式，特别是突出高于平均值的范围内的值。以下是原因：

1. 快速识别趋势：帮助你瞬间找到表现出色的值，无需手动计算平均值或扫描数字。
2. 简化数据分析：无需计算或输入公式，这是应用逻辑条件格式的自动方式，节省时间。
3. 增强视觉效果：色彩编码帮助使你的电子表格更易阅读，也更具视觉吸引力，尤其在演示时。
4. 支持决策：快速识别高于平均值的数值可以推动行动，例如奖励表现优异的员工或调查为何某些产品表现优越。

如何使用Excel添加高于平均值的条件格式

以下是分步骤在Excel中添加高于平均值的条件格式的方法：

1. 选择要应用格式的单元格区域。例如：A1:A20。
2. 转到功能区的首页标签。
3. 在样式组中点击“条件格式”。
4. 浮动到“顶部/底部规则”。
5. 选择“高于平均值…”
6. 出现的对话框会自动检测“格式化高于平均值的单元格”。你可以通过点击“与…”旁边的下拉菜单来更改格式样式（例如选择填充颜色或自定义格式）。
7. 点击“确定”。你选择的区域中高于该区域平均值的所有单元格将被高亮显示。

如何使用Aspose.Cells for .NET添加高于平均值的条件格式

Aspose.Cells完全支持在运行时对XLSX格式的Microsoft Excel 2007及更高版本提供的条件格式。这个例子展示了用于不同属性集的高于平均值条件格式的操作。

private void TestAboveAverage()
{
    // Instantiate a workbook object
    Workbook book = new Workbook();
    // Create a worksheet object and get the first worksheet
    Worksheet _sheet = book.Worksheets[0];

    AddAboveAverage(_sheet);
    AddAboveAverage2(_sheet);
    AddAboveAverage3(_sheet);

    book.Save(filePath + "AboveAverage.xlsx");
}
// This method implements the AboveAverage conditional formatting type.
private void AddAboveAverage(Worksheet _sheet)
{            

    FormatConditionCollection conds = GetFormatCondition("A11:C12", Color.Tomato, _sheet);
    int idx = conds.AddCondition(FormatConditionType.AboveAverage);
    FormatCondition cond = conds[idx];
    cond.Style.BackgroundColor = Color.Pink;
    cond.Style.Pattern = BackgroundType.Solid;
}
// This method implements an AboveAverage conditional formatting type with some custom attributes.
private void AddAboveAverage2(Worksheet _sheet)
{
    FormatConditionCollection conds = GetFormatCondition("A13:C14", Color.Empty, _sheet);
    int idx = conds.AddCondition(FormatConditionType.AboveAverage);
    FormatCondition cond = conds[idx];
    cond.AboveAverage.IsAboveAverage = false;
    cond.AboveAverage.IsEqualAverage = true;
    cond.Style.BackgroundColor = Color.Pink;
    cond.Style.Pattern = BackgroundType.Solid;
}
// This method implements an AboveAverage conditional formatting type with some custom attributes.
private void AddAboveAverage3(Worksheet _sheet)
{

    FormatCondition cond = conds[idx];
    cond.AboveAverage.IsAboveAverage = false;
    cond.AboveAverage.IsEqualAverage = true;
    cond.AboveAverage.StdDev = 3;
    cond.Style.BackgroundColor = Color.Pink;
    cond.Style.Pattern = BackgroundType.Solid;
}

// This method adds formatted conditions.
private FormatConditionCollection GetFormatCondition(string cellAreaName, Color color, Worksheet _sheet)
{
    // Adds an empty conditional formattings
    int index = _sheet.ConditionalFormattings.Add();
    // Get the formatted conditions

    formatConditions.AddArea(area);
    // Call the custom FillCell method
    FillCell(cellAreaName, color, _sheet);
    // Return the formatted conditions
    return formatConditions;
}

// This method specifies the cell shading color for the conditional formattings cellarea range.
private void FillCell(string cellAreaName, Color color, Worksheet _sheet)
{
    CellArea area = GetCellAreaByName(cellAreaName);
    int k = 0;

        for (int j = area.StartRow; j <= area.EndRow; j++)
        {
            Cell c = _sheet.Cells[j, i];
            if (!color.IsEmpty)
            {
                Style s = c.GetStyle();
                s.ForegroundColor = color;
                s.Pattern = BackgroundType.Solid;
                c.SetStyle(s);
            }
            // Set some random values to the cells in the cellarea range
            int value = j + i + k;
            c.PutValue(value);
            k++;
        }
    }

}
// This method specifies the CellArea range (start row, start col, end row, end col etc.)
// For the conditional formatting
internal static CellArea GetCellAreaByName(string s)
{
    CellArea area = new CellArea();
    string[] strCellRange = s.Replace("$", "").Split(':');
    int column;
    CellsHelper.CellNameToIndex(strCellRange[0], out area.StartRow, out column);
    area.StartColumn = column;
    if (strCellRange.Length == 1)
    {
