Declaration
Property Value
| Type | Description |
|---|---|
| NumberFormatOptions | A NumberFormatOptions object that contains formatting options for displaying numbers. |
Remarks
You can specify how to display numeric values on the axis by applying number formats. For example, a number in the axis label can appear as a percentage, decimal, currency, accounting, date or time value. To apply a number format to axis labels, assign the corresponding number format code to the NumberFormatOptions.FormatCode property. This property takes effect only when the NumberFormatOptions.IsSourceLinked property, which allows you to keep the number format linked to the worksheet cell, is set to false.
Example
The following example demonstrates how to create a clustered column chart and display numbers on the value axis as percentage values. To apply the number format, set the NumberFormatOptions.IsSourceLinked property to false and assign the corresponding format code to the NumberFormatOptions.FormatCode property.
Worksheet worksheet = workbook.Worksheets["chartTask3"];
workbook.Worksheets.ActiveWorksheet = worksheet;
// Create a chart and specify its location.
Chart chart = worksheet.Charts.Add(ChartType.ColumnClustered, worksheet["B3:C5"]);
chart.TopLeftCell = worksheet.Cells["H2"];
chart.BottomRightCell = worksheet.Cells["N14"];
// Format the axis labels.
Axis axis = chart.PrimaryAxes[1];
axis.NumberFormat.FormatCode = "0%";
axis.NumberFormat.IsSourceLinked = false;
// Hide the legend.
chart.Legend.Visible = false;
