Remarks
The Spreadsheet allows you to use Microsoft Excel number formats to display numeric values on a chart as currency, percentages, decimals, and so on.
Use the FormatCode option to specify a number format in the invariant culture. Disable the NumberFormatOptions.IsSourceLinked property to indicate that the applied format differs from the number format of the source cells.
You can also use the FormatCodeLocal property to obtain or specify a number format based on the current (local) culture defined by the DocumentOptions.Culture property.
Example
The following example demonstrates how to create a clustered column chart and display numbers on the value axis as percentage values. To apply a number format, set the NumberFormatOptions.IsSourceLinked property to false and assign the required 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"];
// Apply a number format to axis labels.
Axis axis = chart.PrimaryAxes[1];
axis.NumberFormat.FormatCode = "0%";
axis.NumberFormat.IsSourceLinked = false;
// Hide the legend.
chart.Legend.Visible = false;
