Remarks
Use the Protection property to prevent the chart from being modified by the user. Currently, members of the ChartProtection enumeration do not influence the chart protection. Whatever value you select, the chart will be completely locked, so that an end-user cannot select or modify it through the user interface. However, you can access the protected chart in code and apply desired changes programmatically.
Example
The following example demonstrates how to create a clustered column chart and apply chart protection using the ChartOptions.Protection 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["B2:D4"]);
chart.TopLeftCell = worksheet.Cells["H2"];
chart.BottomRightCell = worksheet.Cells["N14"];
// Specify the chart style.
chart.Style = ChartStyle.ColorDark;
// Apply the chart protection.
chart.Options.Protection = ChartProtection.All;
