Workbook workbook = new Workbook(FileName);

//Get the chart in the first worksheet.

Aspose.Cells.Charts.Chart chart = workbook.Worksheets[0].Charts[0];

//Add a WordArt watermark (shape) to the chart's plot area.

Aspose.Cells.Drawing.Shape wordart = chart.Shapes.AddTextEffectInChart(MsoPresetTextEffect.TextEffect2,

"CONFIDENTIAL", "Arial Black", 66, false, false, 1200, 500, 2000, 3000);

//Get the shape's fill format.

Aspose.Cells.Drawing.MsoFillFormat wordArtFormat = wordart.FillFormat;

//Set the transparency.

wordArtFormat.Transparency = 0.9;

//Get the line format and make it invisible.

Aspose.Cells.Drawing.MsoLineFormat lineFormat = wordart.LineFormat;

lineFormat.IsVisible = false;

//Save the excel file.

workbook.Save(FileName);
