I've tried extracting a chart out of an existing Excel file but it seems there is a problem with reading 3D Bars.
Workbook workbook = new Aspose.Cells.Workbook();
Chart chart = workbook.Worksheets["Tabelle2"].Charts;
Bitmap bitmap = chart.ToImage();
Attached is a screen shot of the chart in the Excel file and the image that is generate by Aspose.Cells.
Isn't it possible to extract the chart or am I doing something wrong?
