I have used the following code to copy a chart from an excel sheet and save it as an image.
Workbook wb1 = new Workbook();
chart = wb1.Worksheets.Charts;
chart.NSeries.HasUpDownBars = true;
bmp = chart.ToImage();
But the image seems to be dropping the the excel bars.
I have attached the excel sheet and the image file for your reference.
I need to get around this problem ASAP.
