I need to add special symbols (e.g., ascii 135 - the double dagger) but I haven't been able to figure out how to do it. Simply setting the label results in the Excel chart displaying a little box with a question mark in it. It's obviously not recognizing my input as a displayable character. Any help would be appreciated.
chart.NSeries[seriesCtr].Points[pointsCtr].DataLabels.Text = Convert.ToChar(135).ToString();
