Print and PrintPreview series'' line disappeared

[Lan Mo]

Hi,
V4.4.0.51 & VS2003

When I print and preview chart, the color series lines disappeared. please see attached screen image.
Any Idea?

Thanks,
Lan

My code for print and printpreview are:
public void Print()
{
PrintDialog pPrintDialog=new PrintDialog();
pPrintDialog.Document = this.chtReport.PrintDocument;

if (pPrintDialog.ShowDialog() == DialogResult.OK)
{
this.chtReport.PrintDocument.Print();
}
}

public void Preview()
{
try
{
PrintPreviewDialog pPrintPreviewDialog=new PrintPreviewDialog();
pPrintPreviewDialog.Document = this.chtReport.PrintDocument;
pPrintPreviewDialog.ShowDialog();
}
catch(Exception exp)
{
clsComm.MsgBox(exp.Message);
}

}

Hi,
Please close this issue because I figured out it.
What I did is to set the PrintColorMode to "Color" instead of default 'CheckPrint'

this.chtReport.PrintColorMode = ChartPrintColorMode.Color;

thanks,

Lan
