Hello, I am a beginner with TeeChart, and I am currently facing some difficulties in using TeeChart-Net. My English is not very good, so please forgive me. Here are the details:

I want to try exporting vector graphics in my code, as follows:

//string imagePath = ConstantUtil.AppFilePath + "temp\temp_report_chart_" + DateTime.Now.Ticks + cnt.ToString() + ".wmf";
//MetafileFormat metafile = chart.Export.Image.Metafile;

//metafile.Height = 370;
//metafile.Width = 758;
//metafile.Save(imagePath);

However, I have encountered an issue. When exporting in BMP format, the line thickness is normal. But when exporting in vector graphic format (WMF), the lines become thicker, and even when I modify the line thickness property, it doesn't change.

So, how should I handle this to prevent the lines from becoming too thick in WMF format?

Thank you for your assistance.
