Dim b As New XLS.Book
Dim t As Table = Tables("测试表")
Dim s As XLS.Sheet = b.Sheets(0)
Dim Chart As WinForm.Chart = Forms("横向图表示例").Controls("Chart1")
For c As Integer = 0 To t.Cols.Count - 1 '添加列标题
    s(0, c).Value = t.Cols(c).Name
Next
For r As Integer = 0 To t.Rows.Count - 1 '填入数据
    For c As Integer = 0 To t.Cols.Count - 1
        s(r + 1, c).Value = t.rows(r)(c)
    Next
Next
'插入图表
s(t.rows.Count + 2, 1).Value = New XLS.Picture(Chart.Image, 0, 0, 422, 258)
b.Save("c:\reports\test.xls")
Dim Proc As New Process
Proc.File = "c:\reports\test.xls"
Proc.Start()

为什么导出后图表这么模糊呢

那考虑保存为图片,再添加到execl里试试
