谁会用vb描点画图

1,加入comm控件就可以用Input/Output属性读取数据了。

2，用VB打开Excel，如

Dim appExcel As Object

Dim wbkName As Object

Dim shtName As Object

Dim strSavePath As String

'Create the Excel file

10 Set appExcel = CreateObjec("Excel.Application")

20 Set wbkName = appExcel.workbooks.Add

30 Set shtName = wbkName.worksheets(1)

40 wbkName.worksheets(1).Name = "Sheet1"

50 appExcel.Range("A1").Value = "Channel"

60 strSavePath = App.Path & "\Test.xls"

70 wbkName.SaveAs strSavePath

80 appExcel.quit

3,可以用line语句或者用MSChar控件，MSchar.ChartData = dblData1_2'二维数组，注意坐标是（y，x）。
