求助VB利用EXCEL画趋势图
各位大侠，我想用以下代码实现画趋势图的功能，即安排两个按键，分别话A列和B列的图并显示，遇到了RANGE方法的global问题，网上方法很多，但是都不太好用，请大家指点
PS:为了显示做得图，我把EXCEL的关闭程序注释掉了，点Command1可以做出来，但是关闭图后，再点击Command2就会报错
，即使我使用注释掉的程序，但是还是会有此问题，而且进程里的EXCEL.EXE关不掉，请大家赐教，要是能有别的方式完成趋势图也可以说说，但是数据是保存在EXCEL里的不同列中。
Dim xlApp As Excel.Application
Dim xlBook As Excel.Workbook
Dim xlSheet As Excel.Worksheet
Private Sub Command1_Click()
Range("A:A").Select
xlApp.DisplayAlerts = False
Charts.Add.ChartWizard gallery:=xlLine, HasLegend:=False, Title:="折线图表", ValueTitle:="PH值", _
Format:=2
xlApp.Visible = True
' Set xlSheet = Nothing
' xlBook.Close
' Set xlBoook = Nothing
' xlApp.Quit
' Set xlApp = Nothing
End Sub
Private Sub Command2_Click()
Range("B:B").Select
xlApp.DisplayAlerts = False
Charts.Add.ChartWizard gallery:=xlLine, HasLegend:=False, Title:="折线图表", ValueTitle:="PH值", _
Format:=2
xlApp.Visible = True
' Set xlSheet = Nothing
' xlBook.Close
' Set xlBoook = Nothing
' xlApp.Quit
' Set xlApp = Nothing
End Sub
