参考技术A canvas的话,数据变了,刷新重画。
svg太难,不会。

VBS编程:怎样用VBS给EXCEL画折线图(A列X坐标,B列Y坐标), 谢谢

现有一文件:123.xls
数据格式是
A B
1 120 350
2 110 280
3 60 556
4 300 335
5 180 227
.......
120 256 118

请教:如何将本表数据画成折线图(以A列值为X坐标,B列值为Y坐标的折线图), 我学着写了以下VBS程序,请各位补充和改正

谢谢!!!!!

EXCEL_f="C:\123.xls"
Set ExcelApp = CreateObject("Excel.Application") '创建EXCEL对象
Set ExcelBook = ExcelApp.Workbooks.Add
Set ExcelSheet1 = ExcelBook.Worksheets(1) '添加工作页1
ExcelSheet1.Activate
ExcelApp.DisplayAlerts= false
'怎样画以A列值为X坐标,B列值为Y坐标的折线图 谢谢各位!

'我本VBS菜鸟,还有什么要改的请一并指出,再次谢谢
ExcelBook.SaveAs EXCEL_f '保存工作表
ExcelApp.displayalerts=true
ExcelBook.close
ExcelApp.quit
ExcelApp=null
set ExcelApp=nothing
set ExcelBook=nothing
set ExcelSheet1=nothing

ect("Excel.Application")
objExcel.Visible = true
Set objWorkbooks = objExcel.Workbooks.Open ("D:\123.xls",3,false)
x=objExcel.Cells(1,1).value
msgbox x

cells(x,y)代表x行y列的数据。

============================教程===============================
Set oExcel= CreateObject("Excel.Application")
(一) 使用动态创建的方法
首先创建 Excel 对象,使用ComObj:
oExcel = CreateObject( "Excel.Application" )
1) 显示当前窗口:
oExcel.Visible = True
2) 更改 Excel 标题栏:
oExcel.Caption = "应用程序调用 Microsoft Excel"
3) 添加新工作簿:
oExcel.WorkBooks.Add
4) 打开已存在的工作簿:
oExcel.WorkBooks.Open( "C:\Excel\Demo.xls" )
5) 设置第2个工作表为活动工作表:
oExcel.WorkSheets(2).Activate

oExcel.WorksSheets( "Sheet2" ).Activate
6) 给单元格赋值:
oExcel.Cells(1,4).Value = "第一行第四列"
7) 设置指定列的宽度(单位:字符个数),以第一列为例:
oExcel.ActiveSheet.Columns(1).ColumnsWidth = 5
8) 设置指定行的高度(单位:磅)(1磅=0.035厘米),以第二行为例:
oExcel.ActiveSheet.Rows(2).RowHeight = 1/0.035 ' 1厘米
9) 在第8行之前插入分页符:
oExcel.WorkSheets(1).Rows(8).PageBreak = 1
10) 在第8列之前删除分页符:
oExcel.ActiveSheet.Columns(4).PageBreak = 0
11) 指定边框线宽度:
oExcel.ActiveSheet.Range( "B3:D4" ).Borders(2).Weight = 3
1-左 2-右 3-顶 4-底 5-斜( \ ) 6-斜( / )
12) 清除第一行第四列单元格公式:
oExcel.ActiveSheet.Cells(1,4).ClearContents
13) 设置第一行字体属性:
oExcel.ActiveSheet.Rows(1).Font.Name = "隶书"
oExcel.ActiveSheet.Rows(1).Font.Color = clBlue
oExcel.ActiveSheet.Rows(1).Font.Bold = True
oExcel.ActiveSheet.Rows(1).Font.UnderLine = True
14) 进行页面设置:
a.页眉:
oExcel.ActiveSheet.PageSetup.CenterHeader = "报表演示"
b.页脚:
oExcel.ActiveSheet.PageSetup.CenterFooter = "第&P页"
c.页眉到顶端边距2cm:
oExcel.ActiveSheet.PageSetup.HeaderMargin = 2/0.035
d.页脚到底端边距3cm:
oExcel.ActiveSheet.PageSetup.HeaderMargin = 3/0.035
e.顶边距2cm:
oExcel.ActiveSheet.PageSetup.TopMargin = 2/0.035
f.底边距2cm:
oExcel.ActiveSheet.PageSetup.BottomMargin = 2/0.035
g.左边距2cm:
oExcel.ActiveSheet.PageSetup.LeftMargin = 2/0.035
h.右边距2cm:
oExcel.ActiveSheet.PageSetup.RightMargin = 2/0.035
i.页面水平居中:
oExcel.ActiveSheet.PageSetup.CenterHorizontally = 2/0.035
j.页面垂直居中:
oExcel.ActiveSheet.PageSetup.CenterVertically = 2/0.035
k.打印单元格网线:
oExcel.ActiveSheet.PageSetup.PrintGridLines = True
15) 拷贝操作:
a.拷贝整个工作表:
oExcel.ActiveSheet.Used.Range.Copy
b.拷贝指定区域:
oExcel.ActiveSheet.Range( "A1:E2" ).Copy
c.从A1位置开始粘贴:
oExcel.ActiveSheet.Range.( "A1" ).PasteSpecial
d.从文件尾部开始粘贴:
oExcel.ActiveSheet.Range.PasteSpecial
16) 插入一行或一列:
a. oExcel.ActiveSheet.Rows(2).Insert
b. oExcel.ActiveSheet.Columns(1).Insert
17) 删除一行或一列:
a. oExcel.ActiveSheet.Rows(2).Delete
b. oExcel.ActiveSheet.Columns(1).Delete
18) 打印预览工作表:
oExcel.ActiveSheet.PrintPreview
19) 打印输出工作表:
oExcel.ActiveSheet.PrintOut
20) 工作表保存:
if not oExcel.ActiveWorkBook.Saved then
oExcel.ActiveSheet.PrintPreview
21) 工作表另存为:
oExcel.SaveAs( "C:\Excel\Demo1.xls" )
22) 放弃存盘:
oExcel.ActiveWorkBook.Saved = True
23) 关闭工作簿:
oExcel.WorkBooks.Close
24) 退出 Excel:
oExcel.Quit
(二) 使用VBS 控制Excle二维图
1)选择当第一个工作薄第一个工作表
set oSheet=oExcel.Workbooks(1).Worksheets(1)
2)增加一个二维图
achart=oSheet.chartobjects.add(100,100,200,200)
3)选择二维图的形态
achart.chart.charttype=4
4)给二维图赋值
set series=achart.chart.seriescollection
range="sheet1!r2c3:r3c9"
series.add range,true
5)加上二维图的标题
achart.Chart.HasTitle=True
achart.Chart.ChartTitle.Characters.Text=" Excle二维图"
6)改变二维图的标题字体大小
achart.Chart.ChartTitle.Font.size=18
7)给二维图加下标说明
achart.Chart.Axes(xlCategory, xlPrimary).HasTitle = True
achart.Chart.Axes(xlCategory, xlPrimary).AxisTitle.Characters.Text = "下标说明"
8)给二维图加左标说明
achart.Chart.Axes(xlValue, xlPrimary).HasTitle = True
achart.Chart.Axes(xlValue, xlPrimary).AxisTitle.Characters.Text = "左标说明"
9)给二维图加右标说明
achart.Chart.Axes(xlValue, xlSecondary).HasTitle = True
achart.Chart.Axes(xlValue, xlSecondary).AxisTitle.Characters.Text = "右标说明"
10)改变二维图的显示区大小
achart.Chart.PlotArea.Left = 5
achart.Chart.PlotArea.Width = 223
achart.Chart.PlotArea.Height = 108
