- 1. 将Excel中的图表导出成gif格式的图片保存到硬盘上
Sub ExportChart()理论上图表可以被保存成任何类型的图片文件,读者可以自己去尝试。
Dim myChart As Chart
Set myChart = ActiveChart

Filename:=ActiveWorkbook.Path & "Sample2.htm", _
Sheet:=ActiveSheet.name, _
Source:=" Chart 1", _
HtmlType:=xlHtmlChart

myChartObject.SeriesCollection.NewSeries
myChartObject.HasTitle = True
End Sub

End With
如果要同时设置标题字体,可以在上述代码的后面加上:

Sub charTitleText()
ActiveChart.ChartTitle.Text = "Industrial Disease in North Dakota"
End Sub - 3. 一个通过标题搜索图表的例子

End If
End If
Next
Set GetChartByCaption = myChart

Set myChart = Nothing
End Function
Sub TestGetChartByCaption()
Dim myChart As Chart
Dim ws As Worksheet
Set ws = ThisWorkbook.Worksheets("Sheet1")
Set myChart = GetChartByCaption(ws, "I am the Chart Title")
If Not myChart Is Nothing Then
Debug.Print "Found chart"
Else
Debug.Print "Sorry - chart not found"
End If
Set ws = Nothing
Set myChart = Nothing
End Sub
Chart
- 1. 通过VBA创建Chart的几种方式
使用ChartWizard方法创建
Dim ws As Worksheet
Dim rgChartData As Range
Dim myChart As Chart
Set ws = ThisWorkbook.Worksheets("Sheet1")
Set rgChartData = ws.Range("B1").CurrentRegion
Set myChart = Charts.Add
Set myChart = myChart.Location(xlLocationAsObject, ws.Name)
With myChart
.ChartWizard _
Source:=rgChartData, _
Gallery:=xlColumn, _
Format:=1, _
PlotBy:=xlColumns, _
CategoryLabels:=1, _
SeriesLabels:=1, _
HasLegend:=True, _
Title:="Version I", _
CategoryTitle:="Year", _
ValueTitle:="GDP in billions of $"
End With
Set myChart = Nothing
Set rgChartData = Nothing
Set ws = Nothing
End Sub
Dim ws As Worksheet
Dim rgChartData As Range
Dim myChart As Chart
Set ws = ThisWorkbook.Worksheets("Basic Chart")
Set rgChartData = ws.Range("B1").CurrentRegion
Set myChart = Charts.Add
Set myChart = myChart.Location(xlLocationAsObject, ws.Name)
With myChart
.SetSourceData rgChartData, xlColumns
.HasTitle = True
.ChartTitle.Caption = "Version II"
.ChartType = xlColumnClustered
With .Axes(xlCategory)
.HasTitle = True
.AxisTitle.Caption = "Year"
End With
With .Axes(xlValue)
.HasTitle = True
.AxisTitle.Caption = "GDP in billions of $"
End With
End With
Set myChart = Nothing
Set rgChartData = Nothing
Set ws = Nothing
End SubSub chart()使用ActiveSheet.ChartObjects.Add方法创建
Dim myChartSheet As Chart
Set myChartSheet = ActiveWorkbook.Sheets.Add _
(After:=ActiveWorkbook.Sheets(ActiveWorkbook.Sheets.Count), _
Type:=xlChart)
End Sub
Dim myChartObject As ChartObject
Set myChartObject = ActiveSheet.ChartObjects.Add(Left:=200, Top:=200, _
Width:=400, Height:=300)
myChartObject.Chart.SetSourceData Source:= _
ActiveWorkbook.Sheets("Chart Data").Range("A1:E5")
End Sub
如果需要指定图表的类型,可以加上这句代码:
myChartObject.ChartType = xlColumnStacked
如果需要在现有图表的基础上添加新的series,下面这行代码可以参考:
myChartObject.SeriesCollection.Add Source:=ActiveSheet.Range("C4:K4"), Rowcol:=xlRows
或者通过下面这行代码对已有的series进行扩展:
myChartObject.SeriesCollection.Extend Source:=Worksheets("Chart Data").Range("P3:P8") - 2. 一个相对完整的通过VBA创建Chart的例子
'-------------------------------------------------------------------
'Chart | VBA Constant (ChartType property of Chart object) |
'==================================================================
'Column | xlColumnClustered, xlColumnStacked, xlColumnStacked100|
'Bar | xlBarClustered, xlBarStacked, xlBarStacked100 |
'Line | xlLine, xlLineMarkersStacked, xlLineStacked |

Public Sub AddChartSheet()
Dim dataRange As Range
Set dataRange = ActiveWindow.Selection
Charts.Add 'Create a chart sheet
With ActiveChart 'Set chart properties
.ChartType = xlColumnClustered
.HasLegend = True
.Legend.Position = xlRight
.Axes(xlCategory).MinorTickMark = xlOutside
.Axes(xlValue).MinorTickMark = xlOutside
.Axes(xlValue).MaximumScale = _
Application.WorksheetFunction.RoundUp( _
Application.WorksheetFunction.Max(dataRange), -1)
.Axes(xlCategory).HasTitle = True
.Axes(xlCategory).AxisTitle.Characters.Text = "X-axis Labels"
.Axes(xlValue).HasTitle = True
.Axes(xlValue).AxisTitle.Characters.Text = "Y-axis"
.SeriesCollection(1).name = "Sample Data"
.SeriesCollection(1).Values = dataRange
End With
End Sub - 3. 通过选取的Cells Range的值设置Chart中数据标签的内容
Dim DLRange As range
Dim myChart As Chart
Dim i As Integer
Set myChart = ActiveSheet.ChartObjects(1).Chart
On Error Resume Next
Set DLRange = Application.InputBox _
(prompt:="Range for data labels?", Type:=8)
If DLRange Is Nothing Then Exit Sub
On Error GoTo 0
myChart.SeriesCollection(1).ApplyDataLabels Type:=xlDataLabelsShowValue, AutoText:=True, LegendKey:=False
Pts = myChart.SeriesCollection(1).Points.Count
For i = 1 To Pts
myChart.SeriesCollection(1). _
Points(i).DataLabel.Characters.Text = DLRange(i)
Next i
End Sub
可以手动给该图表添加Data Labels,方法是选中任意的series,右键选择Add Data Labels。如果想要为所有的series添加Data Labels,则需要依次选择不同的series,然后重复该操作。
Excel中可以通过VBA将指定Cells Range中的值设置到Chart的Data Labels中,上面的代码就是一个例子。程序执行的时候会首先弹出一个提示框,要求用户通过鼠标去选择一个单元格区域以获取到Cells集合(或者直接输入地址),如下图:
注意VBA中输入型对话框Application.InputBox的使用。在循环中将Range中的值添加到Chart的Data Labels中。 - 4. 一个使用VBA给Chart添加Data Labels的例子
Dim seSales As Series
Dim pts As Points
Dim pt As Point
Dim rngLabels As range
Dim iPointIndex As Integer
Set rngLabels = range("B4:G4")
Set seSales = ActiveSheet.ChartObjects(1).Chart.SeriesCollection(1)
seSales.HasDataLabels = True
Set pts = seSales.Points
For Each pt In pts
iPointIndex = iPointIndex + 1
pt.DataLabel.text = rngLabels.cells(iPointIndex).text
pt.DataLabel.font.bold = True
pt.DataLabel.Position = xlLabelPositionAbove
Next pt
End Sub
