如何使用VBA为Excel图表分配XValues [英] How to assign XValues for excel chart using VBA
问题描述
我具有用于在Excel 2013中绘制图表的VBA功能:
I have this VBA function for drawing charts in Excel 2013:
Sub DrawChart2(obj_worksheetTgt As Worksheet, ByVal XLabels As Range, ByVal DataValues As Range, ByVal chartTitle As String, a As Integer, b As Integer)
'
'obj_worksheetTgt - Object worksheet on which to be placed the chart
'XLabels - Data range for X labels
'DataValues - Data range for Y values
'chartTitle - Chart title
'a - left border position of chart in pixels
'b - top border position of chart in pixels
With obj_worksheetTgt.ChartObjects.Add(a, b, 900, 300) ' Left, Top, Width, Height
With .Chart
.ChartType = xlBarClustered
Set .SeriesCollection(1).XValues = XLabels ' Here is the error
Set .SeriesCollection(1).Values = DataValues
.Legend.Position = -4107
.HasTitle = True
.chartTitle.Text = chartTitle
.chartTitle.Font.Size = 12
With .Axes(1).TickLabels
.Font.Size = 8
.Orientation = 90
End With
End With
End With
End Sub
我这样调用函数:
ChartsWorksheet = "Summary"
Queryname = "query1"
chartTitle = "Values"
With .Worksheets("LastDayData").ListObjects(Queryname)
Set chart_labels = .ListColumns(2).DataBodyRange
Set chart_values = .ListColumns(6).DataBodyRange
End With
Call DrawChart2(.Worksheets(ChartsWorksheet), chart_labels, chart_values, chartTitle, 10, 10)
我收到一个错误:
运行时错误'1004':
Runtime Error '1004':
无效的参数
当我单击debug时,它将在上面的函数中标记"Set .SeriesCollection(1).XValues = XLabels"行.
When I click debug it marks the row "Set .SeriesCollection(1).XValues = XLabels" in the function above.
在文档中写道:
可以将XValues属性设置为工作表上的范围或 值数组,但不能是两者的组合
The XValues property can be set to a range on a worksheet or to an array of values, but it cannot be a combination of both
因此它应该能够将给定范围用作XValues的值,但我不明白为什么会出现此错误.
So it should be able to take the given range as values for XValues, but I can't understand why this error appears.
推荐答案
在您可以设置系列的值和XValue之前,需要先添加系列.使用SeriesCollection.NewSeries
方法很容易做到,如下所示:
Before you can set the Values and XValues of a series, you will need to add the series first. This is simple to do using the SeriesCollection.NewSeries
method as show below:
With ActiveSheet.ChartObjects.Add(a, b, 900, 300) ' Left, Top, Width, Height
With .Chart
.ChartType = xlBarClustered
' need to add the series before you can assign the values/xvalues
' calling the "NewSeries" method add one series each time you call it.
.SeriesCollection.NewSeries
' now that the series is added, you may assign (not set) the values/xvalues
.SeriesCollection(1).XValues = XLabels
.SeriesCollection(1).Values = DataValues
End With
End With
