对象_chart的方法名称失败

Question

I am getting a Run Time error 1004 :Method name of object _chart failed while I try to name my chart. Sometimes this runs, and sometimes it doesn't. Here is the part that causes the error, (the whole macro is really long, so I haven't posted it all.)

Drawing a 3D col chart of the histogram:

Range("U1:R23").Select
    Charts.Add
    ActiveChart.ChartType = xlCylinderCol
    ActiveChart.Name = "mcChart" -----------> Error
With ActiveChart
.HasTitle = True
.ChartTitle.Characters.Text = "Dynamic Weight Chasing Histogram" & Chr(10) & "Local SWT ,File:" & Name & ", Roadforce-Check Spin" & Chr(10) & "assembly after dimensions changed, Old software"
.Axes(xlCategory, xlPrimary).HasTitle = True
.Axes(xlCategory, xlPrimary).AxisTitle.Characters.Text = "weights(Oz)"
Charts("mcChart").SeriesCollection(1).XValues = Array(0, 0.25, 0.5, 0.75, 1, 1.25, 1.5, 1.75, 2, 2.25, 2.5, 2.75, 3, 3.25, 3.5, 3.75, "4-5", "5-6", "6-7", "7-8", "8-9", "9-10")
.SeriesCollection([4]).Interior.Color = RGB(139, 0, 0) ' dark red
.SeriesCollection([3]).Interior.Color = RGB(205, 92, 92) 'indian red
.SeriesCollection([2]).Interior.Color = RGB(128, 0, 128) 'magenta
.SeriesCollection([1]).Interior.Color = RGB(144, 238, 144) 'light green
End With

Please let me know if you can find a solution to this problem.

Can you modify your code and see if it works?

dim newChart as Chart

Range("U1:R23").Select
Set newChart = Charts.Add

With newChart
   .ChartType = xlCylinderCol
   .Name = "mcChart" & Format(now, "hhmmss")

   'setting other properties
End With
