'Generate the second chart sheet

Dim sheetIndex As Integer = excel.Worksheets.Add(SheetType.Chart)

Dim sheet2 As Worksheet = excel.Worksheets(sheetIndex)

sheet2.Name = "Chart"

Dim chartIndex As Integer = sheet2.Charts.Add(ChartType.Column, 0, 0, 0, 0)

Dim chart As Chart = sheet2.Charts(chartIndex)

chart.Title.Text = "Revenue Distribution"

chart.Title.TextFont.IsBold = True 'Set chart title font

chart.Title.TextFont.Size = 16

'Set series

Dim series As String = "Summary!B2:B" & (ds.Tables(0).Rows.Count + 1)

chart.NSeries.Add(series, True)

chart.NSeries(0).Name = "Revenue"

Dim series1 As String = "Summary!D2:D" & (ds.Tables(0).Rows.Count + 1)

chart.NSeries.Add(series1, True)

chart.NSeries(1).Name = "sales"

chart.NSeries(1).Type = ChartType.Line

chart.NSeries(0).DataLabels.IsValueShown = True

chart.NSeries(1).DataLabels.IsValueShown = True

'Set category

chart.NSeries.CategoryData = "Summary!A2:A" & (ds.Tables(0).Rows.Count + 1)

excel.ChangePalette(Color.FromArgb(255, 255, 200), 53)

chart.PlotArea.Area.ForegroundColor = Color.FromArgb(255, 255, 200)

'Set major grid line color

excel.ChangePalette(Color.FromArgb(121, 117, 200), 54)

The following is my sample code and all work fine. Which version are you using?

Dim excel As Excel = New Excel()

Dim cells As Cells = excel.Worksheets(0).Cells


cells("A1").PutValue(1)


cells("A2").PutValue(2)


cells("A3").PutValue(3)


cells("B1").PutValue(4)


cells("B2").PutValue(5)


cells("B3").PutValue(6)

cells("C1").PutValue("a")

cells("C2").PutValue("b")

cells("C3").PutValue("c")



excel.Worksheets.Add(SheetType.Chart)

Dim chartIndex As Integer = excel.Worksheets(1).Charts.Add(ChartType.Column,0,0,0,0)

Dim chart As Chart = excel.Worksheets(1).Charts(chartIndex)

chart.Title.Text = "Revenue Distribution"

chart.Title.TextFont.IsBold = True

chart.Title.TextFont.Size = 16




chart.NSeries.Add("Sheet1!A1:A3", True)
chart.NSeries(0).Name = "Revenue"

chart.NSeries.Add("Sheet1!B1:B3", True)
chart.NSeries(1).Name = "sales"


chart.NSeries(1).Type = ChartType.Line

chart.NSeries(0).DataLabels.IsValueShown = True
chart.NSeries(1).DataLabels.IsValueShown = True
