How to: Move a Chart to a Chart Sheet
The following example demonstrates how to move an existing chart from a worksheet to a separate chart sheet. To do this, call the ChartObject.MoveToNewChartSheet method for a chart you wish to move.
To transfer a chart back to the worksheet containing the source data, use the ChartObject.MoveToWorksheet method.
Dim worksheet As Worksheet = workbook.Worksheets("chartTask1")
' Create an embedded chart on the worksheet.
Dim chart As Chart = worksheet.Charts.Add(ChartType.Pie, worksheet("B2:C7"))
chart.TopLeftCell = worksheet.Cells("E2")
chart.BottomRightCell = worksheet.Cells("K15")
' Move the chart to a chart sheet.
Dim chartSheet As ChartSheet = chart.MoveToNewChartSheet("Chart")
workbook.ChartSheets.ActiveChartSheet = chartSheet
