If the chart is embedded on the sheet with the data, it is easy. Copy the
sheet, and the embedded copied chart points to the copied data.
If the chart is a chart sheet, then it's more complicated. Select the chart
and the worksheet with the data, right click on one of the tabs, and use
Move or Copy Sheet to MOVE them to a new workbook. Save this new workbook.
Select the two sheets in the new workbook, use Move or Copy to move them
into the original workbook. Since this is all the sheets in the new
workbook, the new workbook will close without saving changes. Reopen the new
workbook, select the chart sheet and worksheet, use Move or Copy again to
move them to the original workbook. This is your copy. Repeat the
reopen/move or copy as many times as needed.
This procedure is unchanged from Excel 2003 and earlier.
