[M Higgins]

Can you add a new set of data to an existing chart?

 

[Bernard Liengme]

Copy the new data
Click on Chart
Use menu item Edit | Paste Special and in the dialog stipulate New Series
Indicate if data is in rows or columns (Excel generally gets this right)
Click OK

Note you can select just the y-values, or both x- and y-values. In the
latter case, you need to specify in the Paste Special dialog that the first
column (row) holds x-values
