Hi,

One way is to use the Add button on the Series tab of the Source data
dialog. Right click chart and pick Source Data from the context menu.

If the new series is not automatically a line series simply select it,
right click and choose Chart Type. Select required line chart.

You can also use copy and Pate special to add data to a chart.

Cheers
Andy
