Click View Datasheet.
The datasheet appears holding the data used to generate the chart.
Drag over the data in the datasheet to select it.
This is the data you want the new chart based on.

Your data is copied to the ClipBoard.
Click outside the chart to close MS Graph.

Create a new chart.
Be sure to choose the same type of chart you had before in MS Graph. An Excel worksheet opens so that you can enter data for the new chart.
