Drag Data in a Graph

How To... > Work with Graphs > Drag Data in a Graph

You can drag numeric data to change them. (If you don’t want this to happen, you can prevent it by selecting the collection and choosing Collection | Prevent Changing Values In Graphs.)

Although you can use this feature to adjust your data, its real value is in seeing the effect that changing data has on other representations. For example, if you have a scatter plot with a least-squares line, you can see the effect of an outlier dynamically by dragging a point around.

You can always restore the data you have changed through Undo, or you can choose File | Revert Collection, which restores your data to its last saved state. (Revert Collection is only available if the data have been saved and the collection is selected.)
