The Data Points Inspector
The Data Points inspector contains a table of all of the data in your graph. To open it, click the fourth tab in the inspector. If the inspector isn’t open, choose Data Points from the Inspectors menu.
For the most part, you can use this inspector like a miniature, minimally-featured spreadsheet; each row represents a point on the graph. Double-click a cell to add or edit a value. Press Tab to move to the next cell. To sort, click the header for the column you want to sort by. Anything you enter in the Label column is added as a text label for the corresponding point.
What’s especially useful is that you can copy and paste rows between this table and a spreadsheet, text editor, or outliner application. See the Importing section for more details about sharing data with other applications.
This inspector is also a handy way to select specific points. Any points you select in the table are also selected on the canvas.
The Connect Points button is a shortcut for quickly connecting the selected points with a line; this is especially useful if you just pasted a bunch of data.
