Click the New button on the Sheet toolbar and choose what kind of sheet you want to create. The first choice is used the most. It adds a new empty data table and linked graph to your project. You can also add a New Data Table (No Automatic Graph), a new Info sheet, a new graph of an existing data table, or a new layout. To be complete, this menu also lets you add a new analysis, but you'll find it easier to start at a data table or graph and click the Analyze button.

You can also add a new table, analysis, graph or layout by a link in the navigator.

You can also add to your project by duplicating a family of sheets or by cloning a graph.

Create a new graph of existing data

Right beside the "New" button in the toolbar is the "New Graph" button. You can click this to quickly bring up the Create New Graph dialog. Using this dialog, you can choose the input table, the type of graph, and basic options. Then click OK to create the graph.
