About using graphs in Discoverer

Discoverer provides a wide range of graphs to help you analyze data visually (e.g. area, bar, line, and scatter graph). For a complete list of graph types available in Discoverer, see "About graph types available in Discoverer".

Discoverer creates a graph for each worksheet automatically, which you can display, hide, and edit.

Each Discoverer worksheet can have one graph. You create a graph for the items currently displayed on a worksheet. Before you create a graph, make sure that you display the numeric worksheet values that you want to plot on the graph.

You can drill up and down in a Discoverer graph in the same way as you can drill in a worksheet (for more information, see "How to drill up and down").

Discoverer provides the Edit Graph dialog to help you create and edit graphs (see figure below).

The Edit Graph dialog helps you:

• choose a graph type and a graph style

• choose the data that you want to represent in a graph

• specify how the graph will look

If you change the data displayed in a worksheet, the graph automatically updates to show the new data.

Once you have created a graph, you can edit the graph using the Edit Graph dialog, or edit areas of the graph using the Graph toolbar and right-click menus (for more information, see "How to edit a graph").

You can hide and display a worksheet graph (for more information, see "How to hide and display a graph").

When you save a workbook, Discoverer saves graphs automatically for you as part of the worksheets in the workbook. In other words, you do not have to explicitly save graphs.

Notes:

• To edit a Discoverer graph, you must use the same Discoverer tool that you used to create the graph. In other words:

  • if you created a graph using Discoverer Plus Relational, you must use Discoverer Plus Relational to edit the graph

  • if you created a graph using Discoverer Desktop, you must use Discoverer Desktop to edit or view the graph

• Graphs created in Discoverer Plus Relational can be viewed in Discoverer Plus Relational, Discoverer Viewer, and Discoverer portlets.

• Graphs created in Discoverer Desktop can only be viewed in Discoverer Desktop.

• A worksheet can have both a Discoverer Plus Relational graph and a Discoverer Desktop graph saved with the worksheet.

• When you print a worksheet with a graph in Discoverer Plus Relational, the worksheet and graph print on separate pages. For more information about how to print a worksheet and graph on the same page, see "About printing in Discoverer Plus Relational".
