Beginning with Synapse 3.0 and Cranium 4.0 (Core Version 317), the functionality of the XY Graph documents and Triangular Graph documents have been combined into a single Graph document with chapters for xy graphs and triangular graphs. Please see the documentation on Graph Documents for details on working with graphs and the documentation on converting graphs for details on how to convert previous version graphs.

The XY Graphs chapter is found in XY Graph documents. The chapter manages the xy graphs displaying data found in the document's xy data sets chapter.

• XY graphs comparing estimated values versus data values are very useful for identifying error trends and outliers. Both data and estimates can be easily transferred from knowledge bases to XY graphs.
• XY graphs are very useful for identifying relationships between variables that can form the basis of new estimation techniques.

The chapter's datapane is divided into four sections:

Section	Description
XY Datasets Section	contains a field for specifying the data sets that are displayed on the current graph.
XY Graph Section	contains one large field for viewing and editing the axes, data points curves, shapes and notes that comprise the current xy graph.
General Notes Section	used to store any general notes about the current graph. This field often contains a brief overview of the current graph's contents.
Associated Documents Section	used to store links to any documents associated with the current graph.

• Report Graph Properties: activates the Report Properties Dialog that enables you to select graph attributes to add to an open Report Document.
• Goto Data Set: activates the Goto Graph's Data Set Dialog enabling you to select a data set to navigate to.

The menubar provides numerous other commands for navigation, bookmarking, file operations, units conversion, etc. See the documentation on Common Commands for details.

Topic	Description
Graph Document	the document that manages both XY and Triangular graphs.
Creating Graphs	discusses the procedure and several detailed examples of creating graphs of physical property values.
