XY Graphs Chapter
Applicability: Cranium, Synapse (core version 0317+)
(Click here for previous documentation)

The XY Graphs chapter is found in Graph Documents. The chapter enables you to view, create, and edit xy graphs.

Typical Usage
  • 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.
Chapter Sections

The chapter's datapane is divided into six sections:

Section Description
Descriptive Information Section contains fields for describing the graph's variables, keywords, units and a general reference for the source of the graph's data values.
XY Data Values Section contains one large field for viewing and editing the xy data values that are displayed on XY graphs.
XY Segments Section contains two fields for specifying the curve segments and region segments that appear in the current graph.
XY Graph Section contains one large field for viewing and editing the axes, segments, 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.
Chapter Commands

The XY Graphs chapter's commands are available from the chapter's Commands menu.

  • Report Graph Properties: activates the Report Properties Dialog that enables you to select graph attributes to add to an open Report Document.
  • Extract Image Points: activates the Extract XY Graph Dialog that enables you to extract numerical points from images of xy graphs.
  • Compile Keywords: compiles the keywords from each graph into the Compiled Entities Dialog which enables you to review, select, and bookmark graphs having the same keywords.
  • Go To Reference: changes to the page in the current document's Reference Chapter showing information about this graphs's reference. A graph's reference is entered into the Descriptive Information Section's Reference field.
  • Show Reference: retrieves the reference stored in the current graph's Reference Field and opens the reference's associated document.
Common Commands

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