Graph documents provide chapters storing XY and triangular graphs. Both types of graphs are very useful tools for visualizing the relationships between physical properties and state variables.

• 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.
• Plotting the values of vapor pressure versus temperature for a homologous series of chemicals can provide good insight into the dependence of the physical property on molecular structure.
• Plotting isoquant curves for a ternary mixture shows how different formulations can be made that have different compositions but the same physical property value.

A Graph Document contains four chapters. Each of these chapters can be accessed by clicking on its corresponding tab in the document's Tab Pane.
