Graph legend

The Graph Legend lists those assays whose profiles are displayed on the Graph. Assays are displayed in the legend in order of selection and are allocated different colours so as to be more easily distinguishable on the Graph.

Each entry in the legend comprises three pieces of information: the curve type of the property profile; the crude reference; and the Y-axis property, as described below:

• Property profile curve type: Property curves displayed on the graph can either be modelled, profile-based, or correlated. Correlated properties are indicated by a ƒ in the Graph Legend.

• Crude Reference: The reference identifying the crude.

• Y-axis property: The property shown in the property control for the corresponding Y-axis. In the case where the property control shows a group of properties, each constituent property of the group has its own separate entry in the graph legend.

  Symbol	Meaning
  ƒ	Correlated Property - the property is not directly modelled but the value is calculated using a correlation with another modelled property.

  Tip: The product's property profiles can be selected by clicking the reference in the graph legend. Selecting a property profile changes the appearance of the profile graph.
  The graph legend can be resized by dragging the divider to the left hand side.
