The authoringInfo is an object containing metadata about the authoring process for creating a renderer object. This allows the authoring clients to save specific overridable settings so that next time it is accessed via an authoring client, their selections are remembered. Non-authoring clients can ignore it. Properties for color/size/transparency sliders, theme selection, classification information, and additional properties are saved within this object.

Properties
| Property | Details |
|---|---|
| classificationMethod | Used for classed color or size. The default value is esriClassifyManual.Valid values: esriClassifyDefinedInterval, esriClassifyEqualInterval, esriClassifyManual, esriClassifyNaturalBreaks, esriClassifyQuantile, esriClassifyStandardDeviation |
| colorRamp | A colorRamp object is used to specify a range of colors that are applied to a group of symbols. |
| field1 | Contains information about an attribute field relating to Relationship renderers. |
| field2 | Contains information about an attribute field relating to Relationship renderers. |
| fields[] | An array of string values representing field names used for creating predominance renderers. |
| focus | Optional. Used for Relationship renderer. If not set, the legend will default to being square. Valid values:
|
| lengthUnit | Unit used in user interfaces to display world/map sizes and distances Valid values: centimeters, decimeters, feet, inches, kilometers, meters, miles, millimeters, nautical-miles, yards |
| numClasses | Number of classes to be associated with the relationship. Used for Relationship renderer. |
| standardDeviationInterval | Use this property if the classificationMethod is esriClassifyStandardDeviation.Valid values:
|
| type | Valid values: classedColor, classedSize, dotDensity, flow, predominance, relationship, univariateColorSize |
| visualVariables[] | An array of visualVariable objects containing additional information needed when authoring the renderer. |
Additional information
The authoringInfo object is not required with a renderer. It is only used if rendering was generated using the Scene Viewer rendering tools. All snippets provided below show a portion of what is contained within authoringInfo. Please refer to the sample snippets in the authoringInfo visual variable object for additional help.
