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. The esriClassifyDefinedInterval method is only applicable to raster class breaks renderer only.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. |
| fadeRatio | The degree with which to fade colors in a heatmap. A value of 0 indicates all color stops in the heatmap have an alpha of 1. A value of 1 indicates the color stop representing the highest density has an alpha value of 1, but all other color stops decrease in opacity significantly. Values between 0 and 1 will result in less transparent alpha values for each color stop. When the renderer is persisted, these alpha values will be persisted in the renderer's color stops. |
| 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. |
| flowTheme | Theme to be used only when working with renderers of type flow.Valid values:
|
| focus | Optional. Used for Relationship renderer. If not set, the legend will default to being square. Valid values:
|
| isAutoGenerated | Only applicable to FeatureReductionCluster renderers. Indicates whether the renderer was automatically created internally in behalf of the user by the JS API's rendering engine. When a user manually creates a FeatureReductionCluster renderer, this option should be ignored. |
| maxSliderValue | Optional. Indicates the maximum value of a slider if one was used to generate the dot value for dot density renderer. |
| minSliderValue | Optional. Indicates the minimum value of a slider if one was used to generate the dot value for dot density renderer. |
| 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:
|
| statistics | Statistics used by the legend to avoid representing data values that are beyond the dataset max and min. Only applies to renderers of type univariateColorSize with an 'above-and-below' univariateTheme. |
| type | Valid values: classedColor, classedSize, dotDensity, flow, predominance, relationship, univariateColorSize |
| univariateSymbolStyle | Symbol style or symbol pair used when creating a renderer of type univariateColorSize with an above-and-below univariateTheme. The custom style indicates the renderer uses a custom symbol pair not provided by the authoring application.Valid values: arrow, caret, circle, circle-arrow, circle-caret, circle-plus-minus, custom, happy-sad, plus-minus, square, thumb, triangle |
| univariateTheme | Theme to be used only when working with renderers of type univariateColorSize.Valid values:
|
| 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 some authoring clients 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.
