    Methods

    • Casts this object to the specified type. Throws error on failure.

      Type Parameters

      • T1

        The target type of the cast.

      • T2

        The type of the object to cast.

      Parameters

      Returns T1

    • Determines whether the specified object is equal to the current object.

      Parameters

      • obj: any

        The object to compare with the current object.

      Returns boolean

      true if the specified object is equal to the current object; otherwise, false.

    • Serves as the default hash function.

      Returns number

      A hash code for the current object.

    • Returns a string that represents the current object.

      Returns string

      A string that represents the current object.

    • Casts this object to the specified type. Returns null on failure.

      Type Parameters

      • T1

        The target type of the cast.

      • T2

        The type of the object to cast.

      Parameters

      Returns null | T1

    • Determines whether the specified object instances are considered equal.

      Parameters

      • objA: any

        The first object to compare.

      • objB: any

      Returns boolean

      true if the objects are considered equal; otherwise, false. If both objA and objB are null, the method returns true.

      2.0

    • Configures a newly created visual with reasonable default values given the current data set.

      Returns void

      This method is called when a visual is created by the user, but the exact configuration produced is undefined and can change between versions. This method should only be used if you want to mimic the user's action in the application, and it should only be called once. It implicity calls Spotfire.Dxp.Application.Visuals.VisualContent.ApplyUserPreferences.
      Code samples on how to create and configure a visualization are available in Spotfire Technology Network. Additional action needed for the Map Chart: in order to load the default layers (i.e. base map layer) you need to explicitly call Spotfire.Dxp.Application.Visuals.Maps.MapChart.AutoConfigureLayers.

      2.0

    • Automatically configures geocoding for this layer by (optionally) attempting to apply column classification, (optionally) changing the geocoding axis expression, and then applying automatic geocoding hierarchies.

      Parameters

      • forceAutoload: boolean | Boolean

        Force automatic loading of geocoding tables from the library.

      • allowChangeAxisExpression: boolean | Boolean

        truec> if the geocoding axis expression is allowed to be changed by automatic geocoding.

      • applyColumnClassification: boolean | Boolean

        If set to true, automatic column classification is applied.

      Returns boolean

      true if geocoding was applied to the layer, false otherwise.

      This will attempt to configure geocoding with reasonable defaults. The behavior may change in future releases.

      2.0

    • Determines whether the current plot configuration is valid.

      Returns boolean

      true if the current plot configuration is valid; otherwise, false.

      2.0

    • Refreshes data in data tables that depends on other data and is not automatically updated. This includes on-demand data with manual refresh, data functions with update behavior Manual and calculations with update behavior Invalidate. Only data tables used by this visualization will be included.

      Returns void

      This will only refresh the data tables where the Spotfire.Dxp.Data.DataTable.NeedsRefresh property is true.
