IMapColorScale.AutoSetup

Syntax

AutoSetup(

Layer: IMapLayer;

DataAdapter: Object;

StartColor: IGxColor;

EndColor: IGxColor);

Parameters

Layer. Map layer.

DataAdapter. Cube value that corresponds to territory.

StartColor. Start gradient color.

EndColor. End gradient color.

Description

The AutoSetup method executes color scale autoset: it applies the gradient fill and calculates the (Value) for the scale tick marks preserving the specified number of intervals (Count).

Example

The example requires the Report object of the IPrxReport type. The regular report sheet must contain the map, for which a map indicator was created.

Add links to the Drawing, Map, Report, Tab system assemblies.

Sub UserProc;
Var
    Report: IPrxReport;
    Map : IMap;
    Layer : IMapLayer;
    Visual: IMapAreaVisual;
    MapScale : IMapColorScale;
    a,b : IGxColor;
Begin
    Map := (Report.Sheets.Item(0) As IPrxTable).TabSheet.Objects.Item(0).Extension As IMap;
    Layer := Map.Layers.FindByName("Regions");
    Visual := Layer.Visuals.Item(0) As IMapAreaVisual;
    a := New GxColor.CreateRGB(120, 125, 225);
    b := New GxColor.CreateRGB(170, 115, 225);
    MapScale := Report.Scales.Item(0).MapScale As IMapColorScale;
    MapScale.AutoSetup(Layer, Visual.DataAdapter, a, b);
End Sub UserProc;

After executing the example scale tick mark values are calculated and the gradient is set.
