PieChartRendererParams Class
Input parameters for generating a pie chart visualization based on a set of numeric fields.
public class PieChartRendererParams :
System.IEquatable<dymaptic.GeoBlazor.Pro.Model.PieChartRendererParams>
Inheritance System.Object 🡒 PieChartRendererParams
Implements System.IEquatable<PieChartRendererParams>
Constructors
PieChartRendererParams(Layer, Guid, IReadOnlyCollection, string, Nullable, Nullable, Nullable, LegendOptions, PieChartScheme, Nullable) Constructor
Input parameters for generating a pie chart visualization based on a set of numeric fields.
public PieChartRendererParams(dymaptic.GeoBlazor.Core.Components.Layers.Layer Layer, System.Guid ViewId, System.Collections.Generic.IReadOnlyCollection<dymaptic.GeoBlazor.Pro.Components.Renderers.AttributeColorInfo> Attributes, string? Shape, System.Nullable<bool> IncludeSizeVariable, System.Nullable<bool> OutlineOptimizationEnabled, System.Nullable<bool> SizeOptimizationEnabled, dymaptic.GeoBlazor.Core.Components.Layers.LegendOptions? LegendOptions, dymaptic.GeoBlazor.Pro.Model.PieChartScheme? PieChartScheme, System.Nullable<bool> ForBinning);
Parameters
Layer dymaptic.GeoBlazor.Core.Components.Layers.Layer
The layer for which the visualization is generated.
ViewId System.Guid
The view instance in which the visualization will be rendered.
Attributes System.Collections.Generic.IReadOnlyCollection<AttributeColorInfo>
A set of complementary numeric fields/expressions used to create the charts. For example, if creating an election map, you would indicate the name of each field representing the candidate or political party where their total counts are stored.
Shape System.String
Default Value: “pie”
Determines whether to create a pie chart or a donut chart.
IncludeSizeVariable System.Nullable<System.Boolean>
Indicates whether to include data-driven size in the final renderer. If true, features will be assigned a sized based on the sum of all values in the attributes param. Features with small total counts will be sized with small charts and features with large total counts will be sized with large charts. Enabling this option is good for visualizing how influential a particular feature is compared to the dataset as a whole. It removes bias introduced by features with large geographic areas, but relatively small data values.
OutlineOptimizationEnabled System.Nullable<System.Boolean>
Default Value: false
Only for polygon layers. Indicates whether the polygon’s background fill symbol outline width should vary based on view scale.
SizeOptimizationEnabled System.Nullable<System.Boolean>
Default Value: false
Indicates whether chart sizes should vary based on view scale.
LegendOptions dymaptic.GeoBlazor.Core.Components.Layers.LegendOptions
Provides options for modifying Legend properties describing the visualization.
PieChartScheme PieChartScheme
In authoring apps, the user may select a pre-defined color scheme. Pass the scheme object to this property to avoid getting one based on the background of the view.
ForBinning System.Nullable<System.Boolean>
Indicates whether the generated renderer is for a binning visualization. If true, then the input field(s) in this method should refer to aggregate fields defined in the featureReduction property of the layer.
Properties
PieChartRendererParams.Attributes Property

Property Value
System.Nullable<System.Boolean>
PieChartRendererParams.PieChartScheme Property
