NOTE
Syncfusion recommends using Blazor Diagram Component which provides better performance than this diagram control. Blazor Diagram Component will be actively developed in the future.
Mind Map layout in Blazor Diagram Component
15 Dec 20224 minutes to read
A mind map is a diagram that displays the nodes as a spider diagram organizes information around a central concept. To create mind map, the Type of layout should be set as MindMap.
The following code example illustrates how to create an organizational chart.
@using Syncfusion.Blazor.Diagrams
@using System.Collections.ObjectModel
<SfDiagram ID="diagram" Height="600px" NodeDefaults="@NodeDefaults" ConnectorDefaults="@ConnectorDefault" Layout="@LayoutValue">
<DiagramDataSource Id="Id" ParentId="ParentId" DataSource="@DataSource" DataMapSettings="@DataMap"></DiagramDataSource>
</SfDiagram>
@code {
//Initializing MindMap layout
DiagramLayout LayoutValue = new DiagramLayout()
{
//Sets layout type as MindMap...
Type = LayoutType.MindMap,
Margin = new LayoutMargin() { Top = 20, Left = 20 }
};
List<DiagramDataMapSetting> DataMap = new List<DiagramDataMapSetting>()
{
new DiagramDataMapSetting() { Property = "Shape.Content",Field = "Label" },
};
DiagramNode NodeDefaults = new DiagramNode()
{
Width = 25,
Height = 25,
BackgroundColor = "#6BA5D7",
Annotations = new ObservableCollection<DiagramNodeAnnotation>() { new DiagramNodeAnnotation() { Id = "label1", Style = new AnnotationStyle() { Color = "black" } }, },
Style = new NodeShapeStyle { Fill = "#6BA5D7", StrokeWidth = 1, StrokeColor = "white" },
Shape = new DiagramShape()
{
Type = Syncfusion.Blazor.Diagrams.Shapes.Text,
Content = "",
Margin = new BasicShapeMargin() { Left = 5, Right = 5, Bottom = 5, Top = 5 }
}
};
DiagramConnector ConnectorDefault = new DiagramConnector
{
Type = Syncfusion.Blazor.Diagrams.Segments.Bezier,
Style = new ConnectorShapeStyle() { StrokeColor = "#6BA5D7", StrokeWidth = 2 },
TargetDecorator = new ConnectorTargetDecorator()
{
Shape = DecoratorShapes.None,
}
};
public class MindMapDetails
{
public string Id { get; set; }
public string Label { get; set; }
public string ParentId { get; set; }
public string Branch { get; set; }
public string Fill { get; set; }
}
public object DataSource = new List<object>()
{
new MindMapDetails() { Id= "1",Label="Creativity", ParentId ="", Branch = "Root"},
new MindMapDetails() { Id= "2", Label="Brainstorming", ParentId ="1", Branch = "Right" },
new MindMapDetails() { Id= "3", Label="Complementing", ParentId ="1", Branch = "Left" },
new MindMapDetails() { Id= "4", Label="Sessions", ParentId ="2", Branch = "subRight" },
new MindMapDetails() { Id= "5", Label="Complementing", ParentId ="2", Branch = "subRight" },
new MindMapDetails() { Id= "6", Label= "Local", ParentId ="3", Branch = "subRight" },
new MindMapDetails() { Id= "7", Label= "Remote", ParentId ="3", Branch = "subRight" },
new MindMapDetails() { Id= "8", Label= "Individual", ParentId ="3", Branch = "subRight" },
new MindMapDetails() { Id= "9", Label= "Teams", ParentId ="3", Branch = "subRight" },
new MindMapDetails() { Id= "10", Label= "Ideas", ParentId ="5", Branch = "subRight" },
new MindMapDetails() { Id= "11", Label= "Engagement", ParentId ="5", Branch = "subRight" },
};
}
