The Xamarin.iOS Diagram is a feature-rich library for visualizing, creating, and editing interactive diagrams. It helps create flowchart, organizational charts, mind maps, use case diagrams, and more using code or a visual interface.

Organizational chart

The organizational chart helps visualize the structure of an organization. Syncfusion Xamarin.iOS Diagram control provides built-in automatic layout algorithm specifically made for organizational charts to arrange parent and child nodes’ positions automatically.

Mind map

Like the organizational chart, Xamarin.iOS Diagram control provides built-in automatic layout algorithm for the mind map diagram, which links the central topic to the sub-topics placed around the central topic in the diagram surface.

A flowchart is a visual representation of a process in which each step is represented by a different shape, which contains a short description. The Xamarin.iOS Diagram control offers various feature sets to build flowcharts easily.

Built-in nodes

Use the predefined objects that are built in the diagram control.

Custom nodes in Xamarin.iOS diagram.

Custom nodes

Create and add custom nodes easily.

Template in Xamarin.iOS diagram.


In addition to the above, design a node UI template and reuse it across multiple nodes.

Fully customize the appearance of a node.


Connectors represent the relationship between two nodes. Some of the key features are as follows.

Connectors in Xamarin.iOS diagram.


Connectors are straight, orthogonal, and curved . Choose any of these based on the type of diagram or relationship between the connected notes.

Decorators in Xamarin.iOS diagram.


Use different types of predefined arrowheads to illustrate flow direction in a flowchart diagram. Also, build custom arrowheads based on the requirement.

Like nodes, connectors' look and feel can also be customized as required. The Xamarin.iOS Diagram control provides a rich set of properties to customize connector color, thickness, dash and dot appearance, rounded corners, as well as decorators.

Data binding

Populate the organizational chart or mind map diagrams based on data from data sources. In addition, data in any format can easily be converted, mapped, and consumed in the diagram by setting a few properties, without having to write any code. Diagram also supports loading data from a List or IEnumerable collection.

Ports (connection points)

Connect to specific places on a node using different types of ports or connecting points.

Labels (annotations)

More information can be shown by adding text or labels on nodes and connectors.

Label Editing in Xamarin.iOS diagram.


Add and edit text at runtime and mark it read-only if it should not be edited.

Multi Labels in Xamarin.iOS diagram.

Multiple labels

Add any number of labels and further align them individually.

Labels include sophisticated alignment options. Labels automatically align when a node or connector moves.

Interactive features

Use interactive features to improve the editing experience of a diagram at run time. Edit a diagram easily on touchscreens.

Resizing support in Xamarin.iOS diagram.

Resize and rotate

Resize a node in eight different directions and lock the node’s aspect ratios to keep its shape. Rotate selected nodes 360 degrees.

Select and drag support in Xamarin.iOS diagram.

Undo, redo, and clipboard

For editing mistakes, undo and redo commands reverse recent changes. The selected object in the diagram can also be cut, copied, and pasted.

Connector Editing Support in Xamarin.iOS diagram.

Connector editing

Edit the connectors' route easily by dragging thumbs that are visible after selection.

Z-order Support in Xamarin.iOS diagram.


When multiple objects overlap, the z-order controls which object needs to be at the top and which at the bottom.

Custom User Handle Support in Xamarin.iOS diagram.

Quick commands

Frequently used commands like delete, connect, and duplicate can be shown as buttons near a selector. This makes it easy to perform those operations quickly instead of searching for the correct buttons in a toolbox.

Drawing tool

Draw connectors and connect them with nodes interactively by just touch and move on the drawing area.

Zoom and pan tools

View a large diagram closer or wider by zooming in and out. Also, you can navigate from one region to another by panning through the diagram.

Export the diagram in PNG and JPEG image file formats.

Save as Images in Xamarin.iOS diagram.


In addition to the above, there are several other features that enhance the diagramming experience.


Gridlines help in the alignment of objects. Precisely align nodes, connectors, and annotations when dragging by snapping them to the nearest gridlines.
