Shape properties

note

While specifying color values of the item, use the HEX format.

Common properties

Usage

const data = [
    // shape object
    {
        type: string, 
        id?: string | number,
        x?: number, // required in the default mode of Diagram
        y?: number, // required in the default mode of Diagram
        text?: string,
        editable?: boolean, // true by default
        height?: number,
        width?: number,
        fixed?: boolean, // false by default
        hidden?: boolean
    },
    // more shape objects
];

Description

Each shape object can include the following properties:

• type - (required) the type of the shape (by default: "rectangle" in the default mode, "card" in the org chart mode, "topic" in the mindmap mode)
• id - (optional) the unique id of a shape
• x - (optional) the x coordinate of the shape position. The property is required in the default mode of Diagram
• y - (optional) the y coordinate of the shape position. The property is required in the default mode of Diagram
• text - (optional) the text to be rendered in a shape
• editable - (optional) enables/disables the ability to edit the text of the shape by double-clicking on it; true by default.
  The property is not available for a custom shape.
• height - (optional) the height of a shape
• width - (optional) the width of a shape
• fixed - (optional) enables/disables movement and resizing of a shape, false by default
• hidden - (optional) defines, whether a shape will be hidden

note

The values of the height and width are calculated automatically for a "text"/"topic" shape, depending on the content of the shape.

Custom properties

Usage

const data = [
    // shape object
    {
        // ... common properties
        [key: string]?: any, // custom property
        // ... more custom properties
    },
    // more shape objects
]

Description

When preparing a data set for a custom shape, you can add any custom properties to the configuration object of a shape:

• key - (optional) a custom property for a custom shape. For details, check the Custom shape article.
  Use unique names as names for custom properties. Overriding the internal properties of the diagram shape object is forbidden as it causes the incorrect work of the diagram and its editor.

Example

const data = [
    {
        "id": "main",
        "name": "Kristin Mccoy",
        "post": "Medical director",
        "phone": "(405) 555-0128",
        "mail": "kmccoy@gmail.com",
        "photo": "../img/avatar-01.jpg"
    }
]

Properties specific for the default mode

Usage

const data = [
    // shape object
    {
        // ... common properties
        angle?: number,

        //either
        preview?: string,
        // or
        preview?: {
            img?: string,
            width?: number | string,
            height?: number | string,
            gap?: number | string,
            scale?: number
        }
    },
    // more shape objects
]

Description

When preparing a data set for shapes to load into the diagram in the default mode, you can add the following properties to the configuration object of a shape:

• angle - (optional) the angle of shape rotation
• preview - (optional) either a path to the image/a base64 image or an object with settings to configure the shape preview displayed in the shapebar of the editor. As an object, the property can contain a set of optional properties:
  • img - (optional) a path to the image or a base64 image
  • width - (optional) the width of the image
  • height - (optional) the height of the image
  • gap - (optional) sets the value of the gap attribute of the preview property for the specified type of a shape
  • scale - (optional) sets the value of the scale attribute of the preview property for the specified type of a shape
  info

  The scale property can't be applied together with the img, width, height properties

Example

const data = [
    { id: 1, x: 280, y: 0, text: "Start", type: "start", angle: 10 }
];
