autoplacement

info

The autoplacement property works only in the default mode of the editor (type:"default") and only for shapes

Description​

Optional. An object with configuration settings for auto-placement of shapes

Usage​

autoplacement?: {
    mode?: "direct" | "edges",
    graphPadding?: number,
    placeMode?: "orthogonal" | "radial"
};

Parameters​

The autoplacement object has the following parameters:

  • mode - (optional) the mode of connecting shapes, "direct" (by default) or "edges"
  • graphPadding - (optional) sets the distance between unconnected diagrams, "200" by default
  • placeMode - (optional) sets the mode of placement of shapes, "orthogonal" (by default) or "radial"

Default config​

autoplacement: {
    mode: "direct",
    graphPadding: 200,
    placeMode: "orthogonal"
}

Example​

const editor = new dhx.DiagramEditor("editor_container", {
    autoplacement: {
        graphPadding: 100,
        mode: "edges",
        placeMode: "radial"
    }
});

Modes of connecting shapes​

"direct" mode​

Connector lines with no arrows are aligned "from center to center"; they are straight and diagonal.

"edges" mode​

Connector lines are aligned "from side to side".

info

To add arrows to the lines, specify forwardArrow: "filled" or backArrow: "filled" in the configuration of a line object.

The connector lines in the "edges" mode can be:

  • either straight (if you set connectType: "straight" property of a line object)

  • or 90-degree curved (if you set connectType: "elbow" property of a line object)

Modes of placement of shapes​

"orthogonal" mode​

Shapes are arranged along vertical and horizontal lines

  • "orthogonal" arrangement with lines in the "direct" mode

  • "orthogonal" arrangement with lines in the "edges" mode

"radial" mode​

Shapes are arranged on imaginary circles relative to the central shape, i.e. a shape with the most connections

  • "radial" arrangement with lines in the "direct" mode

  • "radial" arrangement with lines in the "edges" mode

Change log:

  • The placeMode parameter is added in v5.0
  • The autoplacement property is added in v3.0
