Lines and Connectors

Add lines and connector shapes between elements

Use the line property for straight lines and the connector property for lines with arrowheads.

Line Shape

Lines use start/end point coordinates:

{
  "slides": [
    {
      "children": [
        {
          "line": {
            "x1": 50,
            "y1": 120,
            "x2": 800,
            "y2": 120,
            "outline": { "color": "4472C4", "width": 2 }
          }
        }
      ]
    }
  ]
}

Vertical Line

{
  "slides": [
    {
      "children": [
        {
          "line": {
            "x1": 200,
            "y1": 150,
            "x2": 200,
            "y2": 450,
            "outline": { "color": "ED7D31", "width": 2 }
          }
        }
      ]
    }
  ]
}

Diagonal Line

{
  "slides": [
    {
      "children": [
        {
          "line": {
            "x1": 250,
            "y1": 150,
            "x2": 750,
            "y2": 450,
            "outline": { "color": "70AD47", "width": 3 }
          }
        }
      ]
    }
  ]
}

Connector with Arrowheads

Connectors support arrowhead endpoints:

{
  "slides": [
    {
      "children": [
        {
          "connector": {
            "x1": 50,
            "y1": 130,
            "x2": 400,
            "y2": 130,
            "outline": { "color": "4472C4", "width": 2, "tailEnd": { "type": "triangle" } }
          }
        },
        {
          "connector": {
            "x1": 50,
            "y1": 200,
            "x2": 400,
            "y2": 200,
            "outline": {
              "color": "ED7D31",
              "width": 2,
              "headEnd": { "type": "triangle" },
              "tailEnd": { "type": "triangle" }
            }
          }
        }
      ]
    }
  ]
}

Arrowhead Types

Arrowheads are set via the type field of outline.headEnd (start) / outline.tailEnd (end):

ValueDescription
"triangle"Filled triangle
"stealth"Stealth arrow
"diamond"Diamond shape
"oval"Oval circle
"arrow"Open arrow
"none"No arrowhead

Arrowheads also support size control:

{
  "slides": [
    {
      "children": [
        {
          "connector": {
            "x1": 500,
            "y1": 410,
            "x2": 800,
            "y2": 410,
            "outline": {
              "color": "ED7D31",
              "width": 2,
              "tailEnd": { "type": "triangle", "width": "large", "length": "large" }
            }
          }
        }
      ]
    }
  ]
}
