Add Text Template in Pie Chart

To show an arbitrary text in your chart you can use texttemplate, which is a template string used for rendering the information, and will override textinfo.

var data = [{
  type: "pie",
  values: [2, 5, 3, 2.5],
  labels: ["R", "Python", "Java Script", "Matlab"],
  texttemplate: "%{label}: %{value} (%{percent})",
  textposition: "inside"
}];

Customize Text Template

The following example uses textfont to customize the added text.

var data = [{
      type: "scatterternary",
      a: [3, 2, 5],
      b: [2, 5, 2],
      c: [5, 2, 2],
      mode: "markers+text",
      text: ["A", "B", "C"],
      texttemplate: "%{text}<br>(%{a:.2f}, %{b:.2f}, %{c:.2f})",
      textposition: "bottom center",
      textfont:{'family': "Times", 'size': [18, 21, 20], 'color': ["IndianRed", "MediumPurple", "DarkOrange"]}
}];

  y: ["2018-01-01", "2018-07-01", "2019-01-01", "2020-01-01"],
  x: [100, 60, 40, 20],
  textposition: "inside",
  texttemplate: "%{label}"
},{
  type: "funnel",
  name: 'Vancouver',
  orientation: "h",
  y: ["2018-01-01", "2018-07-01", "2019-01-01", "2020-01-01"],
