How to add text inside the doughnut chart using Chart.js?

How to render Text inside the doughnut chart, I am using ChartJs.

You have to modify the code like: in chart.Doughnut.defaults

labelFontFamily : "Arial",
labelFontStyle : "normal",
labelFontSize : 24,
labelFontColor : "#666"

and then in function drawPieSegments

ctx.fillText(data[0].value + "%", width/2 - 20, width/2, 200);

See this pull:

here is a fiddle implementing the same.

How to add text inside the doughnut chart using Chart.js, In this article I will demonstrates that how can you use the pluginServices to display the text in the center of the doughnut chart. In this article I will demonstrates that how can you use the pluginServices to display the text in the center of the doughnut chart. Pie and doughnut charts are probably the most commonly used charts. Sometimes you would like to create a doughnut chart with a label in the center of it. Start with the simple html which contains the canvas element:

None of the other answers resize the text based off the amount of text and the size of the doughnut. Here is a small script you can use to dynamically place any amount of text in the middle, and it will automatically resize it.

It will take any amount of text in the doughnut sized perfect for the doughnut. To avoid touching the edges you can set a side-padding as a percentage of the diameter of the inside of the circle. If you don't set it, it will default to 20. You also the color, the font, and the text. The plugin takes care of the rest.

The plugin code will start with a base font size of 30px. From there it will check the width of the text and compare it against the radius of the circle and resize it based off the circle/text width ratio.

This is the plugin code

  beforeDraw: function (chart) {
    if ( {
      //Get ctx from string
      var ctx = chart.chart.ctx;

      //Get options from the center object in options
      var centerConfig =;
      var fontStyle = centerConfig.fontStyle || 'Arial';
      var txt = centerConfig.text;
      var color = centerConfig.color || '#000';
      var sidePadding = centerConfig.sidePadding || 20;
      var sidePaddingCalculated = (sidePadding/100) * (chart.innerRadius * 2)
      //Start with a base font of 30px
      ctx.font = "30px " + fontStyle;

      //Get the width of the string and also the width of the element minus 10 to give it 5px side padding
      var stringWidth = ctx.measureText(txt).width;
      var elementWidth = (chart.innerRadius * 2) - sidePaddingCalculated;

      // Find out how much the font can grow in width.
      var widthRatio = elementWidth / stringWidth;
      var newFontSize = Math.floor(30 * widthRatio);
      var elementHeight = (chart.innerRadius * 2);

      // Pick a new font size so it will not be larger than the height of label.
      var fontSizeToUse = Math.min(newFontSize, elementHeight);

      //Set font settings to draw it correctly.
      ctx.textAlign = 'center';
      ctx.textBaseline = 'middle';
      var centerX = ((chart.chartArea.left + chart.chartArea.right) / 2);
      var centerY = (( + chart.chartArea.bottom) / 2);
      ctx.font = fontSizeToUse+"px " + fontStyle;
      ctx.fillStyle = color;

      //Draw text in center
      ctx.fillText(txt, centerX, centerY);

And you use the following options in your chart object

options: {
  elements: {
      center: {
      text: 'Desktop',
      color: '#36A2EB', //Default black
      fontStyle: 'Helvetica', //Default Arial
      sidePadding: 15 //Default 20 (as a percentage)

Here is cleaned up and combined example of above solutions - responsive (try to resize the window), supports animation self-aligning, supports tooltips

I'm using a doughnut chart in Angular Chart. I want to place some text in the center of the doughnut. I've read this question's answers but none of them works for me, because I have tooltips and for some reason the text disappears when you hover the chart. Moreover, I need to provide this text from "outside" - custom text, e.g. a title.

I'd avoid modifying the chart.js code to accomplish this, since it's pretty easy with regular CSS and HTML. Here's my solution:


<canvas id="productChart1" width="170"></canvas>
<div class="donut-inner">
    <h5>47 / 60 st</h5>
    <span>(30 / 25 st)</span>


.donut-inner {
   margin-top: -100px;
   margin-bottom: 100px;
.donut-inner h5 {
   margin-bottom: 5px;
   margin-top: 0;
.donut-inner span {
   font-size: 12px;

The output looks like this:
