Pie Chart

<wa-pie-chart> Since 3.3 Experimental Pro Pie-chart requires access to Web Awesome Pro

Pie charts show the proportional composition of a whole as slices of a circle. They work best with a small number of categories where the relative proportions matter more than exact values.

For a variation with a hollow center, see Doughnut Chart.

<wa-pie-chart id="pie-hero" label="Browser Market Share" description="A pie chart showing browser market share with Chrome leading at 65%">
</wa-pie-chart>
<script type="module">
  const chart = document.querySelector('#pie-hero');

  chart.config = {
    data: {
      labels: ['Chrome', 'Safari', 'Firefox', 'Edge', 'Other'],
      datasets: [{
        label: 'Market Share',
        data: [65, 18, 8, 5, 4]
      }]
    }
  };
</script>

For advanced configuration such as custom plugins and direct Chart.js access, see <wa-chart>.

Examples

Providing Data with JavaScript

For dynamic data, set the config property directly. The chart will re-render automatically.

<wa-pie-chart id="pie-js-example" label="Budget Allocation" description="A pie chart of budget allocation">
</wa-pie-chart>
<script type="module">
  const chart = document.querySelector('#pie-js-example');

  chart.config = {
    data: {
      labels: ['Engineering', 'Marketing', 'Sales', 'Operations'],
      datasets: [{
        label: 'Budget',
        data: [40, 25, 20, 15]
      }]
    }
  };
</script>

Note that config is shallowly reactive. If you mutate the existing object in place, you must reassign it to trigger a re-render!

Providing Data with JSON

Place a <script type="application/json"> tag inside the component with your chart data. Each value in the data array corresponds to a label.

<wa-pie-chart label="Budget Allocation" description="A pie chart showing how a budget is allocated across departments">
  <script type="application/json">
    {
      "data": {
        "labels": ["Engineering", "Marketing", "Sales", "Operations"],
        "datasets": [{
          "label": "Budget",
          "data": [40, 25, 20, 15]
        }]
      }
    }
  </script>
</wa-pie-chart>

Custom Slice Colors

Override the default color palette using the --fill-color-* and --border-color-* CSS custom properties to apply custom colors to each slice.

<wa-pie-chart
  id="pie-colors"
  label="Custom Colors"
  description="A pie chart with custom slice colors"
  style="
    --fill-color-1: color-mix(in srgb, var(--wa-color-blue-60) 70%, transparent);
    --border-color-1: var(--wa-color-blue-60);
    --fill-color-2: color-mix(in srgb, var(--wa-color-cyan-60) 70%, transparent);
    --border-color-2: var(--wa-color-cyan-60);
    --fill-color-3: color-mix(in srgb, var(--wa-color-purple-60) 70%, transparent);
    --border-color-3: var(--wa-color-purple-60);
  "
>
</wa-pie-chart>
<script type="module">
  const chart = document.querySelector('#pie-colors');

  chart.config = {
    data: {
      labels: ['Desktop', 'Mobile', 'Tablet'],
      datasets: [{
        label: 'Traffic',
        data: [55, 35, 10]
      }]
    }
  };
</script>

Legend

Use the legend-position attribute to control where the legend appears. For pie charts, placing the legend on the side can help prevent overlap. Add without-legend to hide it entirely.

<wa-pie-chart id="pie-legend" legend-position="right" label="Legend on Right" description="A pie chart with the legend on the right side">
</wa-pie-chart>
<script type="module">
  const chart = document.querySelector('#pie-legend');

  chart.config = {
    data: {
      labels: ['Rent', 'Food', 'Transport', 'Entertainment', 'Savings'],
      datasets: [{
        label: 'Monthly Spending',
        data: [35, 25, 15, 10, 15]
      }]
    }
  };
</script>

Disabling Tooltips

Use the without-tooltip attribute to hide the tooltips that appear when hovering over slices.

<wa-pie-chart id="pie-tooltip" without-tooltip label="No Tooltips" description="A pie chart with tooltips disabled">
</wa-pie-chart>
<script type="module">
  const chart = document.querySelector('#pie-tooltip');

  chart.config = {
    data: {
      labels: ['A', 'B', 'C'],
      datasets: [{
        label: 'Values',
        data: [40, 35, 25]
      }]
    }
  };
</script>

Disabling Animations

Use the without-animation attribute to disable chart transitions.

<wa-pie-chart id="pie-anim" without-animation label="No Animation" description="A pie chart with animation disabled">
</wa-pie-chart>
<script type="module">
  const chart = document.querySelector('#pie-anim');

  chart.config = {
    data: {
      labels: ['A', 'B', 'C'],
      datasets: [{
        label: 'Values',
        data: [40, 35, 25]
      }]
    }
  };
</script>
