Polar Area Chart

<wa-polar-area-chart> Stable Since 3.3 Pro Included with Web Awesome Pro

Polar area charts compare values using segments that radiate from a center point with varying radius. Unlike pie charts, each segment has an equal angle while the radius varies, making them useful for comparing magnitudes without visual bias.

Providing Data with JavaScript

Link to This Section

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

<wa-polar-area-chart id="polar-js-example" label="Energy Production" description="A polar area chart of energy output">
</wa-polar-area-chart>
<script type="module">
  const chart = document.querySelector('#polar-js-example');

  chart.config = {
    data: {
      labels: ['Solar', 'Wind', 'Hydro', 'Nuclear', 'Natural Gas'],
      datasets: [{
        label: 'Output (GW)',
        data: [85, 72, 110, 95, 130]
      }]
    }
  };
</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

Link to This Section

Place a <script type="application/json"> tag inside the component with your chart data. Each value in the data array corresponds to a label, and the segment radius reflects its magnitude.

<wa-polar-area-chart label="Energy Production" description="A polar area chart showing energy production by source in gigawatts">
  <script type="application/json">
    {
      "data": {
        "labels": ["Solar", "Wind", "Hydro", "Nuclear", "Natural Gas"],
        "datasets": [{
          "label": "Output (GW)",
          "data": [85, 72, 110, 95, 130]
        }]
      }
    }
  </script>
</wa-polar-area-chart>

Custom Colors

Link to This Section

Override the default color palette using the --fill-color-* and --border-color-* CSS custom properties.

<wa-polar-area-chart
  id="polar-colors"
  label="Custom Colors"
  description="A polar area chart with custom segment colors"
  style="
    --fill-color-1: color-mix(in srgb, var(--wa-color-blue-60) 60%, transparent);
    --border-color-1: var(--wa-color-blue-60);
    --fill-color-2: color-mix(in srgb, var(--wa-color-cyan-60) 60%, transparent);
    --border-color-2: var(--wa-color-cyan-60);
    --fill-color-3: color-mix(in srgb, var(--wa-color-purple-60) 60%, transparent);
    --border-color-3: var(--wa-color-purple-60);
    --fill-color-4: color-mix(in srgb, var(--wa-color-orange-60) 60%, transparent);
    --border-color-4: var(--wa-color-orange-60);
  "
>
</wa-polar-area-chart>
<script type="module">
  const chart = document.querySelector('#polar-colors');

  chart.config = {
    data: {
      labels: ['North', 'South', 'East', 'West'],
      datasets: [{
        label: 'Sales',
        data: [85, 60, 92, 75]
      }]
    }
  };
</script>

Legend

Link to This Section

Use the legend-position attribute to control where the legend appears. Add without-legend to hide it entirely.

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

  chart.config = {
    data: {
      labels: ['Speed', 'Reliability', 'Comfort', 'Safety', 'Efficiency'],
      datasets: [{
        label: 'Rating',
        data: [80, 90, 70, 95, 85]
      }]
    }
  };
</script>

Disabling Tooltips

Link to This Section

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

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

  chart.config = {
    data: {
      labels: ['A', 'B', 'C', 'D'],
      datasets: [{
        label: 'Values',
        data: [40, 70, 55, 85]
      }]
    }
  };
</script>

Disabling Animations

Link to This Section

Use the without-animation attribute to disable chart transitions.

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

  chart.config = {
    data: {
      labels: ['A', 'B', 'C', 'D'],
      datasets: [{
        label: 'Values',
        data: [40, 70, 55, 85]
      }]
    }
  };
</script>
