Scatter Chart

<wa-scatter-chart> Since 3.3 Experimental Pro Scatter-chart requires access to Web Awesome Pro

Scatter charts reveal relationships between two variables by plotting data points on a grid. They are ideal for identifying correlations, clusters, and outliers in datasets.

Scatter chart data uses {x, y} objects instead of simple arrays. Each data point must include both an x and y value.

<wa-scatter-chart id="scatter-hero" label="Height vs. Weight" description="A scatter chart showing the relationship between height and weight">
</wa-scatter-chart>
<script type="module">
  const chart = document.querySelector('#scatter-hero');

  chart.config = {
    data: {
      datasets: [{
        label: 'Measurements',
        data: [
          { x: 158, y: 55 },
          { x: 163, y: 62 },
          { x: 165, y: 68 },
          { x: 170, y: 72 },
          { x: 173, y: 75 },
          { x: 175, y: 80 },
          { x: 178, y: 78 },
          { x: 180, y: 85 },
          { x: 183, y: 82 },
          { x: 188, y: 90 }
        ]
      }]
    }
  };
</script>

For advanced configuration such as mixed chart types, 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-scatter-chart id="scatter-js-example" label="Test Results" description="A scatter chart of study hours vs. scores">
</wa-scatter-chart>
<script type="module">
  const chart = document.querySelector('#scatter-js-example');

  chart.config = {
    data: {
      datasets: [{
        label: 'Students',
        data: [
          { x: 2, y: 65 },
          { x: 3, y: 72 },
          { x: 4, y: 78 },
          { x: 5, y: 82 },
          { x: 6, y: 88 },
          { x: 7, y: 85 },
          { x: 8, y: 92 },
          { x: 9, y: 95 }
        ]
      }]
    }
  };
</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. Each data point is an object with x and y properties.

<wa-scatter-chart label="Test Results" description="A scatter chart showing the correlation between study hours and test scores">
  <script type="application/json">
    {
      "data": {
        "datasets": [{
          "label": "Students",
          "data": [
            {"x": 2, "y": 65},
            {"x": 3, "y": 72},
            {"x": 4, "y": 78},
            {"x": 5, "y": 82},
            {"x": 6, "y": 88},
            {"x": 7, "y": 85},
            {"x": 8, "y": 92},
            {"x": 9, "y": 95}
          ]
        }]
      }
    }
  </script>
</wa-scatter-chart>

Multiple Datasets

Use multiple datasets to compare groups. Each dataset is plotted in its own color.

<wa-scatter-chart id="scatter-multi" label="Group Comparison" description="A scatter chart comparing test results between two study groups">
</wa-scatter-chart>
<script type="module">
  const chart = document.querySelector('#scatter-multi');

  chart.config = {
    data: {
      datasets: [
        {
          label: 'Group A',
          data: [
            { x: 3, y: 70 },
            { x: 4, y: 75 },
            { x: 5, y: 82 },
            { x: 6, y: 85 },
            { x: 7, y: 90 }
          ]
        },
        {
          label: 'Group B',
          data: [
            { x: 2, y: 60 },
            { x: 4, y: 68 },
            { x: 5, y: 74 },
            { x: 7, y: 80 },
            { x: 8, y: 88 }
          ]
        }
      ]
    }
  };
</script>

Custom Colors

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

<wa-scatter-chart
  id="scatter-colors"
  label="Custom Colors"
  description="A scatter chart with custom point colors"
  style="
    --fill-color-1: var(--wa-color-cyan-60);
    --border-color-1: var(--wa-color-cyan-60);
  "
>
</wa-scatter-chart>
<script type="module">
  const chart = document.querySelector('#scatter-colors');

  chart.config = {
    data: {
      datasets: [{
        label: 'Observations',
        data: [
          { x: 10, y: 30 },
          { x: 20, y: 50 },
          { x: 30, y: 45 },
          { x: 40, y: 70 },
          { x: 50, y: 65 },
          { x: 60, y: 80 }
        ]
      }]
    }
  };
</script>

Point Radius

Use the --point-radius CSS custom property to control the size of each plotted dot.

<wa-scatter-chart id="scatter-points" style="--point-radius: 8px" label="Large Points" description="A scatter chart with larger data point dots">
</wa-scatter-chart>
<script type="module">
  const chart = document.querySelector('#scatter-points');

  chart.config = {
    data: {
      datasets: [{
        label: 'Observations',
        data: [
          { x: 10, y: 30 },
          { x: 20, y: 50 },
          { x: 30, y: 45 },
          { x: 40, y: 70 },
          { x: 50, y: 65 },
          { x: 60, y: 80 }
        ]
      }]
    }
  };
</script>

Legend

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

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

  chart.config = {
    data: {
      datasets: [
        {
          label: 'Morning',
          data: [
            { x: 6, y: 15 },
            { x: 7, y: 22 },
            { x: 8, y: 30 },
            { x: 9, y: 28 }
          ]
        },
        {
          label: 'Afternoon',
          data: [
            { x: 12, y: 45 },
            { x: 13, y: 52 },
            { x: 14, y: 48 },
            { x: 15, y: 40 }
          ]
        }
      ]
    }
  };
</script>

Grid Lines

Use the grid attribute to control which axes show grid lines. Options are both (default), x, y, and none.

<wa-scatter-chart id="scatter-grid" grid="none" label="No Grid" description="A scatter chart with grid lines hidden">
</wa-scatter-chart>
<script type="module">
  const chart = document.querySelector('#scatter-grid');

  chart.config = {
    data: {
      datasets: [{
        label: 'Points',
        data: [
          { x: 10, y: 20 },
          { x: 25, y: 50 },
          { x: 40, y: 35 },
          { x: 55, y: 70 },
          { x: 70, y: 55 }
        ]
      }]
    }
  };
</script>

Axis Labels

Use the x-label and y-label attributes to add descriptive labels to each axis.

<wa-scatter-chart id="scatter-axis" x-label="Hours Studied" y-label="Score" label="Study Correlation" description="A scatter chart with labeled axes showing study hours vs. score">
</wa-scatter-chart>
<script type="module">
  const chart = document.querySelector('#scatter-axis');

  chart.config = {
    data: {
      datasets: [{
        label: 'Students',
        data: [
          { x: 1, y: 55 },
          { x: 3, y: 68 },
          { x: 5, y: 78 },
          { x: 7, y: 88 },
          { x: 9, y: 94 }
        ]
      }]
    }
  };
</script>

Disabling Tooltips

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

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

  chart.config = {
    data: {
      datasets: [{
        label: 'Data',
        data: [
          { x: 5, y: 10 },
          { x: 15, y: 30 },
          { x: 25, y: 20 },
          { x: 35, y: 40 },
          { x: 45, y: 35 }
        ]
      }]
    }
  };
</script>

Disabling Animations

Use the without-animation attribute to disable chart transitions.

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

  chart.config = {
    data: {
      datasets: [{
        label: 'Data',
        data: [
          { x: 5, y: 10 },
          { x: 15, y: 30 },
          { x: 25, y: 20 },
          { x: 35, y: 40 },
          { x: 45, y: 35 }
        ]
      }]
    }
  };
</script>
