import * as histogram from "@arcgis/core/smartMapping/statistics/histogram.js";

const histogramResult = await histogram.histogram({
  layer: featureLayer,
  field: "population",
  numBins: 30,
});

const slider = new HistogramRangeSlider({
  bins: histogramResult.bins,

  excludedBarColor: "#d7d7d7",
  rangeType: "between",
  labelFormatFunction: (value) => "$" + Math.round(value).toLocaleString(),

});

// Filter layer when slider values change
slider.on(["thumb-change", "thumb-drag", "segment-drag"], () => {
  const [min, max] = slider.values;
  featureLayer.definitionExpression = `${fieldName} >= ${min} AND ${fieldName} <= ${max}`;
});

HistogramRangeSlider Configuration

const slider = new HistogramRangeSlider({
  bins: histogramResult.bins,
  min: 0,
  max: 100,
  values: [20, 80],

• widgets-scalebar - ScaleBar widget configuration
• histogram-range-slider - Histogram range slider for filtering

Common Pitfalls

1. Track widget requires HTTPS: Track and Locate use the Geolocation API, which only works on HTTPS origins (or localhost). They fail silently on HTTP.
2. FloorFilter needs floor-aware web map: Requires a web map configured with floor-aware data including facility and level information. A standard web map will not display anything.
3. BuildingExplorer only works with BuildingSceneLayer in SceneView: Requires both a 3D SceneView (not MapView) and at least one BuildingSceneLayer. It will not work with other layer types or in 2D.
4. HistogramRangeSlider needs valid bins: The bins property must be an array of objects with minValue, maxValue, and count properties. Use smartMapping/statistics/histogram to generate valid bins from layer data.
5. Missing reference-element on external components: When placing widget components outside the map/scene element (e.g., in a Calcite panel), set the reference-element attribute to the map/scene element ID.
