esri/widgets/smartMapping/ClassedSizeSlider
The ClassedSizeSlider widget is designed for authoring and exploring data-driven visualizations in any layer that can be rendered with size in a ClassBreaksRenderer. At a minimum you must set the breaks property of the widget. The breaks are used to set the slider's thumbs.
See the image below for a summary of the configurable options available on this slider.
The fromRendererResult method can be used to conveniently create this slider from the result of the createClassBreaksRenderer method.
const params = {
layer: layer,
basemap: map.basemap,
valueExpression: "( $feature.POP_POVERTY / $feature.TOTPOP_CY ) * 100",
view: view,
classificationMethod: "equal-interval"
};
let rendererResult = null;
sizeRendererCreator
.createClassBreaksRenderer(params)
.then(function(response) {
rendererResult = response;
layer.renderer = response.renderer;
return histogram({
layer: layer,
valueExpression: params.valueExpression,
view: view,
numBins: 70
});
})
.then(function(histogramResult) {
const slider = ClassedSizeSlider.fromRendererResult(rendererResult, histogramResult);
slider.container = "slider";
})
.catch(function(error) {
console.log("there was an error: ", error);
});
This slider should be used to update the classBreaks in a ClassBreaksRenderer. It is the responsibility of the app developer to set up event listeners on this slider that update the breaks of the appropriate renderer.
// when the user slides the handle(s), update the renderer
// with the updated class breaks
slider.on(["thumb-change", "thumb-drag"], function() {
const renderer = layer.renderer.clone();
renderer.classBreaks = slider.updateClassBreakInfos( renderer.classBreaks );
layer.renderer = renderer;
});

Property Details
-
An array of class breaks with associated sizes. The size mapped to each break should be used to update the renderer of a layer. A minimum of two breaks must be provided to the slider.
- Properties
-
size Number
The size in points of the symbol representing features with values within the given
min
andmax
.max NumberThe max value of the break. The
max
of each break should match themin
value of the break directly above it.min NumberThe min value of the break. The
min
of each break should match themax
value of the break directly below it.
Exampleslider.breaks = [{ min: 0, max: 20, size: 6 }, { min: 20, max: 40, size: 12 }, { min: 40, max: 60, size: 24 }, { min: 60, max: 80, size: 48 }];
-
container
InheritedPropertycontainer String |HTMLElement
Inherited from Widget -
The ID or node representing the DOM element containing the widget. This property can only be set once. The following examples are all valid use case when working with widgets.
Examples// Create the HTML div element programmatically at runtime and set to the widget's container const basemapGallery = new BasemapGallery({ view: view, container: document.createElement("div") }); // Add the widget to the top-right corner of the view view.ui.add(basemapGallery, { position: "top-right" });
// Specify an already-defined HTML div element in the widget's container const basemapGallery = new BasemapGallery({ view: view, container: basemapGalleryDiv }); // Add the widget to the top-right corner of the view view.ui.add(basemapGallery, { position: "top-right" }); // HTML markup <body> <div id="viewDiv"></div> <div id="basemapGalleryDiv"></div> </body>
// Specify the widget while adding to the view's UI const basemapGallery = new BasemapGallery({ view: view }); // Add the widget to the top-right corner of the view view.ui.add(basemapGallery, { position: "top-right" });
-
histogramConfig
InheritedPropertyhistogramConfig HistogramConfig
Inherited from SmartMappingSliderBase -
The Histogram associated with the data represented on the slider. The bins are typically generated using the histogram statistics function.
Examplehistogram({ layer: featureLayer, field: "fieldName", numBins: 30 }).then(function(histogramResult){ // set the histogram to the slider slider.histogramConfig = { bins: histogramResult.bins }; });
-
inputFormatFunction
InheritedPropertyinputFormatFunction LabelFormatter
Inherited from SmartMappingSliderBaseSince: ArcGIS Maps SDK for JavaScript 4.14SmartMappingSliderBase since 4.12, inputFormatFunction added at 4.14. -
A function used to format user inputs. As opposed to labelFormatFunction, which formats thumb labels, the
inputFormatFunction
formats thumb values in the input element when the user begins to edit them.The image below demonstrates how slider input values resemble corresponding slider values by default and won't match the formatting set in
labelFormatFunction
.If you want to format slider input values so they match thumb labels, you can pass the same function set in
labelFormatFunction
toinputFormatFunction
for consistent formatting.However, if an
inputFormatFunction
is specified, you must also write a corresponding inputParseFunction to parse user inputs to understandable slider values. In most cases, if you specify aninputFormatFunction
, you should set the labelFormatFunction to the same value for consistency between labels and inputs.This property overrides the default input formatter, which formats by calling
toString()
on the input value.- See also
Example// Formats the slider input to abbreviated numbers with units // e.g. a thumb at position 1500 will render with an input label of 1.5k slider.inputFormatFunction = function(value, type){ if(value >= 1000000){ return (value / 1000000).toPrecision(3) + "m" } if(value >= 100000){ return (value / 1000).toPrecision(3) + "k" } if(value >= 1000){ return (value / 1000).toPrecision(2) + "k" } return value.toFixed(0); }
-
inputParseFunction
InheritedPropertyinputParseFunction InputParser
Inherited from SmartMappingSliderBaseSince: ArcGIS Maps SDK for JavaScript 4.14SmartMappingSliderBase since 4.12, inputParseFunction added at 4.14. -
Function used to parse slider inputs formatted by the inputFormatFunction. This property must be set if an
inputFormatFunction
is set. Otherwise the slider values will likely not update to their expected positions.Overrides the default input parses, which is a parsed floating point number.
- See also
Example// Parses the slider input (a string value) to a number value understandable to the slider // This assumes the slider was already configured with an inputFormatFunction // For example, if the input is 1.5k this function will parse // it to a value of 1500 slider.inputParseFunction = function(value, type, index){ let charLength = value.length; let valuePrefix = parseFloat(value.substring(0,charLength-1)); let finalChar = value.substring(charLength-1); if(parseFloat(finalChar) >= 0){ return parseFloat(value); } if(finalChar === "k"){ return valuePrefix * 1000; } if(finalChar === "m"){ return valuePrefix * 1000000; } return value; }
-
labelFormatFunction
InheritedPropertylabelFormatFunction LabelFormatter
Inherited from SmartMappingSliderBase -
A modified version of Slider.labelFormatFunction, which is a custom function used to format labels on the thumbs, min, max, and average values. Overrides the default label formatter. This function also supports date formatting.
Example// For thumb values, rounds each label to whole numbers slider.labelFormatFunction = function(value, type) { return (type === "value-change") ? value.toFixed(0): value; }
-
max
InheritedPropertymax Number
Inherited from SmartMappingSliderBase -
The maximum value or upper bound of the slider. If the largest slider value in the constructor is greater than the
max
set in this property, then themax
will update to match the largest slider value.Exampleslider.max = 150;
-
min
InheritedPropertymin Number
Inherited from SmartMappingSliderBase -
The minimum value or lower bound of the slider. If the smallest slider value in the constructor is greater than the
min
set in this property, then themin
will update to match the smallest slider value.Exampleslider.min = -150;
-
precision
InheritedPropertyprecision Number
Inherited from SmartMappingSliderBaseSince: ArcGIS Maps SDK for JavaScript 4.14SmartMappingSliderBase since 4.12, precision added at 4.14. -
Defines how slider thumb values should be rounded. This number indicates the number of decimal places slider thumb values should round to when they have been moved.
This value also indicates the precision of thumb labels when the data range is less than
10
(i.e.(max - min) < 10
).When the data range is larger than
10
, labels display with a precision of no more than two decimal places, though actual slider thumb values will maintain the precision specified in this property.For example, given the default precision of
4
, and the following slider configuration, The labels of the thumbs will display two decimal places, but the precision of the actual thumb values will not be lost even when the user slides or moves the thumb.const slider = new Slider({ min: 20, max: 100, // data range of 80 values: [50.4331], // thumb label will display 50.43 // thumb value will maintain precision, so // value will remain at 50.4331 container: "sliderDiv" });
If the user manually enters a value that has a higher precision than what's indicated by this property, the precision of that thumb value will be maintained until the thumb is moved by the user. At that point, the value will be rounded according to the indicated precision.
If thumb labels aren't visible, they must be enabled with labelInputsEnabled.
Keep in mind this property rounds thumb values and shouldn't be used exclusively for formatting purposes. To format thumb
labels
, use the labelFormatFunction property.- Default Value:4
Exampleslider.precision = 7;
-
state
InheritedPropertystate Stringreadonly
Inherited from SmartMappingSliderBase -
The state of the view model.
Possible Values:"ready" |"disabled"
