JavaScript/jQuery Funnel Options

This section describes properties that configure the Funnel UI component's contents, behavior and appearance.

adaptiveLayout

Specifies adaptive layout properties.

Type:

Object

The adaptive layout enables the UI component to hide optional elements if they do not fit in the container. Elements are hidden in the following sequence:

  1. Title
  2. Export menu icon
  3. Legend
  4. Item labels (can be saved by setting the adaptiveLayout.keepLabels property to true)

Use the height and width properties in the adaptiveLayout object to specify the minimum container size at which the layout begins to adapt.

algorithm

Specifies the algorithm for building the funnel.

Default Value: 'dynamicSlope'

Two algorithms are available:

  • "dynamicSlope"

    Each funnel item's form depends on the ratio between the current and the next item's value.

  • "dynamicHeight"

    The height of each funnel item is proportional to the item's value. This algorithm produces a pyramid which is upturned by default. You can return it to normal by assigning true to the inverted property. You can also transform the pyramid's peak into a funnel's neck using the neckHeight and neckWidth properties.

See Also

argumentField

Specifies which data source field provides arguments for funnel items. The argument identifies a funnel item and represents it on the legend.

Type:

String

Default Value: 'arg'

colorField

Specifies which data source field provides colors for funnel items. If this field is absent, the palette provides the colors.

Type:

String

Default Value: 'color'

The colors must have one of the following formats:

dataSource

Binds the UI component to data.

Cannot be used in themes.

The Funnel works with collections of objects.

Depending on your data source, bind Funnel to data as follows. In each case, also specify the argumentField, valueField, and optionally colorField properties.

  • Data Array
    Assign the array to the dataSource option. View Demo

  • Read-Only Data in JSON Format
    Set the dataSource property to the URL of a JSON file or service that returns JSON data.

  • OData
    Implement an ODataStore.

  • Web API, PHP, MongoDB
    Use one of the following extensions to enable the server to process data according to the protocol DevExtreme UI components use:

    Then, use the createStore method to configure access to the server on the client as shown below. This method is part of DevExtreme.AspNet.Data.

  • Any other data source
    Implement a CustomStore.

Regardless of the data source on the input, the Funnel always wraps it in the DataSource object. This object allows you to sort, filter, group, and perform other data shaping operations. To get its instance, call the getDataSource() method.

NOTE

Review the following notes about data binding:

  • If you wrap the store into the DataSource object explicitly, set the paginate property to false to prevent data from partitioning.

  • Data field names cannot be equal to this and should not contain the following characters: ., :, [, and ].

jQuery
  • The stores are immutable. You cannot change their configurations at runtime. Instead, create a new store or DataSource and assign it to the dataSource property as shown in the following help topic: Get and Set Properties.
Angular
  • The stores are immutable. You cannot change their configurations at runtime. Instead, create a new store or DataSource and assign it to the dataSource property as shown in the following help topic: Two-Way Property Binding.
Vue
  • The stores are immutable. You cannot change their configurations at runtime. Instead, create a new store or DataSource and assign it to the dataSource property as shown in the following help topic: Two-Way Property Binding.
React
  • The stores are immutable. You cannot change their configurations at runtime. Instead, create a new store or DataSource and assign it to the dataSource property as shown in the following help topic: Controlled Mode.

onSelectionChanged

A function that is executed when a funnel item is selected or selection is canceled.

Type:

Function

Function parameters:

Information about the event.

Object structure:
Name Type Description
component

Funnel

The UI component's instance.

element

HTMLElement | jQuery

The UI component's container. It is an HTML Element or a jQuery Element when you use jQuery.

item

Funnel Item

The Item object.

Default Value: null
Cannot be used in themes.

To identify whether the selection has been applied or canceled, call the funnel item's isSelected() method.

See onItemClick to learn how to implement selection.

See Also

palette

Sets the palette to be used to colorize funnel items.

Type:

Array<String>

|

Palette

Default Value: 'Material'

This property accepts either the name of a predefined palette or an array of colors. The array can include the following colors:

See Also

paletteExtensionMode

Specifies what to do with colors in the palette when their number is less than the number of funnel items.

Default Value: 'blend'

The following variants are available:

  • "blend"
    Create a blend of two neighboring colors and insert it between these colors in the palette.

  • "alternate"
    Repeat the full set of palette colors, alternating their normal, lightened, and darkened shades in that order.

  • "extrapolate"
    Repeat the full set of palette colors, changing their shade gradually from dark to light.

View Demo

pathModified

Notifies the UI component that it is embedded into an HTML page that uses a tag modifying the path.

Type:

Boolean

Default Value: false
Cannot be used in themes.

If you place the UI component on a page that uses a tag modifying the path (<base>, <iframe>, etc.), some of the UI component elements may get mixed up or disappear. To solve this problem, set the pathModified property to true.

See Also

redrawOnResize

Specifies whether to redraw the UI component when the size of the container changes or a mobile device rotates.

Type:

Boolean

Default Value: true
Cannot be used in themes.

When this property is set to true, the UI component will be redrawn automatically in case the size of its container changes.

resolveLabelOverlapping

Specifies how item labels should behave when they overlap.

Default Value: 'shift'

The following modes are available:

  • "shift"
    Item labels shift from their positions. If they still overlap, some of them hide.

  • "hide"
    Certain item labels hide.

  • "none"
    Item labels overlap.

See Also

rtlEnabled

Switches the UI component to a right-to-left representation.

Type:

Boolean

Default Value: false
Cannot be used in themes.

When this property is set to true, the UI component text flows from right to left, and the layout of elements is reversed. To switch the entire application/site to the right-to-left representation, assign true to the rtlEnabled field of the object passed to the DevExpress.config(config) method.

JavaScript
DevExpress.config({
    rtlEnabled: true
});
NOTE
In a right-to-left representation, SVG elements have the direction attribute with the rtl value. This might cause problems when rendering left-to-right texts. Use this property if you have only right-to-left texts.

selectionMode

Specifies whether a single or multiple funnel items can be in the selected state at a time. Assigning "none" disables the selection feature.

Default Value: 'single'

See onItemClick to learn how to implement selection.

size

Specifies the UI component's size in pixels.

Type: viz/core/base_widget:BaseWidgetSize
Default Value: {height: 400, width: 400}

You can specify a custom width and height for the component:

Fixed Relative
Assign values to the size object's height and width properties or specify a container for the component. Specify a container for the component. The component occupies the container area.
NOTE
The size object has priority over the container.

Assign 0 to the size object's height and width properties to hide the component.

jQuery
index.js
$(function() {
    $("#funnelContainer").dxFunnel({
        // ...
        size: {
            height: 300,
            width: 600
        }
    });

                />
            </Funnel>
        );
    }
}
export default App;

Alternatively, you can use CSS to style the UI component's container:

jQuery
index.js
styles.css
$(function() {
    $("#funnel").dxFunnel({
        // ...
    });
});
#funnel {
    width: 85%;
    height: 70%;
}
Angular
app.component.html
app.styles.css
<dx-funnel ...
    id="funnel">
</dx-funnel>
#funnel {
    width: 85%;
    height: 70%;
}
Vue
App.vue
<template>
    <DxFunnel ...
        id="funnel">
    </DxFunnel>
</template>

<script>
import DxFunnel from 'devextreme-vue/funnel';

export default {
    components: {
        DxFunnel
    },
    // ...
}
</script>

<style>
#funnel {
    width: 85%;
    height: 70%;
}
</style>
React
App.js
styles.css
import React from 'react';

import Funnel from 'devextreme-react/funnel';

class App extends React.Component {
    render() {
        return (
            <Funnel ...
                id="funnel">
            </Funnel>
        );
    }
}
export default App;
#funnel {
    width: 85%;
    height: 70%;
}

sortData

Specifies whether to sort funnel items.

Type:

Boolean

Default Value: true

true puts bigger values on the top, smaller on the bottom; false keeps the order specified in the data source.

See Also

theme

Sets the name of the theme the UI component uses.

Type:

Theme

Default Value: 'generic.light'

A theme is a UI component configuration that gives the UI component a distinctive appearance. You can use one of the predefined themes or create a custom one. Changing the property values in the UI component's configuration object overrides the theme's corresponding values.

title

Configures the UI component's title.

Type: viz/core/base_widget:BaseWidgetTitle

The UI component's title is a short text that usually indicates what is visualized. If you need to specify the title's text only, assign it directly to the title property. Otherwise, set this property to an object with the text and other fields specified.

The title can be accompanied by a subtitle elaborating on the visualized subject using the title.subtitle object.

valueField

Specifies which data source field provides values for funnel items. The value defines a funnel item's area.

Type:

String

Default Value: 'val'
