JavaScript/jQuery BarGauge Options

Default Value: 4

baseValue

Specifies a base value for bars.

Type:

Default Value: 0

Cannot be used in themes.

By default, all bars start from the beginning of the gauge's scale. If you need to draw them starting from a specific scale value, assign the required value to the baseValue property. In this instance, each bar will display the range from the baseValue to the corresponding value specified to this bar.

centerTemplate

Specifies a custom template for content in the component's center.

Type:

template

| undefined

Function parameters:

component:

BarGauge

The UI component's instance.

element:

SVGGElement

An empty SVGGElement that acts as a container for the template content.

Return Value:

String

|

SVGElement

|

jQuery

One of the following:

SVG markup as a string
An SVGElement
SVG markup wrapped in a jQuery element

Default Value: undefined

You need to render template content as an SVG element. The following code snippet shows how to specify a custom template for content in the BarGauge's center:

jQuery

$(function(){
    $("#barGaugeContainer").dxBarGauge({
        // ...
        centerTemplate: (gauge, container) => {
            const rect = createRect(50, 50, 'transparent');
            const text = createText(10, 200, 12, 'start', gauge.value());

            container.appendChild(rect);
            container.appendChild(text);
        },
    });
});

function createRect(width, height, fill) {
    const rect = document.createElementNS('http://www.w3.org/2000/svg', 'rect');

    rect.setAttribute('x', 0);
    rect.setAttribute('y', 0);
    rect.setAttribute('width', width);
    rect.setAttribute('height', height);
    rect.setAttribute('fill', fill);

    return rect;
}

function createText(x, y, fontSize, textAnchor, content) {
    const text = document.createElementNS('http://www.w3.org/2000/svg', 'text');

    text.setAttribute('x', x);
    text.setAttribute('y', y);
    text.setAttribute('fill', '#000');
    text.setAttribute('text-anchor', textAnchor);
    text.setAttribute('font-size', fontSize);

    text.textContent = content;

    return text;
}

ShiftLabelOverlap

Default Value: 'hide'

If a BarGauge displays several values close to each other, the corresponding labels may overlap. If you want to avoid overlapped labels, use the resolveLabelOverlapping property to specify how the gauge adjusts label position or visibility. The following values are available:

'hide'
The gauge hides labels with smaller values except for the label with the smallest value.
'shift'
The gauge shifts labels. If the component's size is not big enough to accommodate all labels, the BarGauge hides labels with the smallest values.
'none'
Labels overlap.

rtlEnabled

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

Type:

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.

size

Specifies the UI component's size in pixels.

Type: viz/core/base_widget:BaseWidgetSize

Default Value: {height: 300, width: 300}

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.

jQuery

index.js

$(function() {
    $("#barGaugeContainer").dxBarGauge({
        // ...
        size: {
            height: 300,
            width: 600
        }
    });
});

Angular

app.module.ts

<dx-bar-gauge ... >
    <dxo-size
        [height]="300"
        [width]="600">
    </dxo-size>
</dx-bar-gauge>

import { Component } from '@angular/core';

@Component({
    selector: 'app-root',

App.js

import React from 'react';

import BarGauge, {

} from 'devextreme-react/bar-gauge';

class App extends React.Component {
    render() {
        return (

export default App;

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

jQuery

index.js

styles.css

$(function() {
    $("#barGauge").dxBarGauge({
        // ...
    });
});

#barGauge {
    width: 85%;
    height: 70%;
}

Angular

app.component.html

app.styles.css

<dx-bar-gauge ...
    id="barGauge">
</dx-bar-gauge>

#barGauge {
    width: 85%;
    height: 70%;
}

Vue

App.vue

<template>
    <DxBarGauge ...
        id="barGauge">
    </DxBarGauge>
</template>

<script>
import DxBarGauge from 'devextreme-vue/bar-gauge';

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

<style>
#barGauge {
    width: 85%;
    height: 70%;
}
</style>

React

App.js

styles.css

import React from 'react';

import BarGauge from 'devextreme-react/bar-gauge';

class App extends React.Component {
    render() {
        return (
            <BarGauge ...
                id="barGauge">
            </BarGauge>
        );
    }
}
export default App;

#barGauge {
    width: 85%;
    height: 70%;
}

startValue

Specifies a start value for the gauge's invisible scale.

Type:

Default Value: 0

Cannot be used in themes.

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.

tooltip

Configures tooltips.

Type:

Tooltip

A tooltip is a miniature rectangle displaying the value of a gauge's bar. A tooltip appears when the end-user hovers the cursor over a bar. You can enable/disable tooltips, change their appearance and format their text using fields of the tooltip configuration object.

values

Specifies the array of values to be indicated on a bar gauge.

Type:

Array<Number>

Default Value: []

Raised Events: onOptionChanged

Cannot be used in themes.

Apart from specifying an array of values when configuring the BarGauge UI component, you can obtain this array at runtime using the values() method, and change it using the values(newValues) method.
