animation

Specifies animation properties.

Selector: DxAnimation
Type: any

To make your gauge "live", enable animation for it by setting the enabled property of the animation object to true. In this instance, the gauge indicators will appear in motion. In addition, within the animation object, you can set an appropriate easing mode using the easing property and specify how long the animation should run using the duration property.

jQuery
index.js
$(function() {
    $("#barGaugeContainer").dxBarGauge({
        // ...
        animation: {
            easing: "linear",
            duration: 500
        }
    });

backgroundColor

Specifies a color for the remaining segment of the bar's track.

Selector: background-color
Type:

String

Default Value: '#e0e0e0'

BarGauge displays values in the form of several circular bars each placed on a separate track. Since a bar indicates a value, it occupies only a segment of this track. The remaining segment is drawn in the color specified by the backgroundColor property.

This property supports the following colors:

barSpacing

Specifies a distance between bars in pixels.

Selector: bar-spacing
Type:

Number

Default Value: 4

baseValue

Specifies a base value for bars.

Selector: base-value
Type:

Number

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.

Selector: center-template
Type:

template

Template Data:

BarGauge

The UI component's instance.

Default Name: 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;
}

paletteExtensionMode

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

Selector: palette-extension-mode
Type:

PaletteExtensionMode

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.

pathModified

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

Selector: path-modified
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.

Selector: redraw-on-resize
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.

relativeInnerRadius

Defines the radius of the bar that is closest to the center relatively to the radius of the topmost bar.

Selector: relative-inner-radius
Type:

Number

Default Value: 0.3

This property accepts values from the (0, 1) range.

resolveLabelOverlapping

Specifies how the UI component should behave when bar labels overlap.

Selector: resolve-label-overlapping
Type:

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.

Selector: rtl-enabled
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.

size

Specifies the UI component's size in pixels.

Selector: DxSize
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,

$(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.

Selector: start-value
Type:

Number

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.

Selector: DxTitle
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.

Selector: DxTooltip
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.
