17 Feb 202324 minutes to read

By default, gauge will be displayed with an axis. Each axis contains its own ranges, pointers and annotation.

Axis Customization

You can customize the width and color of an axis line by using lineStyle property.
Background for an axis can be customized by using background
property.

<template>
    <div id="app">
        <div class='wrapper'>
           <ejs-circulargauge>
              <e-axes>
                  <e-axis  :lineStyle= 'lineStyle' background= 'rgba(0, 128, 128, 0.3)'>
                  </e-axis>
              </e-axes>
           </ejs-circulargauge>
        </div>
    </div>
</template>

<script>
import Vue from 'vue';
import { CircularGaugePlugin } from "@syncfusion/ej2-vue-circulargauge";

Vue.use(CircularGaugePlugin);
export default {
    data: function () {
        return {
            lineStyle: {
            width: 2,
            color: 'red'
        }
        }
    }
};
</script>
<style>
    .wrapper {
        max-width: 300px;
        margin: 0 auto;
    }
</style>

Angles and Direction

Circular gauge axis can sweep from 0 to 360 degrees. By default start angle of an axis is 200 degree and
end angle is 160 degree and you can customize this option by using
startAngle and endAngle property.

<template>
    <div id="app">
        <div class='wrapper'>
            <ejs-circulargauge :axes = 'axes'>
            </ejs-circulargauge>
        </div>
    </div>
</template>

<script>
import Vue from 'vue';
import { CircularGaugePlugin } from "@syncfusion/ej2-vue-circulargauge";

Vue.use(CircularGaugePlugin);
    export default {
        data: function () {
            return {
                axes: [{
                    startAngle: 270,
                     endAngle: 90
                }]
            }
        }
    };
</script>
<style>
    .wrapper {
        max-width: 300px;
        margin: 0 auto;
    }
</style>

AntiClockWise Direction

The direction property enables you to render the gauge axis either in
ClockWise or in AntiClockWise direction.

<template>
<div id="app">
    <div class='wrapper'>
        <ejs-circulargauge >
            <e-axes>
                <e-axis  direction= 'AntiClockWise'>
                </e-axis>
            </e-axes>
        </ejs-circulargauge>
    </div>
</div>
</template>

<script>
import Vue from 'vue';
import { CircularGaugePlugin } from "@syncfusion/ej2-vue-circulargauge";

Vue.use(CircularGaugePlugin);
export default { };
</script>
<style>
    .wrapper {
        max-width: 300px;
        margin: 0 auto;
    }
</style>

Axis Radius

By default, radius of an axis is calculated based on the available size.
You can customize this, by using radius property.
It takes value either in percentage or in pixel.

In Pixel

You can set the radius of the gauge in pixel as demonstrated below,

<template>
<div id="app">
    <div class='wrapper'>
        <ejs-circulargauge >
            <e-axes>
                <e-axis radius= '150'>
                </e-axis>
            </e-axes>
        </ejs-circulargauge>
    </div>
</div>
</template>

<script>
import Vue from 'vue';
import { CircularGaugePlugin } from "@syncfusion/ej2-vue-circulargauge";

Vue.use(CircularGaugePlugin);
export default { };
</script>
<style>
    .wrapper {
        max-width: 300px;
        margin: 0 auto;
    }
</style>

In Percentage

By setting value in percentage, gauge gets its dimension with respect to its available size.
For example, when the radius is ‘50%’, gauge renders to half of the available size.

<template>
<div id="app">
    <div class='wrapper'>
        <ejs-circulargauge>
            <e-axes>
                <e-axis radius= '50%'>
                </e-axis>
            </e-axes>
        </ejs-circulargauge>
    </div>
</div>
</template>

<script>
import Vue from 'vue';
import { CircularGaugePlugin } from "@syncfusion/ej2-vue-circulargauge";

Vue.use(CircularGaugePlugin);
export default { };
</script>
<style>
    .wrapper {
        max-width: 300px;
        margin: 0 auto;
    }
</style>

Ticks

You can customize the height,
color and
width of major and minor ticks by
using majorTicks
and minorTicks property.
By default, interval for
majorTicks will be calculated automatically
and also you can customize the interval for major and minor ticks using
interval property.

<template>
    <div id="app">
        <div class='wrapper'>
            <ejs-circulargauge >
                <e-axes>
                    <e-axis  :majorTicks= 'majorTicks' :minorTicks= 'minorTicks' >
                    </e-axis>
                </e-axes>
            </ejs-circulargauge>
         </div>
    </div>
</template>

<script>
import Vue from 'vue';
import { CircularGaugePlugin } from "@syncfusion/ej2-vue-circulargauge";

Vue.use(CircularGaugePlugin);
export default {
    data: function () {
    return {
        majorTicks: {
            interval: 10,
            color:'red',
            height: 10,
            width: 3
        },
        minorTicks: {
            interval: 5,
            color:'green',
            height: 5,
            width: 2
        }
    }
    }
};
</script>
<style>
    .wrapper {
        max-width: 300px;
        margin: 0 auto;
    }
</style>

Tick Position

Both minor and major ticks can be moved by using offset and position property. The offset defines the distance between the axis and ticks.
By default, offset value is 0. The position will place the ticks either inside or outside of the axis.
By default, ticks will be placed inside the axis.

<template>
    <div id="app">
        <div class='wrapper'>
            <ejs-circulargauge>
                <e-axes>
                    <e-axis  :majorTicks= 'majorTicks' :minorTicks= 'minorTicks'>
                    </e-axis>
                </e-axes>

            majorTicks: {
                interval: 10,
                color:'red',
                height: 10,
                width: 3,
                position: 'Inside',
                offset: 5
            },
            minorTicks: {
                interval: 5,
                color:'green',
                height: 5,
                width: 2,
                position: 'Inside',
                offset: 5
            }
        }
    }
};
</script>
<style>
    .wrapper {
        max-width: 300px;
        margin: 0 auto;
    }
</style>

Labels

Labels of an axis can be customized by using font property in labelStyle options.

<template>
    <div id="app">
        <div class='wrapper'>
            <ejs-circulargauge>
                <e-axes>

Label Position

Labels can be moved by using offset or
position property.
The offset defines the distance between the labels and ticks.
By default, offset value is 0.
The position will place the labels either inside or outside of the axis.
By default, labels will be placed inside the axis.

<template>
    <div id="app">

</style>

Display the last label, even if it isn’t in the visible range**

If the last label is not in the visible range, it will be hidden by default. If you want to show the last label, set the showLastLabel property to true in the axes API of circular gauge.

<template>
    <div id="app">
        <div class='wrapper'>
            <ejs-circulargauge>

  .wrapper {
    max-width: 300px;
    margin: 0 auto;
  }
</style>

Auto Angle

Labels can be swept along the axis angle by enabling autoAngle property.

<template>
     <div id="app">
         <div class='wrapper'>
             <ejs-circulargauge>
                 <e-axes>

    .wrapper {
        max-width: 300px;
        margin: 0 auto;
    }
</style>

Smart Labels

When an axis makes a complete circle, then the first and last label of the axis will get overlap with each other.
In this scenario, you can either hide 1st or last label using hiddenLabel property.
When hiddenLabel value is First,
then the 1st label will be hidden and when the
hiddenLabel value is ‘Last’,
then the last label will be hidden.

<template>
    <div id="app">
        <div class='wrapper'>

Label Format

Axis labels can be formatted by using format property in labelStyle and its supports all globalize format.

<template>
    <div id="app">
        <div class='wrapper'>
            <ejs-circulargauge>
                <e-axes>
                    <e-axis :labelStyle ='labelStyle'>
                    </e-axis>
                </e-axes>
            </ejs-circulargauge>
        </div>
    </div>
</template>
<script>
import Vue from 'vue';
import { CircularGaugePlugin } from "@syncfusion/ej2-vue-circulargauge";

Vue.use(CircularGaugePlugin);
export default {
    data: function () {
    return {
        labelStyle: {
            format: 'p1'
        }
    }
    }
};
</script>
<style>
    .wrapper {
        max-width: 300px;

Multiple Axes

Each axis will have its own ranges, pointers, annotations and customization options.
