A Vue.js component to create beautiful animated circular progress bars


A dependency-free Vue.js plugin to create beautiful and animated circular progress bars, implemented with SVG. The purpose of this plugin is to combine the best properties of other available libraries and to add unique features, delivered in a simple to use component with friendly interface.

With the available options you can create simple circles very quickly. But playing with the combinations of props and with a bit of imagination you can create really exciting things.



Install the library via npm:

npm i vue-ellipse-progress

The component is provided as a Vue.js plugin. So just initialize it in your main.js:

import VueEllipseProgress from 'vue-ellipse-progress';


// Vue.use(VueEllipseProgress, "vep"); you can define a name and use the plugin like <vep/>

Now use the component:

  lineMode="in 10"
  dash="60 0.9"
  animation="reverse 700 400"
  dot="10 blue"
  <span slot="legend-value">/200</span>
  <p slot="legend-caption">GOOD JOB</p>


You are ready to go with just following line:

<vue-ellipse-progress :progress="progress"/>

The progress is the only required property. However, in order to create unique circles that match your design needs, you can use all the properties explained below.

This table below provides a quick overview over all available options. To gain more information in general and concerning the creation of exclusive circles please read below the table.

:grey_exclamation: Also make sure to check slot options

  • progress

Animated: :heavy_check_mark:

Is any Number from 0 to 100 (including decimals). This property defines the filled area from progress circle line in
percent. progress is animated and counts up or down on any value changes with duration defined in
animation.duration property. The progress is shown by default as the legend in the middle of the circle.

Example: :scroll:
<vue-ellipse-progress :progress="myProgress" />
this.myProgress = 55.5;
this.myProgress = this.tasksDone * 100 / maxTasks; // the percentage of done tasks

:heavy_exclamation_mark: The progress is always used to fill the progress circle line. So you cannot customize this value. All values below 0 and above 100 are ignored and not valid Numbers always lead to noData state. For customization purpose please use legendValue.

If legendValue is defined the progress will NOT be displayed as circle legend.

  • size

Animated: :heavy_check_mark:

Is any number from >=0. It defines the width and height of the circle. The calculation of the circumference of the circle depends on the properties lineMode, thickness, emptyThickness and dot, so the circle never exceeds the size value!

:heavy_exclamation_mark: Check lineMode property to understand how the progress circle behaves depending on the line mode and offset.

  • line

Animated: :heavy_check_mark:

Is a string value from round | square | butt. Defines the progress circle line cap. Internally is used the CSS property stroke-linecap.

Example: :scroll:


  • thickness

Animated: :heavy_check_mark:

Is any number or percent value >=0. It defines the progress circle line thickness. If you define the value in percent, the thickness will be calculated in relation to size. Internally is used the CSS property stroke-width.

  • lineMode

Animated: :heavy_check_mark:

Descriptive string in form "mode [offset]" that defines how the progress line is aligned in relation to empty line. The first value ist the mode and the optional second is the offset. You can understand the modes as the presets that help you to align lines as you want to.

  • mode:

    • normal: this is the default value and both lines are aligned at the base line (centered).

    • in: the progress line is inside the empty circle

    • in-over: the progress line is both inside the empty circle and overlaps the empty circle

    • out: the progress line is outside the empty circle

    • out-over: the progress line is both outside the empty circle and overlaps the empty circle

    • bottom: the progress line is aligned at the bottom of the empty circle

    • top: the progress line is aligned at the top of the empty circle

  • offset: is any negative or positive number and defines the distance between the progress and empty lines. It can be only combined with the in and out modes

Example: :scroll:

Let's take a look at few examples

line-mode="in 10" line-mode="in 10" line-mode="out 10" line-mode="out 15"

As you can see the second and fourth examples are similar to the modes bottom and top. Only with the modes in and out and the offset you can achieve the same result. But the provided modes like a presets take care about annoying calculations and do the job for you.

  • emptyThickness

Animated: :heavy_check_mark:

Is any number or percent value >=0. It defines the empty circle line thickness. If you define the value in percent, thickness will be calculated in relation to size. Internally is used the CSS property stroke-width.

  • color

Animated: :heavy_check_mark:

Defines the color of progress circle line. Is any CSS color like #123 or lime or an object that defines the gradient.

  • color="#3f79ff" - as String

  • :color="{ colors [, radial ]}" - as Object

    • radial - default false. Defines whether the gradient is radial or linear
    • colors - Array that contains the gradient colors as objects { color: "#6546f7", offset: 0 [, opacity: 1] }
Example: :scroll:

Now you are ready for an example:

gradient: {
    radial: false,
    colors: [
        color: '#6546f7',
        offset: 0,
        opacity: '1',
        color: 'lime',
        offset: 100,
        opacity: '0.6',

  • colorFill

Animated: :heavy_check_mark:

Defines the fill color of the progress circle. Takes the same value as color

  • emptyColor

Animated: :heavy_check_mark:

Defines the color of the empty circle line. Takes the same value as color

  • emptyColorFill

Animated: :heavy_check_mark:

Defines the fill color of the empty circle. Takes the same value as color

  • legend

Is a Boolean. It defines whether the progress or from you defined legendValue is displayed as the legend of the circle.

  • legendValue

Animated: :heavy_check_mark:

Is any number. Use this property if you want to customize the shown progress as the legend of the circle. If defined, legendValue will replace progress as the circle legend!

npm You can set any precision of the decimal numbers. If the prop is defined as a string, you can specify the "," as decimals separator (e.g "123,123" for german numbers).

Example: :scroll:

Let's say you need to display a rating from 0 to 5 of a product with 3.5 stars. Since progress can take values only from 0 to 100 your need an additional property legendValue. You can show the product rating like in the following example:

<vue-ellipse-progress progress="progress" :legend-value="rating" />
this.rating = 3.5;
this.progress = this.rating * 100 / 5; // the rating percentage

Now you can display custom progress value that still animated and circle progress fills properly!

legend-value="345,12345" // set "," as delimiter defining the value as string

:heavy_exclamation_mark: note that legendValue replaces progress as circle legend but not vice versa.

  • animation

Descriptive string in form "type [duration delay]" that defines the initial animation of progress circle line filling. type is one from predefined animations and the optional duration and delay are number values. Note that the order is important and that you can only define the delay after duration.

  • type - is one of the predefined animations: default | rs | reverse | bounce| loop
  • duration - number in milliseconds, default 1000
  • delay - number in milliseconds, default 400
Example: :scroll:
animation="rs 700 200"
animation="bounce 1000"

  • loading

Forces loading state. The component provides an indeterminate loading state for the case that your data is not available immediately. With this property set to true you can use the component as the indeterminate progress.

  • determinate

Provides a determinate loading state that indicates that your data loading is still in progress but allows to show the progress.

  • noData

Animated: :heavy_check_mark:

Forces no data state. The component provides a no data state for the case that your data is not available. The circle progress is still empty.

:heavy_exclamation_mark: The component will take the no data state even if you provide an invalid progress value

  • angle

Animated: :heavy_check_mark:

Is any number. It defines the starting point of the progress circle line.

  • fontSize

Animated: :heavy_check_mark:

Is any valid CSS size value. It defines the font size of the circle legend. You will have to use legendClass if you want to apply more specific styles.

  • fontColor

Animated: :heavy_check_mark:

Is any valid CSS color value. It defines the color of the circle legend. You will have to use legendClass if you want to apply more specific styles.

  • legendClass

Adds class to the circles legend to give you the possibility to style it.

  • dash

Animated: :heavy_check_mark:

Descriptive string in form "[strict] count spacing" that adds dashed empty progress line. This property provides the optional strict mode. In this mode you can define the explicit number of dashes as count with the given relative spacing as number in range >= 0 and < 1. Without strict the default behavior of the SVG stroke-dasharray property is used, where the size and spacings of the dashes are defined.

Example: :scroll:

dash="strict 60 0.5" - 60 dashes with 0.5 relative spacing

dash="10 10" - 10 pixels big dashes with 10 pixels spacing, the number of dashes depends on the empty circle circumference

  • half

Boolean value that specifies the type of the circle. If it is set to true, only the half of the circle will be drawn like a gauge chart.

Example: :scroll:

  • dot


Animated: :heavy_check_mark:

The dot property lets you define a point indicator at the end of the progress line. You have a lot of freedom to customize the dot using a Number, descriptive String, or an Object to inject any CSS styles.

Number: :dot="10" - specifies a round dot with 10px width and height and default #713dfd color

Descriptive string: dot="size [color]" - size can be just a Number or a percent value like 5%, the calculation for percent values is similar to thickness and depends on the size. color is optional and lets you quickly define the color of the dot. The order of properties is important for parsing the String and you can set the color only if the size is defined.

Object: :dot="{ size: Number | String [, any CSS inline style with Vue syntax] }" - to customize the point, you can define the prop as an Object. size is required and can be just a Number or a String to define a percent value. Only defining the prop as an Object you have the possibility to add any styles to the dot you want to, using Vue syntax for defining inline styles, you can even completely break the positioning of the dot, if you need. You cannot override the height of the dot since it is important for internal calculation and must be controllable.

Example: :scroll:

The examples will provide more clarity

:dot="10" // just a Number defining size in pixel
dot="10" // the same as above
dot="10%" // 10% from the circle size will be converted to pixel
dot="5% red" // adds red dot
// defines same dot as above
  size: "5%", // required
  backgroundColor: "red", // add any inline CSS using Vue syntax
  left: "10px", // you can even move the dot, but it is not recommended
dot example
  • data

You can specify 2 or more circles as objects in an array as data. For each circle you can use almost every available property. It is not necessary to specify all properties, they will be merged with global props and the specified props will overwrite the global. The circles are rendered inside each other.

:heavy_exclamation_mark: Excluded props: lineMode, emptyThickness, legend. These properties will be ignored, if data is specified. The legend of this circle is also not shown.

Example: :scroll:
<!-- this props are applied to all circles, if not overwritten in "data"-->
<vue-ellipse-progress color="blue" animation="loop 500" ...  :data="data"/>

data: [
    progress: 50, // required for each circle
    color: "red",  // will overwrite global progress color
    ...           // other options will be merged with global
    progress: 50, // required for each circle
    animation: "rs 1500 500"  // you can set almost any option that will be specific to this circle

  • gap

Animated: :heavy_check_mark:

Defines the gap in pixels from one circle to the previous circle. It will be applied only if data prop is used.

Example: :scroll:
<vue-ellipse-progress :gap="10"/>

Slot options

  • legend-value

In this slot you can put an additional element that you want to display beside the progress

  • legend-caption

In this slot you can put any HTML and style it on your own. This slot is aligned below the progress.

Example: :scroll:

This code ...

<vue-ellipse-progress ....>
    <span slot="legend-value">/200</span>
    <p slot="legend-caption">TASKS DONE</p>

... produces following result. The slots are marked corresponding:

slot example


The plugin was tested in all major modern mobile and desktop browsers. It should also work properly in older browsers. In old browsers issues can arise by animations since they are implemented using CSS custom properties. Basic SVG renders even in IE 11.
