Options

Options are provided as attributes ‘data-circle-option’:

<div id="circle-1" data-circle-dialWidth=10 data-circle-skin="white"></div>

or in the “Circlebar()” call :

$("#circle-1").Circlebar({
    maxValue : 20,
    fontSize : "14px",
    triggerPercentage : true
});

• Note : The inline data attributes will overwrite the properties specified in the Circlebar() call .

The following options are supported :

• Note : value and maxValue options are common for both (timer and progressbar) but vary slightly in essence to both.

Behaviors :

• startValue : starting time for timer or initial value of progressbar | default = 0 | integer
• maxValue : the max time for timer to display or the value till which circlebar progresses | default = 60 | integer
• counter : the time in which timer increase by 1s | default = 1000 | integer (1000 == 1sec)
• triggerPercentage : should the circles styling alters according to progress level | default = false | boolean
• type : type of circlebar can be timer, progress or manual | default = “timer”

UI :

• dialWidth : the thickness of the circular ring | default = 5 | integer
• fontSize : the font size of the text in center of circle | default = “20px” | string with unit also ( units can be px, em, rm, % etc.)
• fontColor : the font color of the text in center of circle | default = “rgb(135, 206, 235)” | string (unit can be HEX, rgb, rgba, hsla, hsv, etc.)
• skin : the name of the custom skin to include | default = “ “ | string
• size : the size of the whole circle bar | default = “150px” | string with unit also ( units can be px, % etc.)

Avaliable skins

All Skins are located in the dist/skins folder. Here are the ones currently avaliable:

• Blue
• Cobalt
• Fire
• Matte Black
• Purple
• Simple
• White
• Yellow

To use a skin, first include it as a css file.

<link rel="stylesheet" type="text/css" href="path/to/skins/bluecircle.css">

Then, you can set the custom skin name with the skin option when creating your circebar instance.

$("#circle-1").Circlebar({
    skin: "blue"
});

Or, as a data attribute when using a DOM element.

<div id="circle-1" data-circle-skin="blue"></div>

To make your own skin, use one of the included ones and edit the css to your specification.

Example

 <div id="circle-1" data-circle-dialWidth=10 data-circle-skin="white">
    <div class="loader-bg">
      <div class="text">00:00:00</div>
    </div>
</div>
$("#circle-1").Circlebar({
    maxValue : 20,
    fontSize : "14px",
    triggerPercentage : true,
    type: "progress"
});

and

<div class="circlebar" data-circle-startValue=0 data-circle-dialWidth=20 data-circle-size="250px">
    <div class="loader-bg">
        <div class="text">00:00:00</div>
    </div>
</div>

Note that you can put any content inside<div class="text"></div> like text, icons, images, etc.
