NOTE: In angular-gauge 2.x, some breaking changes have been introduced. If you are upgrading from v1.x.x
version to v2.x.x
then checkout the Upgrade Guide first.
npm install angularjs-gauge
bower install angularjs-gauge
git clone https://github.com/ashish-chopra/angular-gauge.git
Copy the files from dist/
manually into your project folder.Then, add the script to your code (after adding the dependency of Angular 1.5) and resolving the paths as given below:
<head>
...
<head>
<body>
...
</body>
<script src="vendor/angular/angular.min.js"></script>
<script src="vendor/angularjs-gauge/dist/angularjs-gauge.min.js"></script>
Add as dependency in your module
angular.module('yourApp', ['angularjs-gauge']);
Use it in your HTML markup like this
<ng-gauge size="200" type="full" thick="5" min="0" max="120" value="68.2" cap="round" label="Speed" foreground-color="#ffcc66" background-color="rgba(255,255,255, 0.4)" append="mph"></ng-gauge>

angular-gauge ships with a provider to globally set config options for all gauge instances used in the application during angular config phase. You can specify ngGaugeProvider
dependency during config
phase. It supports a single API to set config options:
ngGaugeProvider.setOptions(customOptions);
Here, customOptions
is an object {}
where keys are the configOptions name (in camelCase notation), mentioned in above section. For example, let see how to set size
, cap
, thick
, foreground-color
and background-color
options globally using provider as shown below:
angular
.module('myApp', ['angularjs-gauge'])
.config(configApp);
configApp.$inject = ['ngGaugeProvider'];
function configApp(ngGaugeProvider) {
// setting the default parameters for
// gauge instances globally.
ngGaugeProvider.setOptions({
size: 250,
cap: 'round',
thick: 15,
foregroundColor: "#ff8645", // note the camelCase notation for parameter name
backgroundColor: "#e4e4e4"
});
}
The examples section is redesigned as a playground where you can play with Gauge by tuning its different parameters. And, you can see the result live on-screen. It is good start to get familiar with Gauge.
If you are upgrading from angular-gauge 1.x version to any version in 2.x family, then make sure to read the release notes of the chosen version on the Releases section.
Following are the breaking changes introduced in 2.x.x onwards:
used
