An angular JS directive for meter/speedometer gauge visualization with real time update.

##Demo https://amitgen414.github.io/angular-metergauge

• D3.js v4.2.2
• AngularJS v1.0.1+

You will need to include angular JS and 'D3 JS' in your project to make the directive work

<script src="//ajax.googleapis.com/ajax/libs/angularjs/1.5.8/angular.min.js"></script>
<script src="https://d3js.org/d3.v4.min.js"></script>

Include angular-metergauge module script with above incuded scripts script on your page. You can copy the angular-metergauge.min.js from build folder of repo and add it in your script folder

<script src="./script/angular-metergauge.min.js"></script>

Add angular-metergauge to your app module's dependency.

angular.module('myApp', ['meterGauge']);

$ npm install angular-metergauge 

##Options

We can configure the angular-metergauge for Size, colour,value fonts and other available options. we have to add a variable in scope of the controller and pass it to the config option of directive. Here is an example of classic theme configuration.

angular.module('myApp').controller('myAppController',['$scope', function($scope){
    $scope.classic = {
            gaugeRadius: 140,
            minVal: 0,
            maxVal: 1000,
            needleVal: Math.round(700),
            tickSpaceMinVal: 10,
            tickSpaceMajVal: 100,
            divID: "gaugeBox",
            gaugeUnits: "Kmh",
            tickColMaj:'#656D78',
            tickColMin:'#656D78',
            outerEdgeCol:'#CCD1D9',
            pivotCol:'#434A54',
            innerCol:'#E6E9ED',
            unitsLabelCol:'#656D78',
            tickLabelCol:'#656D78',
            needleCol:'#434A54',
            defaultFonts:''
        }

}]);
 

angular-metergauge is an element directive. you will just have to add the directive in you html view and attach the config variable through scope.

<!--meter gauge with classic as config variable -->
 <meter-gauge gaugeconfig="classic"></meter-gauge>
</div>

##Dynamically Change value For real time update of the metergauge value, configuration's needleVal parameter can be changed in the contoller. Updated value will be immediately reflected if the gauge. In the example give below, after every two seconds, metergauge's value will change.

 $interval(function(){
            $scope.classic.needleVal =Math.round( Math.random()*1000)
  },2000);

##Customization If you want to customize the app according to your needs, here is what should be done.

1. Clone the respository in your local workspace.
2. Install Ruby and Compass in your system as it required for compiling your sass files.
3. Install the npm dependencies.

$ npm install

4. Install bower dependencies.

$ bower install

5. Start the with the dev environment. it will build the project and launch it in the browser with real time code change update.

$ npm run serve 

6. After you are done with your changes , you can run build command

  $ npm run build 

you will have the script as well as a demo website ready.
