Angular use jQuery plugin with object in external controller

Question

I am new to Angular and I wanted to use the jQuery plugin (d3pie.js). I was looking for my need, and I found some examples explaining that I should create a directive and put in my parameters (and to be sincere, this is a bit confusing for a newbie like me).

My problem is that I did not find how to use a plugin that requires an object as an argument, knowing that this object is in another controller?

Here is an example of using bars, a controller that processes your data and a directive with D3. All of this was found at this link, but I changed it a bit for a better angular code style. http://odiseo.net/angularjs/proper-use-of-d3-js-with-angular-directives .

• All your logic and presentation D3 should be contained in the directive
• Use HTML declarative syntax to feed data to your directive instances
• Thus, you can store data in your controller by passing it to your D3 directive by way of two-way data binding

angular.module('myApp', []) .controller('BarsController', function($scope) { $scope.myData = [10,20,30,40,60, 80, 20, 50]; }) //camel cased directive name //in your HTML, this will be named as bars-chart .directive('barsChart', function ($parse) { //explicitly creating a directive definition variable //this may look verbose but is good for clarification purposes //in real life you'd want to simply return the object {...} var directiveDefinitionObject = { //We restrict its use to an element //as usually <bars-chart> is semantically //more understandable restrict: 'E', //this is important, //we don't want to overwrite our directive declaration //in the HTML mark-up replace: false, //our data source would be an array //passed thru chart-data attribute scope: {data: '=chartData'}, link: function (scope, element, attrs) { //in D3, any selection[0] contains the group //selection[0][0] is the DOM node //but we won't need that this time var chart = d3.select(element[0]); //to our original directive markup bars-chart //we add a div with out chart stling and bind each //data entry to the chart chart.append("div").attr("class", "chart") .selectAll('div') .data(scope.data).enter().append("div") .transition().ease("elastic") .style("width", function(d) { return d + "%"; }) .text(function(d) { return d + "%"; }); //a little of magic: setting it width based //on the data value (d) //and text all with a smooth transition } }; return directiveDefinitionObject; }); 

 .chart { background: #eee; padding: 3px; } .chart div { width: 0; transition: all 1s ease-out; -moz-transition: all 1s ease-out; -webkit-transition: all 1s ease-out; } .chart div { font: 10px sans-serif; background-color: steelblue; text-align: right; padding: 3px; margin: 5px; color: white; box-shadow: 2px 2px 2px #666; }
