Angular/D3.js Chart Directives

A Demo can be found here: http://chaosmail.at/2013/angular-dchart/ Features

• Angular Directives for different Chart types
• Data Binding
• Fully customizable Options (Axes, Datasets) via Html tags
• Autorescaling
• Plot datasets or functions
• Easy Extensibility (Checkout the source of the different Chart types, generally they only need a drawData() function)

Controller

var app = angular.module('dchart.demo', ['dchart.line', 'dchart.histo', 'dchart.scatter']);

app.controller("MainCtrl", ['$scope', function($scope) {

$scope.fn = {};
$scope.fn.sin = function(x) { return Math.sin(x*Math.PI/180); };
$scope.fn.cos = function(x) { return Math.cos(x*Math.PI/180); };
$scope.fn.tan = function(x) { return Math.tan(x*Math.PI/180); };

$scope.fn.rnd = function(x) { return Math.random()*100; };

$scope.histoDataSet1 = [
    {label:"monday",y:$scope.fn.rnd()},
    {label:"tuesday",y:$scope.fn.rnd()},
    {label:"wednesday",y:$scope.fn.rnd()},
    {label:"thursday",y:$scope.fn.rnd()},
    {label:"friday",y:$scope.fn.rnd()},
    {label:"saturday",y:$scope.fn.rnd()},
    {label:"sunday",y:$scope.fn.rnd()}

$scope.histoDataSet2 = [
    {label:"06:30-07:00",y:$scope.fn.rnd()},

    {label:">08:00",y:$scope.fn.rnd()}
];

$scope.createScatterDataSet = function(max,m) {
    var data = [];

    for(var i=0; i<max; i++) {
        data.push({x:Math.random()*m,y:Math.random()*m,w:Math.random()});
    }

    return data;
};

$scope.scatterDataSet1 = $scope.createScatterDataSet(100,100);
$scope.scatterDataSet2 = $scope.createScatterDataSet(100,100);
$scope.scatterDataSet3 = $scope.createScatterDataSet(50,50);
$scope.scatterDataSet4 = $scope.createScatterDataSet(50,50);
}]);
