This is a dead simple directive that implements a basic AngularJS directive for stacked bar charts. It was made taking into account a very specific environment:

• Angular 1.3.x
• Globally available d3 object

The code is based on this example.

For now, I'd suggest to use npm and napa to install the module.

Just add <stacked-bars data="{{controller.data}}" options="{{controller.options}}"></stacked-bars>

An hash of params to setup the chart behaviour:

• width (int): the width of the svg element;
• height (int): the height of the svg element;
• margin[Left|Right|Top|Bottom] (int): sets the margin of the chart relatively to the svg element;
• visibleXX (boolean): sets the visibility of the XX axis;
• visibleYY (boolean): sets the visibility of the YY axis;
• stacksColor (array): an array of colors for each stack in the chart;
• stacks (array): an array of values to build the stacks;
• xx (string): a string defining which values should be used in XX axis;

E.g.:

$scope.options = {
  visibleYY: false,
  stacksColor: ['orange', 'yellow'],
  xx: 'x',
  stacks: ['y', 'z']
}

An array of data structures. E.g.:

(...)
$scope.data = [
  {x: 'Foo', y: 5, z: 8},
  {x: 'Bar', y: 7, z: 3}
];
(...)

Controller

angular.module( "app" )
  .controller( "ChartController" ["$scope", function( $scope ) {
    $scope.data = [
      {x: "Foo", y: 5, z: 8},
      {x: "Post B", y: 7, z: 3}
    ];

    $scope.options = {
      visibleYY: false,
      stacksColor: ["orange", "yellow"],
      xx: "x",
      stacks: ["y", "z"]
    };
  }]);

Template

<stacked-bars
  data="{{data}}"
  options="{{options}}">
</stacked-bars>

• Tidy up the code and add tests;
• Make this a proper package;
• Accept CSS classes to style bars, axis and other relevant elements;
• Animate bars drawing;
• ...
