Binding between Angular.JS and Flot charts library

angular-flot

An Angular directive that wraps Flotcharts.

Installation

This library is provided as a Bower component and NPM module:

• Bower: bower install angular-flot
• NPM: npm install angular-flot

How to Use

First, make sure to add Flotchart to your project, as explained in Flotchart's ReadMe since we don't bundle Flotcharts for you.

Add angular-flot to the list of dependencies in your Angular.JS application:

angular.module('myapp', [
    'ngRoute',
    // ...
    'angular-flot'
]);

In your controller, create two variables to hold the dataset and Flot chart options:

angular.module('myapp').controller('MyController', function ($scope) {
    $scope.myData = [];
    $scope.myChartOptions = {};
});

In your view or template, add the flot directive, making sure to specify both the dataset and options attributes, pointing to the scope variables defined above:

<flot dataset="myData" options="myChartOptions"></flot>

The Flot chart is created in a div element as a child of the flot directive. To select the DOM element using jQuery, just do as follows (you might have to adjust the example based on the contents of your page):

$('flot > div');
