如何用AngularJS整合FLOT？ [英] How to Integrate Flot with AngularJS?

问题描述

我新的角度和海军报，但我用jQuery和Javascript经验。我有点困惑如何去绑定FLOT图表角的数据模型，因为FLOT是一个jQuery插件。我四处搜寻，但一直没能找到一个例子。

I am new to Angular and Flot, but am experienced with Jquery and Javascript. I am a bit confused about how to go about binding a Flot chart to Angular data models, since Flot is a JQuery plugin. I've searched around, but haven't been able to find an example.

我也很乐意使用highcharts，谷歌图表，或其他任何图表的解决方案。

I would also be happy to use highcharts, google-charts, or any other charting solution.

推荐答案

由于图表涉及重DOM操作，指令是要走的路。

Since charting involves heavy DOM manipulation, directives are the way to go.

的数据可以保存在控制器

Data can be kept in the Controller

App.controller('Ctrl', function($scope) {
    $scope.data = [[[0, 1], [1, 5], [2, 2]]];
});

你还可以从

 <chart ng-model='data'></chart>

这角度可通过指令编译

which angular can compile through a directive

App.directive('chart', function() {
    return {
        restrict: 'E',
        link: function(scope, elem, attrs) {
            var data = scope[attrs.ngModel];
            $.plot(elem, data, {});
            elem.show();
        }
    };
});

例这里。

这过程是修改DOM的大部分插件相似。

This process is similar for most plugins that modify the DOM.

此外，您还可以观看在图表的底层数据的变化和重绘，所以这种方式可以通过从控制器$ http服务获取数据，并自动更新视图。这可以通过在指令中定义对象修改链接功能来实现

Also, you can watch for changes in the chart's underlying data and redraw it, so this way you can grab data through the $http service from your controller and update the view automatically. This can be achieved by modifying the linking function in the directive definition object

   var chart = null,
       opts  = { };

    scope.$watch(attrs.ngModel, function(v){
        if(!chart){
            chart = $.plot(elem, v , opts);
            elem.show();
        }else{
            chart.setData(v);
            chart.setupGrid();
            chart.draw();
        }
    });

注意指令中海军报的API的使用来实现我们想要的。

Notice the usage of Flot's API within the directive to achieve what we want.
