javascript - 带有 AngularJS 的 amCharts

Question

我仍在努力使其他库与 AngularJS 一起工作，因为它与其他库的逻辑不同。我需要使用 amCharts Stock 可视化数据，但互联网上没有关于这两者一起工作的信息。

我怎样才能使它与 angularjs 一起工作:http://jsfiddle.net/922JW/

 var chart = AmCharts.makeChart("chartdiv", {

    type: "stock",
    "theme": "none",
    pathToImages: "http://www.amcharts.com/lib/3/images/",

    categoryAxesSettings: {
        minPeriod: "mm"
    },

    dataSets: [{
        color: "#b0de09",
        fieldMappings: [{
            fromField: "value",
            toField: "value"
        }, {
            fromField: "volume",
            toField: "volume"
        }],

        dataProvider: chartData,
        categoryField: "date"
    }],


    panels: [{
            showCategoryAxis: false,
            title: "Value",
            percentHeight: 70,

            stockGraphs: [{
                id: "g1",
                valueField: "value",
                type: "smoothedLine",
                lineThickness: 2,
                bullet: "round"
            }],


            stockLegend: {
                valueTextRegular: " ",
                markerType: "none"
            }
        },

        {
            title: "Volume",
            percentHeight: 30,
            stockGraphs: [{
                valueField: "volume",
                type: "column",
                cornerRadiusTop: 2,
                fillAlphas: 1
            }],

            stockLegend: {
                valueTextRegular: " ",
                markerType: "none"
            }
        }
    ],

    chartScrollbarSettings: {
        graph: "g1",
        usePeriod: "10mm",
        position: "top"
    },

    chartCursorSettings: {
        valueBalloonsEnabled: true
    },

    periodSelector: {
        position: "top",
        dateFormat: "YYYY-MM-DD JJ:NN",
        inputFieldWidth: 150,
        periods: [{
            period: "hh",
            count: 1,
            label: "1 hour",
            selected: true

        }, {
            period: "hh",
            count: 2,
            label: "2 hours"
        }, {
            period: "hh",
            count: 5,
            label: "5 hour"
        }, {
            period: "hh",
            count: 12,
            label: "12 hours"
        }, {
            period: "MAX",
            label: "MAX"
        }]
    },

    panelsSettings: {
        usePrefixes: true
    }
});

谢谢。

我会创建一些接收图表设置并用作模板的基本指令(隔离范围):

 <div id="container"></div>

此外，我们可以编写多个观察器来监听用户操作。

这是工作示例如何使用它:

(它不是基于您的设置，但您可以使用相同的流程)

myapp.directive('myElem',
   function () {
       return {
           restrict: 'E',
           replace:true,
            scope: {
            config: '='  
           },
           template: '<div id="container" style="min-width: 310px; height: 400px; margin: 0 auto"></div>',
           link: function (scope, element, attrs) {

                var chart = false;

                var initChart = function() {
                  if (chart) chart.destroy();
                  var config = scope.config || {};
                  chart = new Highcharts.Chart(config);


                  if(config.loading) {
                    chart.showLoading();
                  }

                };
                initChart();

        scope.$watch('config.loading', function (loading) {
          if(loading) {
            chart.showLoading();
          } else {
            chart.hideLoading();
          }
        });

       scope.$watch('config.series[0].type', function (type) {        
         chart.series[0].update({type: type});       
        });

        scope.$watch('config.series[0].dataLabels.enabled', function (enableDataLabels) {          
         chart.series[0].update({dataLabels: {enabled: enableDataLabels}});       
        });                
         }//end watch

       }
   }) ;

用法:

 <my-elem config="chartConfig"> </my-elem>
