javascript – amCharts with AngularJS

前端之家收集整理的这篇文章主要介绍了javascript – amCharts with AngularJS前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。
我仍然在使用AngularJS进行其他libs的工作,因为与其他libs不同的逻辑.
我需要使用amCharts库可视化数据,但互联网上没有关于这两个错配在一起的事情.

我如何使用angularjs进行这项工作: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
            }],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"
        },count: 5,label: "5 hour"
        },count: 12,label: "12 hours"
        },{
            period: "MAX",label: "MAX"
        }]
    },panelsSettings: {
        usePrefixes: true
    }
});

谢谢.

解决方法

我将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,我们可以编写几个观察者来监听用户操作.

这里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)

演示Fiddle

指示

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>

HTML

<div>     
    <my-elem ></my-elem>    
</div>

JS

var myapp = angular.module('myModule',[]);

myapp.directive('myElem',template: '<div id="chartdiv" style="min-width: 310px; height: 400px; margin: 0 auto"></div>',attrs) {

                var chart = false;

                var initChart = function() {
                  if (chart) chart.destroy();
                  var config = scope.config || {};
                   chart = AmCharts.makeChart("chartdiv",{
