我仍然在与AngularJS合作开发其他库,因为它与其他库有不同的逻辑.我需要使用amCharts Stock可视化数据,但是互联网上没有任何关于这两个人在一起的事情.
我如何使用angularjs来完成这项工作: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
}],
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,我们可以写几个观察者来听取用户的行为.
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)
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',
function () {
return {

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