amCharts with AngularJS
提问by Hyman
I'm still strugling making work other libs with AngularJS because of it's differtent logic from other libs. I need to visualize data with amCharts Stock, but there is nothing on the internet about these two wroking together.
我仍在努力使用 AngularJS 制作其他库，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任何内容。
How can i make this work with angularjs: http://jsfiddle.net/922JW/
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: {

}
},
{

I would create some basic directive (isolate scope) that receives chart settings and use as template:
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>
In addition we can write several watchers to listen on user actions.
此外，我们可以编写几个观察者来监听用户的动作。
Here is working example How to use it:

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
}
}) ;
The usage:
用法：
<my-elem config="chartConfig"> </my-elem>

回答by Giacomo
I fount that the solution provided wasn't working for me.
我发现提供的解决方案对我不起作用。
In particular, the chart was not showing if the id in the template wasn't hardcoded.
特别是，如果模板中的 id 不是硬编码的，图表就不会显示。
It seemed like a problem with the AmCharts.makeChart()function that was't able to find the chardiv_idin the DOM.
似乎AmCharts.makeChart()无法chardiv_id在 DOM 中找到 的函数有问题。
I found that putting the initChart()function inside a scope.$watch('element')(after attaching elementto the scope in the linking function) was the right solution for me.
我发现将initChart()函数放在 a 中scope.$watch('element')（在element链接函数中附加到作用域之后）对我来说是正确的解决方案。
I think this is because after the elementis created (so after the watch is called) is present and visiblein the DOM, so the AmChart function can see it and render the chart correctly.
我认为这是因为在element创建之后（因此在调用 watch 之后）在 DOM 中存在并且可见，因此 AmChart 函数可以看到它并正确呈现图表。
Hope this helped someone!
