我有一些来自elasticsearch的数据,它有任务的开始和时间.特定代理程序任务的结束时间,需要在图表上水平绘制,指示该特定任务的开始和结束时间.我尝试使用columnrange图表类型但是因为我无法进入范围选择器see here an example.
然后我再次尝试了this,我能够使它工作,但需要帮助在高级图中绘制Elasticsearch数据.
另一个问题是我从服务器获得的日期是人类可读的dateformat(检查start_time和end_time),EST时区,需要转换为highcharts可以使用的格式.请帮忙.
我的高级指令
angular.module('myApp').directive('operationalhighstackstock', function() {
return {
restrict : 'E',
scope : true,
link : function postLink(scope, element, attrs) {
scope.$watch('operationHighChartsData', function(values){
new Highcharts.StockChart(values);
});
}
};
});
我的模板
<div style="width: 100%;">
<operationalhighstackstock></operationalhighstackstock>
<div id="container" style="width: 100%; height: 500px;"></div>
</div>
我的控制器
angular.module('myApp').controller('OperationReportChartController', function($scope, $filter, $location, $transition, MyService, $timeout) {
$scope.init = function() {
$scope.isOperationalReport = true;
$scope.initOperationalReport();
}
$scope.initOperationalReport = function() {
$scope.loading = true;
$scope.isChartDataAvailable = true;
$scope.operationReportDefaultQuery = operationReportDefaultQuery;
$scope.operationHighChartsData = {
chart : {
renderTo : 'container',
alignTicks : false
}
};
$scope.operationalReportDefaultServiceRequests();
}
$scope.serviceRequests = function() {
//Common service requests if any
}
$scope.operationalReportDefaultServiceRequests = function() {
$scope.isOperationalReport = true;
MyService.getOperationalReportChartData($scope.operationReportDefaultQuery).then(function(result) {
renderOperationalHighCharts(result);
});
}
function renderOperationalHighCharts(result) {
//var xAxisCategories = ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec']
//var series = getOperationReportChartSeriesData(result);
var chart_options = {
chart: {
renderTo: 'container'
},
xAxis: {
type: 'datetime'
},
yAxis: {
tickInterval: 1,
labels: {
formatter: function() {
if (tasks[this.value]) {
return tasks[this.value].name;
}
}
},
startOnTick: false,
endOnTick: false,
minPadding: 1,
maxPadding: 1
},
legend: {
enabled: false
},
plotOptions: {
line: {
lineWidth: 9,
marker: {
enabled: false
},
dataLabels: {
enabled: true,
align: 'left',
formatter: function() {
return this.point.options && this.point.options.label;
}
}
}
},
series: series
};
$scope.operationHighChartsData = chart_options;
}
$scope.init();
});
Highcharts需要消耗部分完整的数据,显示特定代理的任务开始和结束时间.

更新
抱歉所有的困惑.为了使json响应变得简单(如上所述),函数(getOperationReportChartSeriesData())将以这样的方式准备数据：Highcharts将显示单个任务,并且它在水平条中运行历史记录,其中x轴是日期时间(包括小时和分钟)和y轴是任务.与下面提供的屏幕截图类似.
以下是预期结果的屏幕截图.

更新了jsfiddle链接here
但在此我还需要StockChart navigation & range selectors.
@Pawel Fus：非常感谢与我合作.对于遇到类似问题的人来说,这是最终结果.
解决方法:
我对你的要求有点困惑(仍然).
Highcharts,需要时间戳(以毫秒为单位)进行渲染.因此,您需要预处理日期,例如：new Date(“2014-11-20T11：03：55.000-08：00”).getTime()以获取UTC时间戳.现在,当您有UTC时间时,您可以使用上面建议的moment.js来呈现特定时区的数据.
要在Highcharts中使用moment.js,可以通过以下方式扩展getTimezoneOffset选项(实验)：
Highcharts.setOptions({
global: {
/**
* Use moment-timezone.js to return the timezone offset for individual
* timestamps, used in the X axis labels and the tooltip header.
*/
getTimezoneOffset: function (timestamp) {
var zone = 'Europe/Oslo',
timezoneOffset = moment.tz.zone(zone).parse(timestamp);
return timezoneOffset;
}
}
});
现场例子：http://jsfiddle.net/k96t1dy7/3/
注意：你的第二个弹药不起作用..
注2：以上测试用例使用的是Highfrts的github版本.它是Highcharts 4.1的候选版本.
