我的数据看起来像JSON格式。我有两个具有相同时间线的数据系列。当我试图用高品质绘制它们时,我所有的时间戳都显示在20世纪70年代。任何人都可以指出我的JSON格式会出现什么问题吗?
我没有使用的原因 - pointStart和pointInterval:是因为有时pointIntervals可能是不规则的,因此需要发送日期。
{
"chart_data": {
"dates": [
1406876400000,
1406876700000,
1406877000000,
1406877300000,
1406877600000,
1406877900000,
1406878200000,
1406878500000,
1406878800000
],
"values": [
{
"data": [
54,
50,
62,
65,
65,
55,
51,
53,
57
]
},
{
"data": [
84,
70,
80,
78,
77,
84,
73,
83,
77
]
}
]
}
}
我的Javascript方法显示此数据如下。
<script type="text/javascript">
$(document).ready(function() {
var chartOptions = {
chart: {
renderTo: 'chart_panel',
type: 'line',
zoomType: 'x'
},
legend: {
layout: 'vertical',
align: 'right',
verticalAlign: 'middle',
borderWidth: 0
},
title: {text: 'Temperature & Humidity' },
subtitle: {text: 'My-Text' },
xAxis: {
type: 'datetime',
dateTimeLabelFormats: {
month: '%e. %b',
day: '%b %e',
hour: '%b %e',
year: '%b'
}
},
yAxis: {
min: 0,
title: {
text: 'Temperature (°F)/Humidity (%)'
},
plotLines: [{
value: 0,
width: 1,
color: '#808080'
}]
},
series: [{}],
rangeSelector : {
inputEnabled: true,
selected: '0'
},
};
var chartDataUrl = '{% url "chart_data_json" object.id %}';
function loadChart() {
$.getJSON(chartDataUrl,
function(data) {
var seriesOptions = [];
var obj1 = {};
var obj2 = {};
avgByDayOptions.xAxis.categories = data['chart_data']['dates'];
obj1.name = "Temperature";
obj1.data = data['chart_data']['values'][0]['data'];
obj2.data = data['chart_data']['values'][1]['data'];
obj2.name = "Humidity";
seriesOptions[0] = obj1;
seriesOptions[1] = obj2;
chartOptions.series = seriesOptions;
var chart = new Highcharts.StockChart( chartOptions,
function(chart){
// apply the date pickers
setTimeout(function(){
$('input.highcharts-range-selector', $('#'+chart.options.chart.renderTo))
.datepicker()
},0)
}
);
Highcharts.setOptions({ global: { useUTC: false } });
});
}
loadChart();
});
答案 0 :(得分:0)
一旦我按照以下格式传递数据,一切都按预期开始工作,这可能很糟糕。如果有人遇到类似的问题,只是回复我自己的问题?
