我使用Highchart来显示MySQL数据库中的数据。
它可以正确显示图表中的数据。但时间显示为一年。像这样：Full data
但是当我想只查看最后一个数据时，它会显示正确的时间格式（毫秒：＆％;％H：％M：％S＆＃39;）但行和数据消失{{3 }}
这是我的图表：
chart = new Highcharts.stockChart({
chart: {
renderTo : 'container',
type: 'spline',
events: {
load: function () {
this.setTitle(null, {
text: 'Built chart in ' + (new Date() - start) + 'ms'
});
}
}
},
xAxis: {
type: 'datetime',
dateTimeLabelFormats: { // don't display the dummy year
second: '%H:%M:%S'
},
title: {
text: 'Date'
}
},
yAxis: {
opposite: false,
title: {
text: 'Temperature (°C)'
}
},
subtitle: {
text: 'Built chart in ...' // dummy text to reserve space for dynamic subtitle
},
series: [{
name: 'Temperature',
data: (function () {
// generate an array of random data
var data = [];
for (var i = 0; i <= NbRow; i ++) {
data.push([
date_array[i],
temp_array[i]
]);
}
return data;
}()),
marker: {
enabled: true,
radius: 2
},
//pointStart: date_array[0],
//pointInterval: 30000,
tooltip: {
valueDecimals: 2,
valueSuffix: '°C'
}
}]
});
}）; }
temp_array是我的温度数组 date_array是UNIX milisecond格式的本地日期。
我尝试更改dateLabelFormat或添加rangeSelector。但没有任何改变。
编辑：这是我的完整MYSQL表。
