英文:
Temperature from JSON to Highcharts
问题
我有以下的代码，我想从JSON文件中实现温度，但是我不知道我在做什么错。
我尝试了不同的JSON文件配置，没有将其分为温度和露点（dew），但仍然一样。这个结果没有答案...
Highcharts.getJSON(
'https://www.pogodakrotoszyn.info/tempdata.json',
function (data->temp) {
Highcharts.chart('container', {
chart: {
zoomType: 'x'
},
title: {
text: '温度',
align: 'left'
},
subtitle: {
text: document.ontouchstart === undefined ?
'单击并拖动绘图区域进行缩放' : '捏图表以放大',
align: 'left'
},
xAxis: {
type: 'datetime'
},
yAxis: {
title: {
text: '温度'
}
},
legend: {
enabled: false
},
plotOptions: {
area: {
fillColor: {
linearGradient: {
x1: 0,
y1: 0,
x2: 0,
y2: 1
},
stops: [
[0, Highcharts.getOptions().colors[0]],
[1, Highcharts.color(Highcharts.getOptions().colors[0]).setOpacity(0).get('rgba')]
]
},
marker: {
radius: 2
},
lineWidth: 1,
states: {
hover: {
lineWidth: 1
}
},
threshold: null
}
},
series: [{
type: 'area',
name: '温度',
data: data->temp;
}]
});
}
);
希望这有帮助。

I have code like below, I want to implement temperature on it from JSON file, however I don't know what I am doing wrong.
I tried different configurations of the JSON file itself, without the division into temperature and dew point (dew), but still the same. This result gives no answer...
Highcharts.getJSON(
'https://www.pogodakrotoszyn.info/tempdata.json',
function (data->temp) {
Highcharts.chart('container', {
chart: {
zoomType: 'x'
},
title: {
text: 'Temperature',
align: 'left'
},
subtitle: {
text: document.ontouchstart === undefined ?
'Click and drag in the plot area to zoom in' : 'Pinch the chart to zoom in',
align: 'left'
},
xAxis: {
type: 'datetime'
},
yAxis: {
title: {
text: 'Temperature'
}
},
legend: {
enabled: false
},
plotOptions: {
area: {
fillColor: {
linearGradient: {
x1: 0,
y1: 0,
x2: 0,
y2: 1
},
stops: [
[0, Highcharts.getOptions().colors[0]],
[1, Highcharts.color(Highcharts.getOptions().colors[0]).setOpacity(0).get('rgba')]
]
},
marker: {
radius: 2
},
lineWidth: 1,
states: {
hover: {
lineWidth: 1
}
},
threshold: null
}
},
series: [{
type: 'area',
name: 'Temperature',
data: data->temp;
}]
});
}
);

问题在于你在JavaScript代码中使用了PHP语法来访问对象的属性。不应该使用 data->temp，而应该像这样使用 data.temp。
Highcharts.getJSON(
'https://www.pogodakrotoszyn.info/tempdata.json',
function (data) {
Highcharts.chart('container', {
...
series: [{
type: 'area',
name: 'Temperature',
data: data.temp
}]
});
}
);

英文:
The problem is that in the JavaScript code you use PHP syntax to access property of the object. Instead of data->temp you should do it like this data.temp.
Highcharts.getJSON(
'https://www.pogodakrotoszyn.info/tempdata.json',
function (data) {
Highcharts.chart('container', {
...
series: [{
type: 'area',
name: 'Temperature',
data: data.temp
}]
});
}
);
