【问题描述】:
在 json 数据中使用 value、value_classification 和 timestamp 值 我正在尝试打印为 Highcharts 的可靠标准。
系列数据中的值作为空白值插入。
有什么问题?
{
"name": "Fear and Greed Index",
"data": [
{
"value": "27",
"value_classification": "Fear",
"timestamp": "21-12-2021",
"time_until_update": "-1639979045"
}
],
"metadata": {
"error": null
}
}
使用该值, 我正在努力完成 Highcharts 的实测。
Highcharts 演示 › 实心量规 https://www.highcharts.com/demo/gauge-solid
到目前为止我尝试过的代码如下。
HTML
<div id="container-speed" class="chart-container"></div>
JAVASCRIPT
$(function () {
var processedData = [];
$.getJSON("https://api.alternative.me/fng/?date_format=en", function (json) {
for (i = 1; i > json.length; i++){
processedData.push(json[i].value);
}
var gaugeOptions = {
chart: {
type: 'solidgauge'
},
title: null,
pane: {
center: ['50%', '85%'],
size: '140%',
startAngle: -90,
endAngle: 90,
background: {
backgroundColor:
Highcharts.defaultOptions.legend.backgroundColor || '#EEE',
innerRadius: '60%',
outerRadius: '100%',
shape: 'arc'
}
},
exporting: {
enabled: false
},
tooltip: {
enabled: false
},
// the value axis
yAxis: {
stops: [
[0.1, '#55BF3B'], // green
[0.5, '#DDDF0D'], // yellow
[0.9, '#DF5353'] // red
],
lineWidth: 0,
tickWidth: 0,
minorTickInterval: null,
tickAmount: 2,
title: {
y: -70
},
labels: {
y: 16
}
},
plotOptions: {
solidgauge: {
dataLabels: {
y: 5,
borderWidth: 0,
useHTML: true
}
}
}
};
// The speed gauge
var chartSpeed = Highcharts.chart('container-speed', Highcharts.merge(gaugeOptions, {
yAxis: {
min: 0,
max: 200,
title: {
text: 'test'
}
},
credits: {
enabled: false
},
series: [{
name: 'test',
data: processedData,
dataLabels: {
format:
'<div style="text-align:center">' +
'<span style="font-size:25px">{y}</span><br/>' +
'<span style="font-size:12px;opacity:0.4">km/h</span>' +
'</div>'
}
}]
}));
});
});
