我试图让这个图表有多个Y轴,所有这些都有不同的值和滴答间隔。像信号强度的范围为0%-100%,温度0F-100F和主电源为0V到25V,但似乎无法弄清楚。这里是我的jFiddle: http://jsfiddle.net/0k5k8ygz/Highcharts |制作多个y轴刻度
代码:
function createChart() {
Highcharts.stockChart('container', {
rangeSelector: {
selected: 4
},
yAxis: [{ // Primary yAxis
labels: {
format: '{value}°F',
style: {
color: Highcharts.getOptions().colors[2]
}
},
title: {
text: 'Temperature',
style: {
color: Highcharts.getOptions().colors[2]
}
},
opposite: true
}, { // Secondary yAxis
gridLineWidth: 0,
title: {
text: 'Main Power',
style: {
color: Highcharts.getOptions().colors[0]
}
},
labels: {
format: '{value} volts',
style: {
color: Highcharts.getOptions().colors[0]
}
}
}, { // Tertiary yAxis
gridLineWidth: 0,
title: {
text: 'Signal Strength',
style: {
color: Highcharts.getOptions().colors[1]
}
},
labels: {
format: '{value} %',
style: {
color: Highcharts.getOptions().colors[1]
}
},
opposite: true
}],
plotOptions: {
series: {
compare: 'percent',
showInNavigator: true
}
},
tooltip: {
pointFormat: '<span style="color:{series.color}">{series.name}</span>: <b>{point.y}</b> ({point.change}%)<br/>',
valueDecimals: 2,
split: true
},
series: seriesOptions
});
$.each(names, function (i, name) {
$.getJSON('https://www.highcharts.com/samples/data/jsonp.php?filename=' + name.toLowerCase() + '-c.json&callback=?', function (data) {
seriesOptions[i] = {
name: name,
data: data
};
// As we're loading the data asynchronously, we don't know what order it will arrive. So
// we keep a counter and create the chart when all the data is loaded.
seriesCounter += 1;
if (seriesCounter === names.length) {
createChart();
}
});
});
那么什么是实际问题(具体)? – jlbriggs
对不起,我不知道如何将数值添加到所有3个Y轴的比例。在图表的右侧,主电源和信号强度均为空白。我将如何去让他们有数值?主要功率范围为0至24,信号强度范围为0%至100% –
