通过x和y绘图线，highcharts将文本添加到生成的象限区域
我有一个散点图来展示来自具有两个维度x和y的服务器的一些负载。
我将定义两条情节线来显示该点是否过载，这就像演示节目（只是一个快速演示，所以我只是复制链接）：
"http://codepen.io/anon/pen/xZprWa"
同时，我还需要证明生成的象限是什么意思，有些标签就像：
但是我无法从api中找到任何方法/选项来实现这一点，有没有简单的方法来做到这一点？喜欢找到位置并给它贴上绝对位置？

您可以定义每个x和y轴的plotLines，然后捕获load事件。在该函数内部，您应该提取线的位置并使用渲染器来打印标签。最后一步是计算到正确的四分之一（通过与plotLines比较并检查标签的宽度 - getBBox - 函数）。
chart: {
events: {
load: function() {
var chart = this,
r = chart.renderer,
each = Highcharts.each,
left = chart.plotLeft,
top = chart.plotTop,
h = chart.plotHeight,
w = chart.plotWidth,
xAxis = chart.xAxis[0],
yAxis = chart.yAxis[0],
labels = ['top-left', 'top-right', 'bottom-left', 'bottom-right'],
labelStyles = {
'font-size': '12px',
'color': 'red'
},
attr = {
zIndex: 10
},
xPlotLine, yPlotLine,bbox, x, y;
chart.label = [];
xPlotLine = xAxis.toPixels(xAxis.plotLinesAndBands[0].options.value);
yPlotLine = yAxis.toPixels(yAxis.plotLinesAndBands[0].options.value);
//render
each(labels, function(label, i) {
chart.label[i] = r.text(label, 0, 0)
.attr(attr)
.css(labelStyles)
.add();
bbox = chart.label[i].getBBox();
console.log(w);
switch(i) {
case 0:
x = ((xPlotLine + left) / 2) - (bbox.width / 2);
y = ((yPlotLine + top) / 2) - (bbox.height / 2);
break;
case 1:
x = left + xPlotLine + ((w - xPlotLine)/2) - (bbox.width / 2);
y = ((yPlotLine + top) / 2) - (bbox.height / 2);
break;
case 2:
x = ((xPlotLine + left) / 2) - (bbox.width / 2);
y = top + yPlotLine + ((h - yPlotLine) / 2) - (bbox.height / 2);
break;
case 3:
x = left + xPlotLine + ((w - xPlotLine)/2) - (bbox.width / 2);
y = top + yPlotLine + ((h - yPlotLine) / 2) - (bbox.height / 2);
break;
}
chart.label[i].attr({
x: x,
y: y
});
});
}
}
},
xAxis: {
plotLines: [{
id: 'ver',
color: '#FF0000',
width: 2,
value: 2
}]
},
yAxis: {
plotLines: [{
id: 'hor',
color: '#FF0000',
width: 2,
value: 100
}]
},

查看Highcharts renderer api了解更多详情。您可以在绘制图表后定义如下所示的回调函数并修改图表。
$(function() {
$('#container').highcharts({
chart: {
type: 'scatter',
zoomType: 'xy'
},
title: {
text: 'Height Versus Weight of 507 Individuals by Gender'
},
subtitle: {
text: 'Source: Heinz 2003'
},
xAxis: {
title: {
enabled: true,
text: 'Height (cm)'
},
threshold: 190,
startOnTick: true,
endOnTick: true,
showLastLabel: true
},
yAxis: {
title: {
text: 'Weight (kg)'
}
},
legend: {
layout: 'vertical',
align: 'center',
verticalAlign: 'bottom',
x: 100,
y: 70,
floating: true,
backgroundColor: (Highcharts.theme && Highcharts.theme.legendBackgroundColor) || '#FFFFFF',
borderWidth: 1
},
plotOptions: {
scatter: {
marker: {
radius: 5,
states: {
hover: {
enabled: true,
lineColor: 'rgb(100,100,100)'
}
}
},
states: {
hover: {
marker: {
enabled: false
}
}
},
tooltip: {
headerFormat: '<b>{series.name}</b><br>',
pointFormat: '{point.x} cm, {point.y} kg'
}
}
},
