嘿,我有一个 Highchart 时间序列的例子。在这个例子中,我将所有点作为小数组的数组(每个数组是一对 x 和 y)。我想知道是否可以使用 fillColor 属性为当前格式的特定点着色,如果可以,我该怎么做?
我想突出显示时间序列图中的特定点,我该怎么做?
$(function () {
$.getJSON('https://www.highcharts.com/samples/data/jsonp.php?filename=usdeur.json&callback=?', function (data) {
$('#container').highcharts({
chart: {
zoomType: 'x'
},
title: {
text: 'USD to EUR exchange rate over time'
},
subtitle: {
text: document.ontouchstart === undefined ?
'Click and drag in the plot area to zoom in' : 'Pinch the chart to zoom in'
},
xAxis: {
type: 'datetime'
},
yAxis: {
title: {
text: 'Exchange rate'
}
},
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: 'USD to EUR',
data: data
}]
});
});

你有两种可能,
1) 在点对象中声明颜色
{
x: 0,
y: 10,
color: 'red'
}

2) 通过point.update()设置颜色
chart.series[0].data[0].update({
color: 'red'
});
