通常,您不能在单个系列中使用具有相同x值的点。你需要使用像这里的分隔系列:http://jsfiddle.net/5pXfM/5/
{
type: 'flags',
data: [{
x: Date.UTC(2011, 2, 10),
title: ' ',
text: 'Do not move'
}],
onSeries: 'dataseries',
shape: 'circlepin',
color: '#5F86B3',
fillColor: 'rgba(50, 255, 50, .75)',
y: -10,
stackDistance: 5
},{
type: 'flags',
data: [{
x: Date.UTC(2011, 2, 10),
title: ' ',
text: 'Do not move'
}],
onSeries: 'dataseries',
shape: 'circlepin',
color: '#5F86B3',
fillColor: 'rgba(50, 255, 50, .75)',
y: -30,
stackDistance: 5
}
