我发现以下融合图表示例描述了竖线的用法： https://jsfiddle.net/fusioncharts/L5dfydco/
FusionCharts.ready(function() {
var revenueChart = new FusionCharts({
type: 'line',
renderAt: 'chart-container',
width: '500',
height: '300',
dataFormat: 'json',
dataSource: {
"chart": {
"theme": "fusion",
"caption": "Visitors to website",
"subCaption": "Last week",
"xAxisName": "Day",
"yAxisName": "Visits",
"showValues": "0"
},
"data": [{
"label": "Mon",
"value": "5123"
}, {
"label": "Tue",
"value": "4233"
}, {
"label": "Wed",
"value": "5507"
}, {
"label": "Thu",
"value": "4110"
}, {
"label": "Fri",
"value": "5529"
}, {
//Setting data as vline data
"vline": "true",
//Adding label
"label": "Weekend Start",
"linePosition": "0.7"
}, {
"label": "Sat",
"value": "5803"
}, {
"label": "Sun",
"value": "6202"
}]
}
});
revenueChart.render();
});
