是否删除折线图图例符号上的删除线

Question

我正在为折线图上的高线图使用预定义的符号，并且希望只显示符号。我不希望线路也显示在那里。我看到气泡图是可能的，但当我将图表类型从气泡图更改为线条时，会出现删除线：https://jsfiddle.net/gh/get/library/pure/highcharts/highcharts/tree/master/samples/highcharts/plotoptions/bubble-symbol/.有没有想过我该如何应对？提前感谢！

Answer 1

我认为可以使用散点级数类型来实现它。

演示：https://jsfiddle.net/BlackLabel/8gpnx90v/

chart: {
type: 'scatter'
},

API：https://www.highcharts.com/docs/chart-and-series-types/scatter-chart

Answer 2

答案有点晚，但如果将symbolWidth设置为与符号半径相同的值，则会隐藏图例中的行：

legend: {
layout: 'horizontal',
align: 'center',
verticalAlign: 'bottom',
symbolWidth: 6
},  
plotOptions: {
line: {
marker: {
symbol: 'circle',
radius: 6
}
}
},

Answer 3

legend: {
useHTML: true,
enabled: true,
itemStyle: {
font: '9pt Helvetica, Arial, sans-serif',
activecolor: '#CCC',
'font-weight': 'bold',
'text-decoration': 'none'          /** <---  **/
}
}
