I am trying to create a lollipop chart where some values are negative, and some are positive, either side of zero, like this:
However the chart seemingly only allows the marker to be on the "high" end of the chart. Is there a way to control which end has the marker ?
I'm using these chart options:
chartOptions: {
chart: {
type: 'dumbbell',
inverted: true
},
title: {
text: 'lollipop chart'
},
xAxis: {
type: 'category'
},
yAxis: {
title: {
text: 'value'
}
},
series: [{
name: 'value',
data: [{
name: 'a',
low:0,
high:13,
}, {
name: 'b',
low:0,
high:26,
},{
name: 'c',
low:-43,
high:0
},{
name: 'd',
low:-83,
high:0
},{
name: 'e',
low:0,
high:113
}]
}]
}
The series which should be used in this case is a lollipop, but it seems that the array of objects configuration doesn't work. I reported it on the Highcharts Github issue channel, where you can follow this thread: https://github.com/highcharts/highcharts/issues/13202
As a solution in the dumbell series I suggest to find those graphics in the render callback and hide them.
Demo: https://jsfiddle.net/BlackLabel/3o7acsbt/
events: {
render() {
let chart = this;
chart.series[0].points.forEach(p => {
if (p.low >= 0){
p.lowerGraphic.hide()
} else {
p.upperGraphic.hide()
}
})
}
}

EDIT
Under the GitHub link, the workaround showed up. Please check it, maybe will be fit better to your requirement.
