如何确定图表中出现的每个列系列的宽度 [英] how to determine the width of every column series present in the chart- highhcarts
问题描述
我在x轴上添加了stackLabel,添加了格式化程序功能,该功能将截断x轴标签以适合图表大小:
I have stackLabels that I have added in the x- axis, I have added a formatter function that will truncate the x-axis labels in order to fit into the chart size: something like this:

但是随着数据和系列柱形图的宽度发生变化,我也想更改字符串上截断的字符数.目前,我有以下内容:
however as the data and the width of the series column chart changes I would also like to change the truncated number of chars on the string.currently I have this:
stackLabels: {
enabled: true,
verticalAlign: 'bottom',
//y:160,
style: {
fontWeight: 'bold',
color: 'gray'
},
formatter: function () {
let label = this.stack || '';
let truncatedLabel = label.length <= 3
? label : `${label.substring(0, 3)}...`;
return `<span>${truncatedLabel}</span>`;
},
}
以上内容将始终截断字符串,而不管序列列的大小如何.如果有更宽的序列可用,它仍将截断为3.
the above will always truncate the string regardless of the size of the series column.ex if a wider series is available it'll still truncate to 3. like this

相反,我想展示这个 https://jsfiddle.net/f2bv35gy/
Instead I would like to show this https://jsfiddle.net/f2bv35gy/
是否有任何方法可以根据图表点的宽度将子字符串的char号动态传递给字符串?
is there any way to dynamically pass the substring char number to the string based on the chart point width?
推荐答案
尝试使用dataLabels
代替stackLabels
,并使用以下配置:
Try to use the dataLabels
instead the stackLabels
and use the below config:
events: {
render() {
const chart = this;
chart.series.forEach(s => {
s.points.forEach(p => {
if (p.dataLabel && p.dataLabel.width > p.pointWidth || p.dataLabel && p.dataLabel.text.styles.textOverflow) {
let dataLabel = p.dataLabel;
dataLabel.css({
width: p.pointWidth,
textOverflow: 'ellipsis'
})
dataLabel.translate(p.barX - 5, chart.plotHeight)
}
})
})
}
}
