Highcharts 系列标签相互重叠（重叠）

标签一个接一个（重叠） 是否有正确排列它们的选项？（我的真实数据是动态的，序列数也是动态的）

例如：

---

}))

您可以使用像这里这样的小解决方法

function StaggerDataLabels(series) {
    sc = series.length;
    if (sc < 2) return;

    for (s = 1; s < sc; s++) {
        var s1 = series[s - 1].points,
            s2 = series[s].points,
            l = s1.length,
            diff, h;

        for (i = 0; i < l; i++) {
            if (s1[i].dataLabel && s2[i].dataLabel) {
                diff = s1[i].dataLabel.y - s2[i].dataLabel.y;
                h = s1[i].dataLabel.height + 2;

                if (isLabelOnLabel(s1[i].dataLabel, s2[i].dataLabel)) {
                    if (diff < 0) s1[i].dataLabel.translate(s1[i].dataLabel.translateX, s1[i].dataLabel.translateY - (h + diff));
                    else s2[i].dataLabel.translate(s2[i].dataLabel.translateX, s2[i].dataLabel.translateY - (h - diff));
                }
            }
        }
    }
}

//compares two datalabels and returns true if they overlap


function isLabelOnLabel(a, b) {
    var al = a.x - (a.width / 2);
    var ar = a.x + (a.width / 2);
    var bl = b.x - (b.width / 2);
    var br = b.x + (b.width / 2);

    var at = a.y;
    var ab = a.y + a.height;
    var bt = b.y;
    var bb = b.y + b.height;

    if (bl > ar || br < al) {
        return false;
    } //overlap not possible
    if (bt > ab || bb < at) {
        return false;
    } //overlap not possible
    if (bl > al && bl < ar) {
        return true;
    }
    if (br > al && br < ar) {
        return true;
    }

    if (bt > at && bt < ab) {
        return true;
    }
    if (bb > at && bb < ab) {
        return true;
    }

    return false;
}

函数数据标签（系列）{
sc=系列长度；
如果（sc<2）返回；
对于（s=1；sar | brab | | bbal&&blal&&brat&&btat&&bb

function StaggerDataLabels(series) {
    sc = series.length;
    if (sc < 2) return;

    for (s = 1; s < sc; s++) {
        var s1 = series[s - 1].points,
            s2 = series[s].points,
            l = s1.length,
            diff, h;

            if (s1[i].dataLabel && s2[i].dataLabel) {
                diff = s1[i].dataLabel.y - s2[i].dataLabel.y;
                h = s1[i].dataLabel.height + 2;

                if (isLabelOnLabel(s1[i].dataLabel, s2[i].dataLabel)) {
                    if (diff < 0) s1[i].dataLabel.translate(s1[i].dataLabel.translateX, s1[i].dataLabel.translateY - (h + diff));
                    else s2[i].dataLabel.translate(s2[i].dataLabel.translateX, s2[i].dataLabel.translateY - (h - diff));
                }
            }
        }
    }
