QChart如何删除QScatterSeries周围的白色边框

// 获取QChart中的所有系列
QList<QAbstractSeries*> seriesList = chart->series();

// 遍历找到目标QScatterSeries对象
for (QAbstractSeries* series : seriesList) {
    if (series->type() == QAbstractSeries::SeriesTypeScatter) {
        QScatterSeries* scatterSeries = qobject_cast<QScatterSeries*>(series);
        if (scatterSeries) {
            // 设置边框颜色为透明色
            scatterSeries->setPen(QPen(Qt::transparent));
        }
    }
}
