$yAxis = new \PHPExcel_Chart_Axis();
$yAxis->setsetAxisOptionsPRoPErties(
    \PHPExcel_Chart_Axis::AXIS_LABELS_NEXT_TO,null,\PHPExcel_Properties::orientation_revERSED
);

$chart = new \PHPExcel_Chart(
    "Chart1",$tITile,$legend,$plotArea,true,'0',//xAxis parameter if you want to reverse the x axis
    $yAxis
);

注意：如果将系列方向设置为列而不是条形

$series = new \PHPExcel_Chart_DataSeries(....);
$series->setPlotDirection(\PHPExcel_Chart_DataSeries::DIRECTION_COL);

轴是反转的,因此您设置为Y轴的选项将应用于X轴和相反的轴.

但是,通过预期工作的其他方法无法实现反转轴：

$chart->getchartAxisY()->setAxisOrientation(\PHPExcel_Properties::ORIENTATION_REVERSED);

要么

$yAxis = new \PHPExcel_Chart_Axis();
$yAxis->setAxisOrientation(\PHPExcel_Properties::ORIENTATION_REVERSED);

$chart = new \PHPExcel_Chart(
    "Chart1",//xAxis parameter if you want to reverse the x axis
    $yAxis
);
