如何用PhpSpreadsheet设置组合图表的次坐标轴和X轴坐标间隔？

<code class="php">$chart = new \PhpOffice\PhpSpreadsheet\Chart\Chart();</code>

<code class="php">$dataSeriesValues = [
    new \PhpOffice\PhpSpreadsheet\Chart\DataSeriesValues('Number', 'Worksheet!$A$1:$A$5'), // 主坐标轴数据
    new \PhpOffice\PhpSpreadsheet\Chart\DataSeriesValues('Percentage', 'Worksheet!$B$1:$B$5') // 次坐标轴数据
];

$xAxisTickValues = [
    new \PhpOffice\PhpSpreadsheet\Chart\DataSeriesValues('String', 'Worksheet!$C$1:$C$5') // X轴分类数据
];

$series = new \PhpOffice\PhpSpreadsheet\Chart\Series(
    $dataSeriesValues,
    $xAxisTickValues
);

$series->setPlotDirection(\PhpOffice\PhpSpreadsheet\Chart\Series::PLOT_DIRECTION_HORIZONTAL); // 指定次坐标轴
$chart->addSeries($series);


$series = new \PhpOffice\PhpSpreadsheet\Chart\Series(
    new \PhpOffice\PhpSpreadsheet\Chart\DataSeriesValues('Number', 'Worksheet!$A$1:$A$5') // 主坐标轴数据
);

$series->setPlotDirection(\PhpOffice\PhpSpreadsheet\Chart\Series::PLOT_DIRECTION_VERTICAL); // 指定主坐标轴
$chart->addSeries($series);</code>

<code class="php">$layoutSecondaryAxes = new \PhpOffice\PhpSpreadsheet\Chart\Layout\Layout();
$layoutSecondaryAxes->setShowAxis(true);

$yAxisSecondary = new \PhpOffice\PhpSpreadsheet\Chart\Axis();
$yAxisSecondary->setLayout($layoutSecondaryAxes);

$chart->addAxis($yAxisSecondary, \PhpOffice\PhpSpreadsheet\Chart\Axis::VERTICAL, $layoutSecondaryAxes); // 添加次坐标轴</code>

<code class="php">$layoutXAxis = new \PhpOffice\PhpSpreadsheet\Chart\Layout\Layout();
$layoutXAxis->setTickValFrequency(1); // 设置X轴坐标间隔为1

$xAxis = new \PhpOffice\PhpSpreadsheet\Chart\Axis();
$xAxis->setLayout($layoutXAxis);

$chart->addAxis($xAxis, \PhpOffice\PhpSpreadsheet\Chart\Axis::HORIZONTAL); // 添加X轴</code>

<code class="php">$worksheet->addChart($chart);</code>
