'PHP Spreadsheet'的前10个值是否可能以黄色显示

Question

这是我的代码，它根据值生成简单的条形图。现在，如果值大于10，我想着色。

我认为问题是dataSeriesValue，它仅基于一种类型的数据序列产生一个时间图。有可能使用两次吗？例如，如果值大于10而不是黄色，则小于10为绿色，小于1为红色

use PhpOffice\PhpSpreadsheet\IOFactory;

$spreadsheet = new Spreadsheet();

$worksheet = $spreadsheet->getActiveSheet();

$spreadsheet->getActiveSheet()->getColumnDimension('A')->setWidth(30);
$spreadsheet->getActiveSheet()->getColumnDimension('B')->setWidth(30);

$worksheet->setCellValue('A1','Bazar Name');
$worksheet->setCellValue('B1','Number of Shops');

$worksheet->fromArray([
    [''],
    ['Bazar Name 1', 9],
    ['Bazar Name 2', 16],
    ['Bazar Name 3', 7],

$plotArea = new PlotArea(null, [$series]);

$chart->setTopLeftPosition('A7');
$chart->setBottomRightPosition('H20');

$worksheet->addChart($chart);

$writer = IOFactory::createWriter($spreadsheet, 'Xlsx');
$writer->setIncludeCharts(TRUE);**strong text**
$writer->setPreCalculateFormulas(false);
//$writer->save('test.xlsx');
header('Content-Type: application/vnd.ms-excel');
header('Content-Disposition: attachment; filename="file.xlsx"');
$writer->save("php://output");
