phpexcel - PHP Excel，条形图和折线图的可能性？

Question

是否可以使用 PHPExcel 创建折线图和条形图？比如下面这个。

如果不是，是否可以使图形背景透明，以便我可以将两个图形合并在一起？

Answer 1

我不得不对 PHPExcel 代码进行一些小调整以使其正常工作，只需将其推送到 github；连同 /Examples 中的 33chartcreate-composite-chart.php。

$objPHPExcel = new PHPExcel();
$objWorksheet = $objPHPExcel->getActiveSheet();
$objWorksheet->fromArray(
    array(
        array('',       'Rainfall (mm)',    'Temperature (°F)', 'Humidity (%)'),
        array('Jan',        78,                 52,                 61),
        array('Feb',        64,                 54,                 62),
        array('Mar',        62,                 57,                 63),
