到目前为止，我已经通过 PHPExcel 成功地将数据从 Mysql 导出到 Excel 中，制作了我的表格，格式化了，一切都很好。
然而，到目前为止，任何从上述表格制作图表的尝试都失败了。不仅，在谷歌搜索结束几天后，我还没有找到一个关于如何从 MySQL 填充图形值的简单示例/教程。
这一切都归结为：
Taken from https://github.com/affinitybridge/phpexcel/blob/master/Tests/33chartcreate-pie.php
/** PHPExcel */
include 'PHPExcel.php';
$objPHPExcel = new PHPExcel();
$objWorksheet = $objPHPExcel->getActiveSheet();
$objWorksheet->fromArray(
array(
array('', 2010, 2011, 2012),
array('Q1', 12, 15, 21),
array('Q2', 56, 73, 86),
array('Q3', 52, 61, 69),
array('Q4', 30, 32, 0),
)
);
我到底是如何从 a) Mysql 或 b) excel 填充 $objWorksheet->fromArray 的。
如果是 SQL，我需要对数据库中的所有表运行此查询。
$sql = "SELECT Functional_Area, Passed__Status, Blocked__Status, Failed__StatusFROM $tbl_name WHERE 1;
上下文：我有几个功能区域，每个功能区域在通过/失败/阻止中都有不同的值。我需要每个功能区域的 1 个图表。每个表平均有 14 个功能区域。
然后我会为每个功能区域构建一个饼图（或条形图，我不挑剔）。
选项 2) Excel
由于我已经在 excel 中说过数据，因此我需要从以下位置填充数据：
同样，每行 1 个图表（第 5 行（FA = EPG）将是 1 个图表，第 6 行（FA = VOD）将是另一个图表，等等...）。
这将不得不为每个工作表重复...
到目前为止，我的尝试如下，这为每个工作表（这很好）生成了一个图表，但是它是空的（不好）。
