我需要分析来自供应商和数据库的交付预测，我得到以下数据数组：
Array
(
[0] => Array
(
[delivery_date] => 2012-05-10
[imported] => 2012-05-10 11:20:37
[qty] => 114
)
[1] => Array
(
[delivery_date] => 2012-05-10
[imported] => 2012-05-11 11:20:37
[qty] => 228
)
[2] => Array
(
[delivery_date] => 2012-05-10
[imported] => 2012-05-15 11:20:37
[qty] => 380
)
[3] => Array
(
[delivery_date] => 2012-05-10
[imported] => 2012-05-16 11:20:37
[qty] => 380
)
[4] => Array
(
[delivery_date] => 2012-05-10
[imported] => 2012-05-17 11:20:37
[qty] => 380
)
)
我的问题是客户每天都没有给出完全相同的预测——这很正常，但是当客户在 2012 年 5 月 10 日没有预测他们需要 x 件产品时，我需要绘制出“缺失”的日期。
我对可能解决方案的想法是：
- 以某种方式与数据数组混合以填充缺少“导入”日期的空值
- 以某种方式将 Google 动态图配置为显示缺失值，而不是从点到点绘制线。
但是到目前为止，我本人还没有成功地使用这些选项中的任何一个:(

echo "data.setValue($jrk, 1, new Date (".$date_import."));\n";
echo "data.setValue($jrk, 2, ".$row[qty].");\n";
$jrk++;
