目前我有一个名为members的SQL数据库，其中包含以下列。
我试图在条形图上显示两个不同颜色系列的条形图。一个显示目标，一个显示总数，但我希望由团队。
目前，我有9个团队的337名学生。每个学生都有自己的目标，总数是他们实际筹集的。我想让图表将所有类似的团队组合在一起，以显示每个团队正在做的事情。
下面是当前代码，它为我提供了图表，但只显示了每个团队中的1名学生，而不是团队中所有学生的累积数。
<?php
$rank = 0;
$sql = mysqli_query($GLOBALS["___mysqli_ston"], "SELECT * FROM members WHERE type = 'student' ORDER BY username ASC");
while($row = mysqli_fetch_object($sql))
{
echo "{\"value\":\"";
$rank = $rank + 1;
echo "$row->total\"},";
}
?>
]
},
{
"seriesname": "Target",
"data": [
<?php
$rank = 0;
$sql = mysqli_query($GLOBALS["___mysqli_ston"], "SELECT * FROM members WHERE type = 'student' ORDER BY username ASC");
while($row = mysqli_fetch_object($sql))
{
echo "{\"value\":\"";
$rank = $rank + 1;
echo "$row->target\"},";
}
?>
为了得到这个，我需要调整什么？ 数据样本如下
