这是第一个系列查询
function student_reports(){
$this->db->select('monthname(a.view_date) as name, count(a.report_id) as
data');
$this->db->from('report_view_track a');
$this->db->where('a.user_id', 1);
$this->db->where('a.preview_mode', "report");
$this->db->group_by('monthname(view_date)');
$this->db->order_by('a.id', 'ASC');
$query = $this->db->get();
}
这是结果：
----------------------
|date | count |
----------------------
|2018-01-12 | 80 |
|2018-02-12 | 100 |
|2018-03-12 | 20 |
|2018-04-12 | 60 |
|2018-05-12 | 50 |
|2018-06-12 | 50 |
|2018-07-12 | 50 |
第二个查询结果是相同格式的不同计数
function parents_reports(){
$this->db->select('monthname(a.view_date) as name, count(a.report_id) as
data');
$this->db->from('report_view_track a');
$this->db->where('a.user_id', 2);
$this->db->where('a.preview_mode', "report");
$this->db->group_by('monthname(view_date)');
$this->db->order_by('a.id', 'ASC');
}

如何在高图区域样条图中以这种格式显示结果 => {数据：[Date.UTC（2017,02,15），50}
