我在主查询中有一个子查询，如下所示：

$subquery = (new Query())->select('COUNT(project_sup_id)')
    ->from('project_supervisors AS sup')
    ->where(['AND','sup.project_ref_id = p.project_id']);

$uQuery =(new Query())->select(['project_id','supcount' => $subquery])
    ->from('projects AS p')
    ->join('LEFT JOIN','project_supervisors AS sup','sup.project_ref_id = project_id')
    ->andWhere('IF(supcount>0, sup_project_status=1, project_status=1)');

我正在尝试根据逻辑编写 where 条件，即，如果从子查询获得的计数大于零，则 where 条件必须为sup_project_status=1else project_status=1。在普通的Mysql中，很容易在where里面写if条件，但在yii2中我不明白如何写。

我有两个系列及其交点。我想在图表上有一个椭圆形，中心位于交叉点。椭圆半径应根据轴单位设置，以显示每个轴的感兴趣区域。

Highcharts.chart('container', {
    series: [
      // first series
      {
        name: 'IPR',
        data: [[0, 30.5],[18.5, 25.4],[30, 19.4],[38, 9.7],[42, 0.02]]
      }, 
      // second series
      {
        name: 'VLP', 
        data: [[2, 0.5],[7, 1],[14, 6],[21, 22],[29, 29.6],[40, 30.3],[50, 27.2]]
      }, 
      // intersection
      {
        name: 'Operating point',
        data: [
          [22.42, 23.35]
        ]
      }
    ],
})

如何以编程方式在相交处绘制椭圆形并进行缩放？
