这是我的控制器
public function actionStudentChart()
{
$stu_track_id = Yii::app()->user->getState('stu_track_id');
$model = MarkDetails::model()->findAllByAttributes(array('mark_stud_track_id' => $stu_track_id ));
$stu_inst_id = Yii::app()->user->getState('stu_inst_id');
$stu_class = Yii::app()->user->getState('stu_class');
if(SchoolSubjectDetails::model()->findByAttributes(array('school_subj_inst_id' => $stu_inst_id , 'school_subj_class' => $stu_class)))
{
$schoolsubmodel = SchoolSubjectDetails::model()->findByAttributes(array('school_subj_inst_id' => $stu_inst_id , 'school_subj_class' => $stu_class));
}
if(!empty($schoolsubmodel->school_subject) && is_array(explode(',',$schoolsubmodel->school_subject)))
$schoolsubmodel->school_subject=explode(',',$schoolsubmodel->school_subject);
$submodel = array();
$sub_label = array();
$sub_name = array();
$marks[0] = array(90,80,80);
$marks[1] = array(90,80,80);
$marks[2] = array(90,80,80);
$marks[3] = array(90,80,80);
$marks[4] = array(90,80,80);
for($i=0 ; $i<count($schoolsubmodel->school_subject) ; $i++)
{
$submodel[$i] = SubjectDetails::model()->findByAttributes(array('subject_id' =>$schoolsubmodel->school_subject[$i]));
$sub_label[$i] = $submodel[$i]['subject_label'];
$sub_name[$i] = $submodel[$i]['subject_name'];
}
foreach($model as $val)
{
for($i=0;$i<count($sub_label);$i++)
{
$mrk[$i][]=$val[$sub_label[$i]];
}
}
$this->render('studentchart',array(
'model'=>$model,'sub_label'=>$sub_label,'sub_name'=>$sub_name,'marks'=>$marks,'mrk'=>$mrk,
));
}
这是我的观看页面
if(!empty($model))
{
for($i=0 ; $i<count($model) ; $i++)
{
$exam_type[] = $this->_exam_type[$model[$i]->mark_exam_type];
}
for($i=0 ; $i<count($sub_label) ; $i++)
{
$chartData1[] = array( "name"=>$sub_name[$i] , "data"=>$marks[$i]);
$chartData2[] = array( "name"=>$sub_name[$i] , "data"=>$mrk[$i]);
}
$this->Widget('ext.highcharts.HighchartsWidget', array(
'options' => array(
'chart' => array('type' => 'bar'),
'title' => array('text' => false),
'xAxis' => array(
'categories' => $exam_type
),
'yAxis' => array(
'title' => array('text' => 'Marks Obtain')
),
'series' => $chartData1
)
));
$this->Widget('ext.highcharts.HighchartsWidget', array(
'options' => array(
'chart' => array('type' => 'bar'),
'title' => array('text' => false),
'xAxis' => array(
'categories' => $exam_type
),
'yAxis' => array(
'title' => array('text' => 'Marks Obtain')
),
'series' => $chartData2
)
));
}
这里我试图从我的markdetails表中显示图表我已经在数据和主题名称中删除了标记并将名称和数据数组传递给图表小部件的系列现在问题是如果我给静态显示图表的值如果我从数据库图中得到的值没有绘制。
这里我打印并检查chartData1和chartData2都有相同的值，但当我将此值传递给我的小部件时，chartData1绘制了图表，其中mapData2“data”数组未通过，因此图表未绘制

答案 0 :(得分：0)
在控制器更改foreach中
foreach($model as $val)
{
for($i=0;$i<count($sub_label);$i++)
{
$mrk[$i][]=intval($val[$sub_label[$i]]);
}
}
这是有效的，终于得到....................
