在这里,我想通过动态值绘制折线图。但在我的情况下,为数组的每个值创建不同的不同图...请帮助我,我是第一次执行此任务。谢谢进展
<?php
$modelEmployee=Employee::find()->select(['id','sales','expenses'])->all();
$arr = array('id'=>array(),
'sales'=>array(),
'expenses'=>array());
for($i = 0, $modEm = $modelEmployee; $i < sizeof($modelEmployee); $i++){
$arr['id'] = $modEm[$i]['id'];
$arr['sales'] = $modEm[$i]['sales'];
$arr['expenses'] = $modEm[$i]['expenses'];
print_r($arr);
echo GoogleChart::widget(array('visualization' => 'LineChart',
'data' => array(
array('Year', 'Sales', 'Expenses'),
array($arr['id'],$arr['sales'],$arr['expenses']),
),
'options' => array(
'title' => 'My Company Performance2',
'titleTextStyle' => array('color' => '#FF0000'),
'vAxis' => array(
'title' => 'Scott vAxis',
'gridlines' => array(
'color' => 'transparent' //set grid line transparent
)),
'hAxis' => array('title' => 'Scott hAixs'),
'curveType' => 'function', //smooth curve or not
'legend' => array('position' => 'bottom'),
)));
?>

首先,多个图是因为你在for循环中做回声,所以它只需要一个值并从中创建图。
您必须创建一个值数组并将其传递给图表小部件,如下所示
$graph_data = [];
$graph_data[] = array('Year', 'Sales', 'Expenses');
for($i = 0, $modEm = $modelEmployee; $i < sizeof($modelEmployee); $i++){
$arr['id'] = $modEm[$i]['id'];
$arr['sales'] = $modEm[$i]['sales'];
$arr['expenses'] = $modEm[$i]['expenses'];
$graph_data[] = array($arr['id'],$arr['sales'],$arr['expenses']); //add the values you require as set in the order of Year, Sales , Expenses
} //loop ends here
echo GoogleChart::widget(array('visualization' => 'LineChart',
'data' => $graph_data,
'options' => array(
'title' => 'My Company Performance2',
'titleTextStyle' => array('color' => '#FF0000'),
'vAxis' => array(
'title' => 'Scott vAxis',
'gridlines' => array(
'color' => 'transparent' //set grid line transparent
)),
'hAxis' => array('title' => 'Scott hAixs'),
'curveType' => 'function', //smooth curve or not
'legend' => array('position' => 'bottom'),
)));

试试这个
动作
$model=Employee::find()->select(['id','sales','expenses'])->all();
$data[]=["id","sales","expenses"];
foreach ($model as $item) {
$data[]=[(string) $item['id'],(int) $item['sales'],(int) $item['expenses']];
}
return $this->render('test',['data'=>$data]);
视图
echo GoogleChart::widget(array('visualization' => 'LineChart',
'data' => $data,
'options' => array(
'title' => 'My Company Performance2',
'titleTextStyle' => array('color' => '#FF0000'),
'vAxis' => array(
'title' => 'Scott vAxis',
'gridlines' => array(
'color' => 'transparent' //set grid line transparent
)),
'hAxis' => array('title' => 'Scott hAixs'),
'curveType' => 'function', //smooth curve or not
'legend' => array('position' => 'bottom'),
)));
