我正在尝试循环绘制饼图。在我的数组中有 3 个值,我想绘制 3 个饼图。我已经尝试过如下。
<?php foreach($pie as $m)
{ ?>
google.charts.load('current', {'packages':['corechart']});
google.charts.setOnLoadCallback(drawChart);
function drawChart() {
var data = google.visualization.arrayToDataTable([
['Task', 'Hours per Day'],
<?php foreach($piearray[$m] as $kf=>$v){ ?>
['<?php echo $kf;?>', <?php echo $v;?>],
<?php } ?>
]);
var options = {
title: 'Brand Placement'
};
var chart = new google.visualization.PieChart(document.getElementById('piechart<?php echo $m;?>'));
chart.draw(data, options);
} <?php }?>
<script src="https://gstatic.com/charts/loader.js"></script>
<?php foreach($pie as $mi)
{
<div id="piechart<?php echo $mi;?>" style="width: 900px; height: 500px;"></div>
}
}
但它只运行最后一个。请帮助我。
