未定义Yii2图表

问题描述：

我正在尝试使用 Yii2 在图表上显示一些数据。我已经通过作曲家安装了 Yii2 Chart JS 。下面的代码摘自文档

I am trying to show some data on the chart while using Yii2. I have installed Yii2 Chart JS via the composer. Below is the code is taken from the documentation

use practically\chartjs\Chart;

Chart::widget([
    'type' => Chart::TYPE_BAR,
    'datasets' => [
        [
            'data' => [
                'Label 1' => 10,
                'Label 2' => 20,
                'Label 3' => 30
            ]
        ]
    ]
]);

现在，当我刷新此页面时，没有看到任何图表。但是在 inspect->控制台中出现错误

Now when I refreshed this page I not seeing any chart. But in inspect->console I am getting an error

Uncaught ReferenceError：图表未定义

Uncaught ReferenceError: Chart is not defined

更新1

这是我的 composer.lock 文件

我调查了此问题，找到了一些解决方案，但仍然无法执行任务。

I have looked into this issue and found some solutions but still unable to perform the task.

任何帮助将不胜感激。

Any help would be highly appreciated.

答

要显示图表，您必须 echo 小部件结果

To display chart you must echo result of widget

echo Chart::widget([
    'type' => Chart::TYPE_BAR,
    'datasets' => [
        [
            'data' => [
                'Label 1' => 10,
                'Label 2' => 20,
                'Label 3' => 30
            ]
        ]
    ]
]);
