Question

我对Vue和Python Flask还是陌生的。我一直在寻找Vue提供的一些图表。其中之一是FunnelGraph.js。但是，我不太确定如何将它们集成在一起。

我尝试遵循文档https://github.com/greghub/funnel-graph-js#usage，但是我不确定在哪里使用graph变量。我选择使用它的CDN。

在python的Flask的app.py中，

from flask import Flask, render_template
app = Flask(__name__)

@app.route('/')
def index():
    return render_template('index.html')

@app.route('/about')
def about():
    return render_template('about.html')

if __name__ == "__main__":
  app.run(debug=True)

在about.html中，我有

    <script src="https://unpkg.com/funnel-graph-js@1.3.9/dist/js/funnel-graph.min.js"></script>
    <script>

      var graph = new FunnelGraph({
          container: '.funnel',
          gradientDirection: 'horizontal',
          data: [12000, 5700, 360],
          displayPercent: true,
          direction: 'horizontal'
      });

      graph.draw();
    </script>
  </body>
</html>

在当前设置下，我从chrome inspector控制台收到了错误消息：

funnel-graph.min.js:1 Uncaught TypeError: Invalid attempt to spread non-iterable instance
    at funnel-graph.min.js:1
    at g (funnel-graph.min.js:1)
    at e.value (funnel-graph.min.js:1)
    at new e (funnel-graph.min.js:1)
    at about:21

看起来像FunnelGraph的问题：将data定义为数组时，尽管他们在文档中有此示例，但似乎引发了此错误。要解决此问题，请将数据定义为对象：

var graph = new FunnelGraph({
    container: '#graph',
    gradientDirection: 'horizontal',
    displayPercent: true,
    direction: 'horizontal',
    data: {
        values: [12000, 5700, 360]
    },
});

graph.draw();

我还必须将容器选择器调整为#graph，因为这就是标记中的内容。
