烧瓶中的空白图

Question

我对plotly + flask集成比较陌生。

我正在尝试在烧瓶服务器上绘制条形图。这是我的方法。

@app.route('/transactions_plot', methods=['GET'])
def get_transaction_plot():
   exp_category = {'x':['giraffes', 'orangutans', 'monkeys'],
               'y': [20, 14, 23]}
   my_plot_div = px.bar(exp_category, x='x', y='y')

   graph1Plot = plotly.offline.plot(my_plot_div, 
                config={"displayModeBar": False}, 
                show_link=False, include_plotlyjs=False, 
                output_type='div')

   return render_template('index.ejs',graph1Plot=Markup(graph1Plot))

当我检查graph1Plot时得到此输出。

'<div>\n        \n        \n            <div id="72221a07-faa7-48f9-94eb-a802982d4369" class="plotly-graph-div" style="height:100%; width:100%;"></div>\n            <script type="text/javascript">\n

          }
        });
      });

})(jQuery);
</script>

html上的输出图是

有人可以在这里指出我的错误吗？

谢谢。

我对图形的显示方式也有类似的问题，但是我没有以相同的方式发送图形，因此对图形数据进行索引是解决它的关键：

Plotly.newPlot('transaction_graph',graphs[graphIdx].data,{});
