我有两个版本的python文件（如果这是描述它的好方法），旨在在网页上打印条形图（使用mpld3）。一种版本有效，而另一种版本（可以根据需要打印条形图）不起作用。具体来说，索引函数在每个python“版本”中返回的内容是不同的。为什么一个“返回值”导致条形图打印而另一个却不打印？
（为简要说明我的程序应该做什么：SQLite3表中的数据被提取到python变量中，我想用它来使用mpld3创建条形图。条形图应在x上具有轴，由癌症药物引起的不同副作用的名称，并且在y轴上应标出每种副作用的发生百分比。）
作为初学者，请原谅我（可能是非常基本的）错误。谢谢。
这是返回值起作用并打印条形图的python代码。现在返回的是包含生成的条形图的html：

print(values)

plt.ylabel("Percentages of Occurence of Side

plt.title("Bar Chart showing Side Effects of Breast
Cancer Medication(s) With Their Corrresponding Percentages Of

fig = ax[0].figure
bar_chart = mpld3.fig_to_html(fig)
return '''<DOCTYPE html>

else:

以下代码不会创建我要创建的条形图，因为返回给函数的内容不起作用，并且我不明白为什么。这是代码：

return render_template("breastcancer.html", bar_chart =
bar_chart)
else:
return render_template("index.html")
if __name__ == '__main__':
app.run(debug=True)
这是我提到的breastcancer.html文件，应该在后面的代码的索引函数中返回该文件：
