短横线/绘图条形图显示两个相互重叠的条形图，以便显示实际值的两倍

Question

我的仪表板应用程序有问题。从2018年开始，它显示了两个横杆堆叠在一起（视觉上显示110）。但是，悬停时的值仍然是正确的（大约55，并且在减小）。你知道吗

您可以在底部找到代码。

而且，当我和matplotlib.pyplot文件图表显示正确。你知道吗

此外，条之间的细线（大约值55）显示正确的值。这是复制条然后堆叠的地方。你知道吗

堆叠的条形图应消失，以便显示大约55（递减）的正确值。 有没有人知道如何解决这个问题或知道如何解决这个问题？你知道吗

**这是我之前问题的更新-这次，按照建议，我添加了代码并重新编写了描述。谢谢你的建议，科拉尔万达和托尼**
