堆积条形图 returns 意外输出（Python，plotly）
Stacked bar chart returns unexpected output (Python, plotly)
我有一个包含三列的 df（Day-Shift、State、seconds）。
Day-Shift State seconds
Day 01-05 A 7439
Day 01-05 STOPPED 0
Day 01-05 B 10
Day 01-05 C 35751
Night 01-05 C 43200
Day 01-06 STOPPED 7198
Day 01-06 F 18
Day 01-06 A 14
Day 01-06 A 29301
Day 01-06 STOPPED 6
Day 01-06 A 6663
Night 01-06 A 43200
我构建堆积条形图的代码是：
import plotly.express as px
fig = px.bar(df, x="Day-Shift", y="seconds", color="State")
fig.show()
但它 returns 这个堆积条形图。
这里的错误是Day-Shift顺序被改变了，对应的秒数不在这个图表中。我无法识别错误。非常感谢您的支持！

你的代码片段似乎 运行 我这边没问题：
import plotly.express as px
fig = px.bar(df, x="Day-Shift", y="seconds", color="State")
fig.show()
并生成此图：
那么这可能是您的版本问题，或者更有可能是您的数据问题。您应该做的第一件事是确保 none 的数据已转换为索引。您可以使用 df = df.reset_index() 轻松重置索引。在下面的代码片段中，您会看到我将您的相同数据集用作没有索引的字典。
编辑：x 轴格式
在上图中，plotly 将您的 x 轴解释为时间值。如果您想阻止这种情况，只需包含 fig.update_xaxes(type='category') 即可：
