Python plotly Express柱状图：图中没有显示所有唯一的时间桶值，而是以小时值显示俱乐部时间桶

我的CSV内容有三列，如1.1K列。它具有5分钟时间的值，如03:40:00+00:00、03:45:00+00:00等。 我希望该图能够为所有这些不同的时间段绘制柱状图，但它实际上是为每小时的时间段（如03:00、04:00等）绘制图表

我的代码如下

import pandas as pd
import plotly.express as px

df = pd.read_csv("D:/Work/WORK/2021/FEB21/BiPA/nqquery/Issue/5MinTimeBucketHistogramNotWorking1.csv")
graph = px.histogram(df, x='TIME_BUCKET', color='REPORT_NAME', title='Report Category Wise Execution Count (5 minuntes sample size)')
graph.show()

我的CSV内容如下，有1.1K列。整个CSV共享以供参考

输出如下所示

---

您的

df['TIME_bucket']

被plotly解释为连续时间，并在连续的x轴上显示为连续时间。如果您希望按数据帧中出现的方式显示bucket类别的值，只需添加：

fig.update_xaxes(type='category')

如果您还稍微调整了文本的

字体大小

，那么您将得到以下结果：

请注意，我在以下内容中使用了格式化版本的

df['TIME\u bucket']

：

df['buckets'] = [dat[11:16] for dat in df['TIME_BUCKET']]

如果你不这样做，你会得到这样的结果：

使用数据示例完成代码： 非常感谢你@vestland！！！它解决了我的问题：）。再次感谢您的详细解释。
