Help plotting hourly data across multiple days in Plotly

Hi everyone,

I have a dataset with hourly temperature readings (timestamps and values) spanning multiple days, and I’m trying to create a line chart that shows patterns across the same hours for each day.

Ideally, I want the x-axis to represent hours of the day (0 to 23) and have a separate line for each day. This would help me compare how temperatures vary across different days at the same hour.

I’m using Plotly Express, but I’m open to using go.Figure if needed. Any suggestions on the best way to reshape the data or configure the x-axis?

Thanks in advance!
