```python import plotly.express as px gapminder = px.data.gapminder() gapAsia = gapminder[gapminder['continent']=='Asia'] px.line(gapAsia,x='year',y='lifeExp') ``` <img width="1024" height="511" alt="Image" src="https://github.com/user-attachments/assets/b46b8149-d978-47bc-82c5-f46760b14b59" /> ```python gapAsia = gapminder[gapminder['continent']=='Asia'] gapAsia_sort = gapAsia.sort_values(by='year') px.line(gapAsia_sort,x='year',y='lifeExp') ``` <img width="1017" height="511" alt="Image" src="https://github.com/user-attachments/assets/59e89802-3399-42a6-a573-2c53ec7b19a1" /> gapAsia might be the correct line plot i guess. But I wonder why the line plot from gapAsia_sort look like above this. Can anyone figure out it and explain this issue to me?
