What happened?

I tried to display a Plotly chart in a Jupyter notebook. After some debugging, I’ve managed to narrow down the issue. The following works perfectly:

import plotly.express as px
import numpy as np

px.line(y=np.linspace(0, 1, 1_000))

Result:

The following fails:

import plotly.express as px
import numpy as np

px.line(y=np.linspace(0, 1, 1_001)) # 1000 + 1

Result:

FYI - I’ve tried this at my end, and I’m not seeing this behaviour, I’ve tried 1_000_000 and I’m not running into this issue.

Oh thanks @DonJayamanne - I actually haven’t reproduced this issue recently anyway. Thanks for the help though!
