Description

bug

Setting only the upper or lower bound for axes in plotly (introduced here) does not work (at least in scatter plots). If one of the bounds is set to None, the range does not change at all.

import plotly.express as px

fig = px.scatter([0,6])
fig = fig.update_yaxes(range=[0, None])
display(fig)
