Which library am I using?
Working with plotly (3.10) and plotly_express (0.3.1). Here’s the sample code:
line_fig = px.line(multiplayer_df, x='date', y='statPoints', color='name')
line_fig.update_layout(title_text='test', title_x=0.5, xaxis_rangeslider_visible=True, legend=dict(x=-.5, y=-2))
line_fig.update_yaxes(title_text='Cumulative Points')
st.plotly_chart(line_fig)

I completely missed the wide-mode setting sorry; plotly adjusted itself accordingly (here is the end result).
