如何在plotly (Candlestick)中将Y轴显示为小数而不是指数？

import plotly.graph_objects as go

fig = go.Figure(data=[go.Candlestick(open=[...], high=[...], low=[...], close=[...])])

fig.update_layout(yaxis=dict(tickformat=".2f"))

fig.show()

import plotly.graph_objects as go

fig = go.Figure(data=[go.Candlestick(open=[...], high=[...], low=[...], close=[...])])
fig.update_layout(yaxis=dict(tickformat=".2f"))
fig.show()
