python - Plotly 子图：IndexError：元组索引超出范围

Question

我正在尝试运行 Plotly 教程以在（https://plot.ly/python/creating-and-updating-figures/）上制作子图：

from plotly.subplots import make_subplots
fig = make_subplots(rows=2, cols=1)
fig.add_trace(go.Scatter(y=[4, 2, 1], mode="lines"), row=1, col=1)
fig.add_trace(go.Bar(y=[2, 1, 3]), row=2, col=1)
fig.show()

我收到以下错误：

---------------------------------------------------------------------------
IndexError                                Traceback (most recent call last)

      1 from plotly.subplots import make_subplots

      4 fig.add_trace(go.Bar(y=[2, 1, 3]), row=2, col=1)
      5 fig.show()

IndexError: tuple index out of range

任何想法如何纠正？先感谢您。

只需将listas 传递给tuple：

from plotly.subplots import make_subplots
### specify it next time
import plotly.graph_objects as go

fig = make_subplots(rows=2, cols=1)
fig.add_trace(go.Scatter(y=tuple([4, 2, 1]), mode="lines"), row=1, col=1)
fig.add_trace(go.Bar(y=tuple([2, 1, 3])), row=2, col=1)
fig.show()

结果：
