如何将 plotly 图形保存为 jpg

Question

如何将在graph.show()之后创建的以下图形保存为 JPG、PNG 或 PDF 到特定目录？

代码：

    import plotly.graph_objects as go

    graph = go.Figure(data=[go.Candlestick(x=df['Date'],
                open=df['AAPL.Open'], high=df['AAPL.High'],
                low=df['AAPL.Low'], close=df['AAPL.Close'])
                      ])

    graph.show()

Answer 1

一个简单的谷歌搜索告诉我

graph.write_image("name_of_file.jpeg")

Answer 2

这将起作用：

graph.write_image("name_of_file.jpeg")

但是你必须安装万花筒。 从plotly 文档中，您可以看到：

Static image generation requires either Kaleido (recommended, supported as of plotly 4.9) or orca (legacy as of plotly 4.9). The kaleido package can be installed using pip.

$ pip install -U kaleido

或康达。

$ conda install -c plotly python-kaleido
