虚化 - 地块的垂直布局

Question

我试图垂直显示两个图。我得到一个错误信息，在 show(column(west_fig, east_fig))

请你帮我理解一下这个错误信息。

版本：BokehJS 1.4.0 BokehJS 1.4.0成功加载。

注：我在Jupyter笔记本上运行这段代码。

Answer 1

在你的代码末尾只做一个show语句。这意味着删除 show(column(west_fig, east_fig)), show(west_fig), show(east_fig) 行，并在代码末尾添加 show(column(west_fig, east_fig))
