Plotly python 子图

Posted 2023-02-18

【中文标题】Plotly python 子图

【英文标题】：Plotly python subplots

【发布时间】：2018-09-11 20:52:18

【问题描述】：

我正在尝试用这两个图制作子图，但无法正常工作。我需要输出是一个“div”，两个图垂直堆叠为子图。通常我只会使用 Matplotlib——但我需要 Plotly 的 3D 带状图。

像这样：

情节 1

情节2

感谢您的帮助！

【问题讨论】：

情节 1 和 2 是通过“fig1”、“fig2”命令以及“div1”和“div2”命令生成的。

好的，还有一件事：你使用'和'而不是'像'Blackbody'替换为'Blackbody'，你能解决你代码中的缩进问题吗？

为了清晰起见，修复了意图并删除了“注释掉”代码。

还有缩进问题以及‘和’。另一方面，您想要哪种布局？ plot.ly/python/subplots .. 可能是堆叠子图？

是的，堆叠子图。我不知道你所说的'和'是什么意思。

【参考方案1】：

来自 Plotly 的用户 Empet 在此处发布了我的问题的解决方案：https://plot.ly/~empet/14824

我添加了一些自定义颜色以使绘图看起来更好。

非常有帮助！谢谢Empet！
