从 plotly 保存图像 [英] Saving images from plotly

问题描述

如何以不同格式保存使用 plotly 生成的图像?从生成的 HTML 图形中只能下载为 PNG".我需要与图形进行交互(更改旋转，选择要绘制的数据)并为每个在线修改图保存一个 .eps 图形.非常感谢！

How can I save images generated with plotly in different formats? Only "Download as PNG" is possible from the generated HTML figure. I would need to interact with the figure (change rotation, choose which data to plot) and save an .eps figure for each online modified plot. Thanks a lot!

推荐答案

Plotly 支持导出到 EPS(文档中提到你需要 poppler 库)和 Figure对象有一个 write_image 方法，可以将图形保存到文件中.

Plotly supports exporting to EPS (the docs mention that you need the poppler library) and the Figure object has a write_image method that saves a figure to a file.

您可以通过文件名和分辨率使用 width 和 height 关键字参数指定格式，代表逻辑像素.

You can specify the format through the filename and the resolution with the width and height keyword arguments, representing logical pixels.

您可以在 Plotly 此处阅读有关静态图像导出的更多信息.这是一个代码示例:

You can read more on static image exporting in Plotly here. This is a code example:

fig.write_image("name.eps", width=1920, height=1080)

为了选择绘制的内容，您必须设置图形的相机控件.

In order to select what is plotted you will have to set the figure's camera controls.
