使用Bokeh，如何保存为png或jpg而不是html文件? [英] With Bokeh, how to save to a png or jpg instead of a html file?

问题描述

我需要导出使用Bokeh创建的图形和绘图的图片.

I need to export pictures of the graphs and plots I am creating with Bokeh.

通常我会

output_file("test.html")

但是，我想将该图形复制到Excel工作表中. 它不再必须是交互式的，尽管那会很辉煌. 如何将图形导出为图片?使用代码，而不是单击预览/保存".

However, I want to copy that graph into an Excel Sheet. It does not have to be interactive anymore, though that would be brillant. How do I export the graph as a picture? Using code, not clicking on "preview/save".

推荐答案

从散景0.12.6开始，现在可以直接从中导出PNG和SVG Python代码.

As of Bokeh 0.12.6, it is now possible to export PNG and SVG directly from Python code.

导出PNG看起来像这样

Exporting PNGs looks like this

export_png(plot, filename="plot.png")

导出SVG看起来像这样

And exporting SVGs looks like this

plot.output_backend = "svg"
export_svgs(plot, filename="plot.svg")

需要安装一些可选的依赖项. 您可以在《用户指南》的导出图表部分.

There are some optional dependencies that need to be installed. You can find more information in the Exporting Plots section of the User Guide.
