With Bokeh, how to save to a png or jpg instead of a html file?

Question

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

Usually I do

output_file("test.html")

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".

Answer 1

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

Exporting PNGs looks like this

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

And exporting SVGs looks like this

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

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

Answer 2

OK, correcting to myself, I miss your part about not using the preview/save... Currently we do not provide a direct programmatic way to export Bokeh plots to a png file. You will need the user interaction even using internal functions. We could probably add a feature like that in the feature.

Cheers.

I asked a similar question yesterday. The linked solution may work for you. Basically you open the file in a web page, take a screen shot which you can then crop and save as an image.

Python open html file, take screenshot, crop and save as image
