How to remove grey border framing graph?

[nigeljw3]

Hi,

All the images in the docs have a white background outside the graph, but I get an ugly grey color fill in that area. How can I switch this to white?

Cheers,
Nigel

IIRC, this is the default background. It's grey for the interactive terminal and usually transparent for other backgrounds.

There should be some property to set that:
