Some rights reserved under creative commons license.Mon, 03 Jun 2013 04:14:35 -0500Why does graph plotting crop so aggressively, and what is a work-around?http://ask.sagemath.org/question/8016/why-does-graph-plotting-crop-so-aggressively-and-what-is-a-work-around/Surely, the Sage community is aware of this bug. For example, there is [this ticket](http://trac.sagemath.org/sage_trac/ticket/7299), in which the problem is supposed to be fixed. But it's not!
A patch is described: in `sage/graphs/graph_plot.py` we can add the line(?)
> `G._extra_kwds['axes_pad']=.05 `
Am I to change this value in order to fix this over-zealous cropping behavior? No matter what I do, in this regard, I still end up with graph vertices partially cut off.
What's the easy work-around? I would like to be able to plot `graphics_array` objects with several graphs (with their vertices clearly shown!).

http://ask.sagemath.org/question/8016/why-does-graph-plotting-crop-so-aggressively-and-what-is-a-work-around/?comment=21960#post-id-21960Can you post code that replicates the problem and the Sage version you are using. In 4.6.2 I do: sage: g = Graph({0:{1:'a'}, 1:{2:'b'}, 2:{0:'c'}}); g.plot() --- and I get a nice triangle, no cropping occurs. I tried a bunch of other graphs from the database and they all seem fine too.

http://ask.sagemath.org/question/8016/why-does-graph-plotting-crop-so-aggressively-and-what-is-a-work-around/?comment=21959#post-id-21959Ah.. it's probably because the `axes_pad` doesn't get passed to the graphics array.

http://ask.sagemath.org/question/8016/why-does-graph-plotting-crop-so-aggressively-and-what-is-a-work-around/?comment=21957#post-id-21957Thanks. I wasn't using the keyword `axes_pad` explicitly, but rather trying to hack the `graph_plot.py` module. This works.Mon, 21 Mar 2011 10:59:31 -0500http://ask.sagemath.org/question/8016/why-does-graph-plotting-crop-so-aggressively-and-what-is-a-work-around/?comment=21957#post-id-21957Comment by Jason Grout for <p>Try this:</p>
