Comment (by etn40ff):
Dear All,
thank you for dealing with this while I had not sage to play with.
I am back at it now and I agree with the changes made so far.
One thing I am not convinced of is how the output of `view` looks like:
the
figure is all squashed to the right side.
A possible fix to this is to enclose the output of `latex()` into a
`\makebox[\textwidth]{` `}`. This unfortunately creates some problem with
latex
itself. Somehow if we put things inside a `\makebox` environment then
latex
complains about undefined control sequence `\pgfsys`. The latex code works
perfectly without the `\makebox`. To replicate this do as follows:
With the current code
{{{
sage: c = plot(sin(x))
sage: view(c)
}}}
works but the figure is all squashed to the right.
Apply this patch then and try again
{{{

Apparently the issue is with the axes.
To get the code that sages tries to compile you can do
{{{
sage: from sage.misc.latex import _latex_file_
sage: s = _latex_file_(latex(c))
sage: f = open('/tmp/sage.tex','w'); f.write(s); f.close()
}}}
Any idea on how to tackle this?
One more issue (this, I think, is a bug upstream):
{{{
sage: c = text('Hello World!',(1,0))
sage: latex(c)
...
IOError: [Errno 32] Broken pipe
}}}
