neato -T dot -o output.dot input.dot
i have specify the boundary
but the output seem overide the setting with others
graph [bb="0,0,10,1000"]; node [label="N", width=1, height="0.5", fixedsize=true]; graph [bb="0,0,403,374"];
Can it be able to set the boundary of fixed width with unlimited height,
so that the node can auto arrange by desired region.
Input file: b1858.dot
Output file: b1858a.dot
[erg] Please note in the documentation that the bb attribute is written by the software, but ignored on input.
In general, there is nothing currently in the neato layout that would let one limit the range of positions. Even in post-processing, there is nothing that can cause a layout to shrink except the size attribute, and this scales everything.
Given that your input graph has no edges at all, it is unclear what
you are trying to achieve.
