If you look at the help page for showSigOfNodes(), there is an argument 
.NO.CHAR that is listed as an internal function. This controls the 
number of characters that are shown in the graph, and defaults to 20.

You can bump that up to whatever value you see fit, but note that it 
*is* listed as an internal function, so you are stepping into the deep 
end of the pool - if things don't work the way you want, it will likely 
be up to you to figure out why and fix it.

Best,

Jim
