Strange error for passing parameter to forestset to draw tree












5















I am trying to draw a simple probability tree, where the probabilites could sometimes be fraction or decimals., this means, I will have to adjust the spacing. So I tried the below code. This produces tree but label gone, and error thrown.



documentclass{article}
usepackage[utf8]{inputenc}

usepackage[linguistics]{forest}
usepackage{philex}


forestset{
my edge label/.style 3 args={
edge label={node[midway, font=sffamilyscriptsize, #1,xshift=#2]{#3}},
},
}

There are actually 2 issues.





  1. style 3 args does not exist, use style n args={3}{... instead.

  2. You define for the 2nd argument xshift=#2 but add one more xshift when you are saying my edge label={above}{xshift=-2mm}{0.002}.


Working code:



documentclass{article}
usepackage[utf8]{inputenc}

usepackage[linguistics]{forest}
usepackage{philex}


forestset{
my edge label/.style n args={3}{
edge label={node[midway, font=sffamilyscriptsize, #1,xshift=#2]{#3}},

Simpler code: pgfkeys already accept comma-separated arguments, which is illustrated in my edge label={above,xshift=-3mm}{0.002}. And instead the xshift you my just use above left or below left etc., as in my edge label={below left}{0.998}.

  • No, not default, just optional (so even if i do not pass anything, nothing happens foreg, what happens if i did not send xshift value - result should be if what if i did not use xshift in the style)
