使用以下代码，我在节点周围得到了奇怪的虚线边框。我可以通过 来摆脱它们line width=0pt，但是为什么它们首先应该在那里？另外：我认为即使使用line width=0pt它们也只是略微存在。
\documentclass[a2paper]{article}
\usepackage{tikz}
\usetikzlibrary{shapes,arrows,chains,positioning,calc,trees,mindmap,backgrounds}
\tikzset{
isNode/.style args = {color#1connected to#2}{concept, concept color=#1, alias=this,
append after command = {\pgfextra{ \draw[dashed,ultra thick,red] (this)--(#2); }}
},
toNode/.style = {concept, concept color=#1},
isConc/.style = {concept, concept color=orange},
toConc/.style = {concept, concept color=orange},
is6/.style = {isNode = color blue connected to othernode}, % use line width=0pt here
to6/.style = {toNode = blue}
}
\listfiles
\begin{document}
\begin{tikzpicture}
\node[fill=red, circle] (othernode) at (7,7) {adsf};
\path[mindmap, isConc] (0,0cm) node[isConc] {Statistic} [clockwise from=90]
child[toConc] { node[isConc] {general theory}
child[to6] { node[is6] {intro} }
child[to6] { node[is6] {outro} }
}
child[toConc] { node[isConc] {distributions} [clockwise from=-30]
child[to6] { node[is6] {normal} }
child[to6, sibling angle=-60] { node[is6] {binomial} }
}
;
\end{tikzpicture}
\end{document}

答案1
正确答案是添加solid，这样dashed就不会泄漏。感谢 Mark Wibrow 给我这个想法（见评论）。
isNode/.style args = {color#1connected to#2}{
concept, concept color=#1, alias=this, solid,
append after command = {\pgfextra{
\draw[dashed,ultra thick,red] (this)--(#2);
}}
}
附言：马克，如果你将此作为答案发布，我会接受它并删除此处的帖子。
