需要绘制一个复杂的图形,其中将包含3种类型的边以及几种预定义的节点类型。
是否可以定义更多(例如,不仅一个默认值)“边缘类型”(或节点类型)以供以后使用?
意思是这样的:
edge [colorscheme=paired12, color=8, fontsize=11, fontname="Arial narrow"];
edge2 [colorscheme=paired12, color=3, fontsize=11, fontname="Arial narrow", style=bold];
edge3 [colorscheme=paired12, color=5, fontsize=14, fontname="Arial narrow"];
node1 -> node2; /* will use the default edge definition from the above */
node2 -> node3 [edgetype=edge2]; /* will use the second edge definition */
node2 -> node4 [edgetype=edge3]; /* and so on... */
上面的ofc不正确-仅用于解释...
最佳答案
如果您了解基本知识,则使用gvpr
很简单:input.dot
digraph test {
node1 -> node2[label="test 1"]; /* will use the default edge definition from the above */
node2 -> node3 [label="test 2", edgetype="edge2"]; /* will use the second edge definition */
node2 -> node4 [label="test 3", edgetype="edge3"]; /* and so on... */
}
filter.gvpr
E {
color="red";
fontsize=11;
fontname="Arial narrow"
}
E[edgetype == "edge2"] {
color="green";
fontsize=11;
fontname="Arial narrow";
style="bold"
}
E[edgetype == "edge3"] {
color="blue";
fontsize=14;
fontname="Arial narrow"
}
带命令
gvpr -c -f filter.gvpr -o output.dot input.dot
将产生
output.dot
文件:digraph test {
node1 -> node2 [color=red,
fontname="Arial narrow",
fontsize=11,
label="test 1"];
node2 -> node3 [color=green,
edgetype=edge2,
fontname="Arial narrow",
fontsize=11,
label="test 2",
style=bold];
node2 -> node4 [color=blue,
edgetype=edge3,
fontname="Arial narrow",
fontsize=14,
label="test 3"];
}
关于graphviz定义更多 "defaults",我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/8195642/
