A simple dot file

digraph switches { sw1 -> sw2; sw1 -- sw3; }

gives the error null function or function signature mismatch

I am seeing the same issue, so I don't know why this is marked as closed. @RobVerduijn did you find a fix?

Hello, it's not broken, works as designed I was using a non directional edge in a directional graph

a--b is non directional, if you wish to use this in a directional graph you need to add a direction none behind it

so in a directional graph:

digraph switches {
sw1 -> sw2;
sw1 -> sw3[dir=none];
}

or in a graph

graph switches {
sw1 -- sw2;
sw1 -- sw3[dir=forward];
}

at best there could be a more friendly error
