My ultimate purpose is to be able to make entity-relationship diagrams.
I would like to be able to establish relationships between entities using a diamond-shaped object.
First, I tried doing:
state c <<choice>>
PlantUML got mad saying I had to include "allow_mixing". After doing that, it seems to ignore the attribute "<<choice>>".
After that, I tried using digraphs to draw a diamond and hopefully establish connections between them and entities.
So I tried:
digraph foo {
" " [fillcolor=palegreen, style="filled", shape=diamond]
}
To get a clear diamond colored more or less like the classical PlantUML entity colors. This code works individually but when combined with entities I get "Syntax Error?"
In any case, I would really appreciate some help with this.
I am currently taking a class in databases and we have to draw ER diagrams. I would much rather use your software (which is amazing btw) then "Astah UML", which is the one recommended by the professor.
