Graphics, Figures & Tables ⇒ using edge in tikz II

[kenth]

I use edge to place lables along straight line.
I should want to the lines and the node with different colours, see the attached files.
Anybody?

You can have style options for the quoted nodes, such as:

Code: Select all

\draw [red,thick] (A) to ["txt" '{fill=blue,text=yellow}] (B);

While the color (red) is applied to the whole path, this style options override it for the text, and if you use edge instead of to, you can even override the line color, such as:

Code: Select all

\draw [red,thick] (A) edge ["txt" '{fill=blue,text=yellow}, green] (B);

because edge produces its own path.

Great! Thanks.
One last question if I may: How to turn the label as bold?

Hi Kent,

this way: to ["text" '{font=\bfseries}]

Again, thank you very much!

Can we avoid the "-s around the label?

[Stefan Kottwitz]

Hi Kent,

not sure what you mean - in the output, or in the code? In the code "..." is a shortcut for a node syntax, so you can write

Code: Select all

\draw (A) to ["text"] (C);

instead of

Code: Select all

\draw (A) to node [sloped] {text} (C);

To be precise, I want the macro
\def\mgElabel[#1,#2,#3,#4]{
\draw [#4] (#1) edge [#3 {fill=gray!20,text=black,font=\bfseries}] (#2);
}
to work with the label (argument #3) given without sourounding double apostrophes, i.e. text
instead of "text".

In addition, I have the following defined in my .tex file
\usetikzlibrary{quotes}
...
\begin{tikzpicture}[scale=\scalefactor,every edge quotes/.style={fill=gray!20,sloped}]
. . .
\mgElabel[A,C,"text",red];
. . .

\mgElabel[A,C,"text",red] works fine, but, \mgElabel[A,C,text,red] does not.

Hi Kent,

the quotes are needed, but you could put them into the macro definition:

Code: Select all

\def\mgElabel[#1,#2,#3,#4]{
\draw [#4] (#1) edge ["#3" {fill=gray!20,text=black,font=\bfseries}] (#2);
}

Stefan, thanks for your quick and kind responses!
For me, edge has been new.
Up to now I have only used node.
