I have this graph where the times above the nodes is the departure time. How can I format the "+1" better? It stands for the "next day". Now is too big with respect to the time, and also the 'plus' is exaggerated. I was trying to put the "+1" smaller and maybe with a different colour.

How can I achieve this? Thanks!

EDIT: How can I also reduce the white part that covers each edges? (the part in the middle of the edge covered by a number)

  • For the edges, use inner sep=1pt (or any size that suits you). For the clocks, you could scale them using scale=0.8 in the node definition, for example.

I would a bit redesign your image. I suggest to use :

  • quotes library for edges labels
  • at nodes O,A,H,E and D use labels for time information
  • most of styles write as option to tikzpicture:

  • Nicer solution, indeed. Still, I don't understand why I don't get the clock to print, even with your code...

    @SebGlav, I tested (and show result of compilation) with recent MiKTeX and used package versions (article.cls 2021/10/04 v1.4n Standard LaTeX document class size10.clo 2021/10/04 v1.4n Standard LaTeX file (size option) clock.sty 2001/04/10 v0.1 TeXclock tikz.sty 2021/05/15 v3.1.9a (3.1.9a) pgf.sty 2021/05/15 v3.1.9a (3.1.9a).

EDIT

I probably did't read correctly in the first place, you wanted to resize the +1 only. One way to do this is to add a label to your node, containing the +1 and positionned correctly. I tried this (note the style for every node):

\begin{scope}[font=\tiny,every node/.style={inner sep=0pt}]
            \node [above=0.5pt of A] {\clock{15}{30} 15:30};
            \node [below=0.5pt of Orig] {\clock{18}{15} 18:15};
            \node [above=0.5pt of H,label={[scale=0.7]10:$+1$}] {\clock{8}{30} 8:30};

which leads to this:

different labeling

You can see the difference betwenn node H (with label) and node E (with the old style). Here's the complete code where Arrive is also put as a node label:

Not related, but your code could be improved to be shorter, you don't need all those scopes.

I used the \scalebox command to downsize the +1.

The whitespace around the arrow labels is controlled by setting inner sep.

Also, I rewrote your code in a way that felt more natural to me, without all the scopes. Using \foreach is an easy way to set the coordinates and edges, in case you want to add or change any.

Here is the code:

\documentclass{article}

\usepackage{tikz}
\usetikzlibrary{positioning}

\usepackage{clock}

\ClockFrametrue\ClockStyle=0

\newcommand{\orig}{\ensuremath{\mathcal{O}}} % origin position
\newcommand{\dest}{\ensuremath{\mathcal{D}}} % destination position

\tikzset{vertex/.style={circle, thick, inner sep=0mm, minimum width=7mm, draw}}

\begin{document}

\begin{tikzpicture}
\node[vertex, fill=red!30] (Orig) at (0,0) {$\orig$};
\node[vertex, fill=green!30] (Dest) at (8,1) {$\dest$};
\foreach \x/\y/\nm/\lbl in {2/2/A/A,2.3/.5/B/B,3.3/-1.2/C/C,4.2/2.1/H/H,6.4/-.5/L/L,5.9/1.9/E/E} 
    \node[vertex](\nm) at (\x,\y) {\lbl};
\foreach \a\b\lbl in {Orig/B/5,Orig/C/5,B/C/3,B/H/3,B/L/3,C/L/5,E/L/8,L/Dest/8}
    \draw [very thick,-stealth](\a)--(\b) node[circle, fill=white, inner sep=.5mm, midway]{\lbl};
\foreach \a\b\lbl in {Orig/A/5,A/H/5,H/E/3,E/Dest/8}
    \draw [draw=red, fill=black, very thick, arrows={-stealth[black]}](\a)--(\b) node[circle, fill=white, inner sep=.5mm, midway]{\lbl};
\foreach \n\hr\min\day in {A/15/30/,Orig/18/15/,H/8/30/+1,E/10/45/+1,Dest/12/00/+1}
    \node [font=\tiny, above=0.5pt of \n] {\clock{\hr}{\min} \hr:\min${}^{\scalebox{.8}{\day}}$};

\matrix [draw,above left, row sep=1mm, nodes={font=\scriptsize}] at (current bounding box.north east) {
    \node [circle, black, draw, label=right:Hotel] {H}; \\
