General ⇒ repeat a drawing

[hany]

Hello
I want to repeat a drawing in certain distances horizontally to form a group;
then move the whole group in certain distances vertically

such as that on page 1 of the included ions.tex


is there a more simple way, as for example using (for each), to make it look like that on pages 5-9 of the included ions.tex

How will I view your answer

Thank you

Hello Hany,

welcome to the forum!

There are several possibilities. I can show some, perhaps I start with just one, maybe Johannes might add another or I do.

• classic macros storing a series of TikZ commands
• \savebox for a TikZ picture, then \usebox to print this box as copies several times
• a TikZ \foreach loop
• TikZ pic objects

Since the first two are classic LaTeX, I show a TikZ \foreach loop solution:

Code: Select all

\begin{tikzpicture}
  \foreach \pos in {0,...,5} {
    \node at (1.85*\pos,0) { \tikz\draw [thick,orange,fill=yellow]
      (.25,.25) -- (.25,0) -- (.5,0)   -- (.5,.25)  -- (.75,.25) --
      (.75,.5)  -- (.5,.5) -- (.5,.75) -- (.25,.75) -- (.25,.5)  --
      (0,.5)    -- (0,.25) -- (.25,.25) ;} ;}

Here, I printed nodes in a loop. I simply placed TikZ pictures in the node - no problem. So I could keep the absolute coordinates here.

Now I wrote a pic solution:

• globally define a pic style with a name, which you can use any time you want (well you could do it locally as well)

  Code: Select all

  \tikzset{
    cross/.pic = {
      \draw [thick,orange,fill=yellow]
        (.25,.25) -- (.25,0) -- (.5,0)   -- (.5,.25)  -- (.75,.25) --
        (.75,.5)  -- (.5,.5) -- (.5,.75) -- (.25,.75) -- (.25,.5)  --
        (0,.5)    -- (0,.25) -- (.25,.25) ;}

Here is an example showing how to place also the text node. It could be part of the pic, or separate. I made it separate here.

I used the calc library syntax to add an offset (0.4,0.4) to the node position, so you need to load calc as above. I always use styles for formatting in nodes.

Thank you Stefan very much.
I am very sorry for the delay in my reply, I had some personal problems that prevented me from working on my drawing.

[Stefan Kottwitz]

Hi Hany,

nice to read from you again! Great that you can continue your work on the document.
