Graphics, Figures & Tables ⇒ Tikz Chart Arrows

[nerazzurri53]

Hi everyone,

I am a beginner in Latex. Just now I tried to make a chart with four elements, see Attachment.
Here is my code, i don't quite know about how to create exact the arrows as shown in the example.can anyone be helpful? The bend arrows are from my code.

Hi Bartman,

thank you for the prompt answer!
Could you pls explain what the 'yshift' and east mean?
and: out=70, in=130, looseness=1.5, what do they stand for?
Sorry i am completely new about Latex.

[Bartman]

You will find descriptions and examples of everything in the manual of pgf/TikZ. In my opinion, the yshift option is self-explanatory. east is an anchor name. The options out, in and looseness are used in different contexts, in this case with the edge operation.
