I created this mindmap to illustrate a big system that I built.

enter image description here

As I am describing it, I need to have a small portion of the mindmap along with the text, so that the reader understands better which part I am writing about.

Is it possible to show only a part of the mindmap? Maybe a "zoom in" effect or "isolate" a branch or "focus"? Ideas are welcome. One idea is to have a portion like this:

enter image description here

UPDATED question to show what I got so far and put the code in a single file.

Here is the MWE:

With the suggestions by @jet, executing the code above I get a nice path around the blue part the with \drawcommand. I thought that now that I visually validate the area to be cliped I just substitute \draw with \clip. But what happens is I get the some joints from other nodes:

Here is the picture with the \draw command and next, with the \clip command: enter image description here enter image description here

I believe the problem might be in last part of the tikzpicture, the pgfonlayer. I just used it to link the dark blue node (that is not a child of the main node) to the other nodes. I do not know other way to do it. And I don't want to clip/trim a pdf because I want to keep the nodes referenceable.

    I recall that you can clip a part of your mindmap.

  • @vipa I think the views library only works with rectangle shapes

  • It makes perfect sense to split your figure into a separate file, but NOT for an example where other people are to help you with an unrelated problem. Create a MWE with the problem. Why are you using a background layer? -I believe that is causing the problem. Jun 26, 2020 at 11:10
  • @hpekristiansen Thanks for the note, was not aware that was not a MWE. A MWE is simply done by putting all the tikzpicture code in the main.tex where it says \input{mindmap-texforum1.tikz}. I am using background layer to create connections between nodes that are not childs of the main node (the dark blue node that says Laaaa. I did not know how to do it other way.

    Yes, @hpekristiansen, that is exactly what I was looking for! Thank you very much. I thought the background layer was somehow needed for the path. After all it is not. Cheers

You can clip part of your mindmap with for instance \clip (2.1,-3) rectangle (10,6.8); (pgfmanual v3.1.5b p 84, 6.3 Creating the Lecture Map)

enter image description here

and then in a figure with caption in article

enter image description here

I put your tikzpicture in a standalone file.

foo.tex

  • Thank you @jet, I should have looked better in the pgfmanual. Nevertheless, I would like to clip with a different shape than a rectangle in order to not show the nodes with other colors (the top left corner and bottom left corner in your example).

  • @Pedro you're looking for that type of shape ? tex.stackexchange.com/questions/70999/…. I wonder to what extent you'd be interested in tex.stackexchange.com/questions/542668/… (in the idea)

    @Pedro I tried a workaround (see my edit) to define the coordinates of the clip. you'll still get the edges to other link (you just zoom on your mindmap). But you can defined the shape that fits best.

    Thanks @jet, I will update my question with what I achieved so far. The \draw command works well but the problem arises when I substitute it with \clip.

    Hello @Jet , yes I did. See the answer above. Just remove the pgfonlayer commands and the clip works!
