Graphics, Figures & Tables ⇒ tikZ | Align Nodes in Flowchart

[usr345]

I made a simple flowchart and have 2 questions:

1. How to align the bottom nodes, so they are at the same horizontal level?
2. How always to put "yes" and "no" nearby the 'if' icon, so they are 2mm from the edge of the nearby node?

Please, disregard the Russian text.

Your code is too complex and a bit confusing to discuss all the details. So I can only give some hints.

I suggest to drop the nodes "node-5-1" and "node-10-1" and position the nodes "node-7" and "node-11" directly. You can not only position nodes left, right, above or below others, but also e. g. »below right« with e. g. »node distance=1cm and 2cm«. You should proceed this way in any other cases you used these "helper" nodes. For details see the pgf/tikZ user guide.

I suggest to drop the nodes "node-5-1" and "node-10-1" and position the nodes "node-7" and "node-11" directly. You can not only position nodes left, right, above or below others, but also e. g. "below right"

I did as you said and got rid of the helper nodes:

Code: Select all

\node [question, below = of node-2] (node-3) {ИПУ установлены?};
\node [question, below right = 1.7cm of node-3] (node-5) {Жилое помещение?};

But is it possible to position the node relative to 2 nodes?

Code: Select all

\node [block, below= of node-5.south] (node-6) {21};
\node [block, below right= of node-5.south east, right = of node-6] (node-7) {20};

Cause it's very hard to calculate the millimeters. And now it is only to the right of node-6. "below right= of node-5.south east" declaration is ignored.

I made it with the help of my Russian fellows.

Here is the solution:

Code: Select all

\node[block] at (node-5-1|-node-6) (node-7) {20};

node-5-1 is the helper node to the right of the fork. It's better to use a \coordinate instead of an empty \node there.

Or

Code: Select all

\node[block] at ([xshift=10mm] node-5.east|-node-6) (node-7) {20};

Without the helper node.
