How to force left alignment in TikZ-Tex Stack Exchange?
Thus to force left-alignment, the text needs to be told that it can have more space, which is what the two given solutions do. So we can see that in the original specification, the text thought that it was in a box just big enough to hold itself.
What does TikZ-TeX-LaTeX Stack Exchange do?
What is does is as follows (or at least, the following is equivalent to what it does): it first constructs the node as specified but without the minimum size. It then measures the relevant size of the node and compares it to the specified minimum.
What happens when you pass the minimum size to TikZ?
The part to focus on is what happens when you pass the option minimum size (or height or width) to Tikz. What is does is as follows (or at least, the following is equivalent to what it does): it first constructs the node as specified but without the minimum size.
How is padding used to force left alignment?
As the padding is increased uniformly wherever it is needed, the net effect is to keep the text in the centre of the node. Thus to force left-alignment, the text needs to be told that it can have more space, which is what the two given solutions do.
How to align two tikzpicture plots in latex-stack?
BTW, if you do not intend to add subcaptions to your plots, the subfigure environment is useless, and you can just put your (properly scaled) tikzpictures side by side separated by an \\hfill. Thanks for contributing an answer to Stack Overflow!
What’s the problem with line breaks in TikZ?
The problem, according to the TikZ-PGF manual is that Normally, when a node is typeset, all the text you give in the braces is put in one long line (in an \\hbox, to be precise) and the node will become as wide as necessary (p. 224).
What does matrix of nodes mean in TikZ?
Using a matrix of nodes means that you have to terminate your node using \\\\. I wrapped the calculations and style settings into a corner on line style, which passes its arguments to the inner node.
How does padding affect the size of a node?
The crucial thing to realise is that it does this by increasing the padding. That is, it increases the border between the contents of the node and the shape. So the contents of the node (the text) do not see the increase in size.
