Tikzpicture: Line break in node label to right

Question

How can I introduce a line break into the labels of the end nodes in the following MWE? The Tikzpicture will include the line breaks if I remove the label=right: part and just leave label=' but that centers the labelabove' the node, rather than to the right.

How can I get the label to include the line breaks and also stay to the right of the end node?

Answer 1

Apply the every label/.style={align=left} option:

Note:

• One can also use every node/.style={}, but in this case it seems more appropriate to use every label/.style={} as per TorbjørnT's comment.

• It appears that when using the align= option one can not leave a blank space after the label=right:

  So

    label=right:{Some text \\ Some text \\ Some text}
  

  is ok, but

    label=right: {Some text \\ Some text \\ Some text}
  

  is not.

Alternatively, one could also use a \parbox{} to wrap the content in.
