Is there a way to get -latex arrow heads to work when using decorations.markings?
documentclass[convert = false, border = 1cm]{standalone}
usepackage{tikz}
usetikzlibrary{calc, arrows, decorations.markings}
begin{document}
begin{tikzpicture}[decoration = {markings,
mark = at position 0.5 with {arrow{-latex}}
}
]
draw[postaction = decorate] (0, 0) circle [radius = 2cm];
end{tikzpicture}
end{document}
I have also tried with {-latex} but that doesn’t work either.
How do you add dimension labels to TikZ pictures? Ideally, it would look something like this:
|<----- dimension ----->|
I would like to do this to show the measurement of both straight lines (i.e. sides of a polygon) and curved lines (i.e. circumference/arc length on a circle). Thanks in advance for your help!
If I have two tikzpictures drawn:
documentclass{article}
usepackage[margin = 1in]{geometry}
usepackage{tikz}
usetikzlibrary{decorations.pathmorphing,calc,shapes,shapes.geometric,patterns}
begin{document}
tikzset{treetop/.style = {decoration={random steps, segment length=0.4mm},decorate},trunk/.style = {decoration={random steps, segment length=2mm, amplitude=0.2mm},decorate}}
begin{tikzpicture}
foreach w/f in {0.3/30,0.2/50,0.1/70} {
fill [brown!f!black, trunk] (0,0) ++(-w/2,0) rectangle +(w,-3);
}
foreach n/f in {1.4/40,1.2/50,1/60,0.8/70,0.6/80,0.4/90} {
fill [green!f!black, treetop] ellipse (n/1.5 and n);
}
end{tikzpicture}
begin{tikzpicture}
shade[bottom color=cyan!60!black, top color=blue!20!white] (0,0) rectangle (10,10);
end{tikzpicture}
end{document}
How could I use the first tikz picture within the second? Can I define the first picture as some variable and then place this variable within the second picture and have the option of defining its exact location (x,y) and its size? For example, if I wanted to place the tree in the middle of the rectangle (5,5) but make the size of the tree half its current size. How would I do this

I would like to create an upside down tree with concentrate edges and labels inside the nodes as labels above them.
Right now I’ve come so far. But I still need the edges to concentrate/combine and put the labels + and * next to the overlapping bit. And I need to add the extra labels x, y, and z to the top nodes.
How do I get the tree from the first image? (The corners do not need to be rounded.) It is not absolutely necessary to use tikz-qtree.
tikzstyle{var} = [draw,shape=rectangle,minimum size=2em,
inner sep=2pt,fill=white!20]
tikzstyle{operator} = [draw=none,fill=none,minimum size=2em,
inner sep=2pt,fill=white!20]
begin{tikzpicture}[grow'=up,level distance=1.25cm,sibling distance=1cm,]
tikzset{every node/.style={var}}
Tree [.7 edge node[auto=right,style={operator}] {$+$};
[.6 edge node[auto=right,style={operator}] {$*$};
[.2 ] [.3 ] ]
[.1 ] ]
end{tikzpicture}
I’d like to have Tikz automatically draw a “bounding box” around some nodes, which can have an arbitrary number of “ports” on the left and right sides that should be given anchors, so that edges of the contained nodes can connect to the ports on the boundaries.
An example: 
I’d like the boundary ports to be evenly spaced automatically, and don’t want to have to specify them one-by-one!
For example, I’d like to somehow say something like this:
documentclass[tikz]{standalone}
begin{document}
begin{tikzpicture} [node distance=2cm]
tikzstyle{foo}=[draw,circle,inner sep=0.4cm]
tikzstyle{arr}=[->, >=latex, shorten >=1pt, semithick]
node[foo] (a) {};
node[foo] (b) [right of=a] {};
node[fill] (l1) [above left of=a] {}; % I don't want to specify these 3!
node[fill] (l2) [below left of=a] {};
node[fill] (r1) [right of=b] {};
draw (a.east) edge[arr] (b.west);
draw (l1) edge[arr] (a.west); % But I would like l1, l2, r1 to exist!
draw (l2) edge[arr] (a.west);
draw (b.east) edge[arr] (r1);
end{tikzpicture}
end{document}
But without manually specifying l1,l2,r1 (I’d rather pass parameters of 2/1 to say 2 ports on the left and 1 on the right). Also, I don’t know how do get the surrounding rectangle to be drawn automatically (with some “padding” between the nodes and the rectangle).
EDIT:
Kevin C’s answer is very nice, but it seems the bounding box takes account of labels (I’d rather it didn’t), and asking for 0 boundary ports, spuriously adds one at the top and bottom of the edge. E.g.
begin{document}
begin{tikzpicture}
tikzset{
foo/.style={draw,circle,inner sep=0.4cm},
arr/.style={->, >=latex, shorten >=1pt, semithick},
}
node[foo] (a) [label=above:$a$]{};
anchorbound{0}{1}
draw[arr] (a.east) to node[above] {$alpha$} (r1);
end{tikzpicture}
end{document}
Looks a bit strange (the a node is relatively lower than I’d like). Can I somehow tell tikz to ignore the labels in the bounding box calculation?
I have two tikzpicture within a figure and I would like to place one tikz relatively to the other tikz nodes. I tried below of= with no success. The two tikz have different arrows and layouts. Here is the code where I need to place the second tikz under the ABC node.
begin{figure}[H]
centering
begin{tikzpicture}[node distance=4cm]

I need to draw a number of `bacteria’ in TikZ. Their coordinates and orientation needs to be random within a pre-defined scope.
I have randomized the orientation successfully, but not the location of each bacterium.
Here is what I have:
documentclass{article}
usepackage{pgfplots}
pgfplotsset{compat=newest}
usetikzlibrary{calc,decorations,decorations.pathreplacing}
begin{document}
newcommand{bacterium}[3]{scalebox{#2}{tikz[rotate=#3]{
coordinate (A) at (#1);
shadedraw[shading=ball,ball color=yellow!75, white,rounded corners=10](A) rectangle++(1.5,.65);
draw[decorate,decoration={snake,amplitude=1mm}](A)++(0,.75*.5)--++(-1,0);}}}
begin{tikzpicture}
foreach x in {1,2,...,10}{
bacterium{rand*10,rand*10}{.2}{rand*360}}
end{tikzpicture}
end{document}
This results in the bacteria orienting randomly but lining up along the x-axis.

What should I do?
Apologies if this has already been asked – I could not find it.
The following is an example of what goes wrong:
In this example I would like it to look just like a regular 2×3 table, but I think the problem is that draw starts from the end of the math, not the end of the cell. (I’d prefer to not just use tabular as I will be arrows between columns ultimately)

I am creating a document with a header image created in TikZ. I have encountered an unusual behaviour that is frustrating my attempts to control the positioning.
If the header is left out (for instance by commenting out header in the code below, the first section begins hard up against the top of the page (in this example). However, with the header image included, called with the macro header, the first section begins lower. The amount it drops down is greater than the separation between the sections.
What is this spacing? Where does it come from? Is there a defined length controlling it?
Ideally I would like to compensate for it in the definition of header in an associated class file and control precisely where the text will begin below the header.

I’d like to create the kind of arrow that shows inner classes in UML, that is, an arrow that starts with an oplus symbol as it can be seen here: http://myumlnotes.blogspot.com.es/2007/01/inner-class.html with Tikz.
Anyone could help me define that arrow?
