[Tex/LaTex] Create a Shmoo plot with pgfplots/tikz

pgfplotsplottikz-pgf

I'm interested in creating a Shmoo-plot using LaTeX. I have looked through the PGFplot-examples but couldn't find any that looked suitable as a starting template. Google produces nothing as well, and I don't wish to abuse Excel for obvious non-pretty reasons (although it is very easy for this kind of plot).

If a Shmoo-plot is unfamiliar to you, it is a two dimensional (presented as such at least) discrete plot looking something like this:

enter image description here

What I want to produce like the image above, although without the pass/fail text. Do you have any suggestions on how I should approach the problem? Sorry if this is a very simple question, I am a beginner in PGFplots and might have missed an easy solution.

edit: this is a more accurate image of what I'm trying to reproduce. This is almost exactly the style I'm looking for.

enter image description here

the input data formatting can be changed to fit any solution, so it is not considered a problem. For example, it can be (x, y, p/f) such as a simple four point set:

(1, 10, 1)
(1, 11, 0)
(2, 10, 1)
(2, 11, 0)

Finally got a result I was satisfied with, and I'm answering this to help any other poor EE-engineer if they get stuck with the same thing. This is a simple solution compared to the ones discussed in the comments.

[Tex/LaTex] How to draw a plot with a variable line width in pgfplots

Well, here's a start, using a quiver plot. This approach requires that you have a "difference" column for the x and y values. This could also be created on the fly using pgfplotstable, but for the moment, I did it by hand. The joins aren't very pretty, but I can't really think of a way to fix this. Using line cap=round helps somewhat, but of course introduces artifacts at the start and end of the plot.

Here's Napoleon's main group of soldiers marching from Kowno to Moscow and back (data from http://www.datavis.ca/gallery/re-minard.php)

And here's a plot of your sample data, with line cap=rect.

[Tex/LaTex] Stretch y-axis in pgfplots

There's an axis option called y post scale for this:

\documentclass[border=5mm]{standalone}
\usepackage{pgfplots}

\begin{document}

\begin{tikzpicture}
\begin{axis} [
 xmode = log,
 log basis x=2,
 ytick={0,0.5,1},
 xlabel={Input size $n$},
 ylabel={time per input in $s$},
 grid=major,
 grid style={densely dotted},
 legend style={at={(0.425,0.99)},
 anchor=north,legend columns=2},
 ]


 \addplot table[x = size, y expr= \thisrow{time}/(\thisrow{size}/1024)] {
 size time 
 1048576   1024
 8388608   2048
 67108864  4096
 536870912 8192
 };
 \end{axis}
 \end{tikzpicture}
