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:
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.
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)
