I'm currently working with tikz and pgfplots to set a few plots. It works marvelously for a lot of applications, add I have set a number of plots (especially surfaces from matlab) with help of the scripts from 3-dimensional histogram in pgfplots.
However, the current plot is over my head. The final result is offset to the axis somehow, but the mapping seems to do fine. I have scoured over several posts like Why do I fail to import external 3D plots with pgfplots?, Problem with external graphics and 3D pgfplots and a few others with no avail.
I added 4 corner points at the limits of the axis to be able to produce the necessary 4 points. those are the black crosses visible in the image.
Below is a MWE:

For some reason, my matlab figure window was in "Docked" mode. This screws with the
as it then always returns
[1 1 w h], which then of course again screws with the pt calculation. Usingfixes that again!
