I need to add axes to a bunch of figures in my document, I'm trying with tikz but maybe there's an easier and more elegant way to do it (looking at you, overpic)?
The result I'm trying to achieve is not like this, I need the axes to have the arrows as well.



I got some MWE working, but the axes are vertically misaligned (they should be outside of the picture). I've tryed adding vspaces but they don't seem to work as I'd like.



Thanks in advance for your help!

          • So for the labels (put(.545,.07)x put(.46,.007)y) I just have to try around with the numbers until they are in the right position? Is there no easier way to position them relative to the picture maybe? Or just add labels to the vectors like with tikz?

          • So for the labels (put(.545,.07)x put(.46,.007)y) I just have to try around with the numbers until they are in the right position? Is there no easier way to position them relative to the picture maybe? Or just add labels to the vectors like with tikz?

          • @Superuser27 It is R code embedded in a LateX file (.Rnw) , that knitr (a R package) export to a true/pure LateX file (.tex) that can be compiled as usual . With R (free) and RStudio editor (free) installed, all the process is simply push the "Compile PDF" button. With respect to the unwanted blue line, simply remove the row lines(c(1, ....
