creates the following figure
Before you start: For every \begin{tikzpicture}...\end{tikzpicture} in this question I use in real \input{path/picNumber.tex} with the content \begin{tikzpicture}...\end{tikzpicture}. For this question I use only \begin{tikzpicture}...\end{tikzpicture} for a better understanding.
As you can see the label of the x-axis is shifted. Why? This only appears if I introduce a custom unit length between the ticks of the x axis, for example unit length = 10em per .5 units. I'm using a custom unit length between the ticks of the x axis to stretch the width of the figures, because in real I have thousands of data points and if I leave the standard unit length between the ticks of the x axis then my figures getting just black boxes, because ot the amount of data.
How can one center the shifted label?
Thank you for your help and effort in advance!
