I am producing two figures with the pgfplots package, where one is on top and another one is on bottom. There is blank space between them. How do I remove that blank? Additionally, how can I make all content to be as wide as \textwidth?

This produces the following:
It seems there a little blank space to the left of the figure, so the figure is a little bit to the right. How can I remove this blank space too? How to align all the labels and y axes? I guess it is difficult. Using groupplot may do these, but how to draw multiple y axes?
groupplotenvironment for this task? It may also help to simplify your work, because currently, you're using eight different axis environments across two TikZ picture environments just to create a single graph. – gz839918 Sep 22 '23 at 08:41groupplotwith multiple y axes. – Y. zeng Sep 22 '23 at 08:49pgfplots? You'd probably have more options stacking two plots insidepfgplotsand have more control over margins (guess). You could try to appendinner sep=0pt, outer sep=0pttotikzpictures options but I doubt it will have a good effect. Finally, try to make a custom style and avoid repetitions. This answer provides example on using multiple parameters in custom styles. – Celdor Sep 22 '23 at 10:55! Package pgfkeys Error: I do not know the key '/pgfplots/inner sep', to which you passed '0pt', and I am going to ignore it. Perhaps you misspelled it.. Let me check it now. – Y. zeng Sep 22 '23 at 11:00inner sepandouter separe keys in/tikz/namespace and are usually used to set inner and outer margins fortikznodes. I meant to append them intikzpicturein the following way:\begin{tikzpicture}[inner sep=0pt, outer sep=0pt]...\end{tikzpicture}. However, I tested it and it doesn't work anyway. You could also have a look at section 4.20 The Picture’s Size: Bounding Box and Clipping of the documentation and see if you could reduce bounding box to inner axes. – Celdor Sep 22 '23 at 11:21
