Useful notes for some of my answers:

The demo option for graphicx simply replaces actual figures with black rectangles; do not use that option in your actual document.

comment Tikz: Equal sized nodes with different text
@Power_Project Similar procedures are performed to select the maximum width for pair of strings second and sixth, third and seventh, and fourth and eighth. Once the maximum widths have been determined, they are used as the widths for the nodes (in the TikZ approach).

comment Tikz: Equal sized nodes with different text
@Power_Project You're welcome. The code is fairly easy once you know how it works: looking at this bit: \settowidth\mylenMaxi{#1}% \settowidth\mylenai{#1}% \settowidth\mylenbi{#5}% \ifdim\mylenbi>\mylenai\relax \setlength\mylenMaxi{\mylenbi} \fi the idea is to compare the widths og the first and fifth strings; initially the max width is set to be the one of the first string and then a conditional test is used; if the width of the fifth string is bigger thatn the one of the first string, the max is updated to be the one of the fifth string.

Please see my updated answer for a solution without hard-coded widths; LaTeX does all the calculations.

@Power_Project Ah, I think I know what you want. Please see my updated answer. No need to do anything. LaTeX can do all the measurements for you :)

comment Hatching in a circle and outside a circle
Comments are not the best place to discuss code. Please refer to the PGF/TikZ manual for a comprehensive explanation of the syntax.

comment Hatching in a circle and outside a circle
In opacity=.6,draw, the opacity=0.6 gives the level of transparency (1 is completely opaque, = is completely transparent); draw is needed to draw the circle.

comment Hatching in a circle and outside a circle
@user143462 In \draw[<->] (0,-5) node (yaxisl1) {} -- (0,5) node[left] {$y$}; this node (yaxisl1) {} puts a node at the initial point, called yaxisl1 (l for left 1 because I'll use a second such node for the other part of the picture) and with empty label; nodes must always have a label even if empty.
