Vertical line in 2d plot using tikzpicture - latex

After plotting on overleaf the following right line
\begin{tikzpicture}
\begin{axis}[
axis lines = left,
xlabel = $x$,
ylabel = {$f(x)$},
]
%Below the red parabola is defined
\addplot [
domain=-10:10,
samples=100,
color=red,
]
{((6*x - 48)/8)};
\addlegendentry{$6x + 8y = 48$}
I need to add a vertical line for x = 6 on the same plot.
Could you help me with that?

Having a look here, one possible solution is the following:
\documentclass{standalone}
\usepackage{tikz}
\usepackage{pgfplots}
\begin{document}
\begin{tikzpicture}
\begin{axis}[
axis lines = left,
xlabel = $x$,
ylabel = {$f(x)$},
]
%Below the red parabola is defined
\addplot [
domain=-10:10,
samples=100,
color=red,
]
{((6*x - 48)/8)};
%% This is the vertical line
\addplot[thick, samples=50, smooth,domain=0:6,magenta] coordinates {(6,0)(6,-15)};
\addlegendentry{$6x + 8y = 48$}
% Added to the legend
\addlegendentry{$x = 6$}
\end{axis}
\end{tikzpicture}
\end{document}

Bounding box coordinates for pgfplot

How can I get the bounding box coordinates for the pgfplot below? I need the coordiates in pgfplot space. (current axis.south west) and (current bounding box.south west), for example, do not give what I need. I'm expecting something like SW = (-7,-1.1), NE = (8.2,1.4), which would extend to the right beyond the red rectangle.

pgfplots "Soft clip" of "Fill between" not working with loglogaxis

I am struggling with soft clipping a fill between when using a loglogaxis. The soft-clip domain seems to be completely off; i.e. setting soft clip={domain=1:1} yields the same result as no domain at all.
Yet a domain soft clip={domain=0:10000000000} results in a horizontal clip:
The pgfplots manual doesn't give an example for clipping on a loglogaxis, might it be it's simply not supported? If it is, can anyone point me on how to clip to soft clip={domain=3.7E4:5.5E5} ?
My MWE:
\documentclass[tikz]{standalone}
\usepackage{pgfplots}
\usepgfplotslibrary{fillbetween}
\begin{document}
\begin{tikzpicture}
\def\xmin{1E4}
\def\xmax{1E7}
\begin{loglogaxis}[
xmin=\xmin,xmax=\xmax,
ymin=1E-2,ymax=1000,
xlabel={Re [-]},

width=15cm,
xtick={1E4,1E5,1E6,1E7},
extra x ticks={3.7E4,5.5E5},
extra x tick labels ={3.7E4,5.5E5},
extra x tick style={
tickwidth=\pgfkeysvalueof{/pgfplots/minor tick length},
tick label style={yshift=-0.5mm}
},
ytick={1E-2,1E-1,1,10},
yticklabels={,,1},
extra y ticks={1E-2,1E-1},
grid=major,
domain=1E4:1E7,
]
\def\D{1.4}
\def\yplus{30}
\addplot[name path = C,thick,domain=1E4:1E7] {\yplus/((1/2*(2*log10(x)-0.65)^(-2.3)*(x/\D)^2)^(1/2)/1000)};
\def\yplus{300}
\addplot[name path = D,thick,domain=1E4:1E7] {\yplus/((1/2*(2*log10(x)-0.65)^(-2.3)*(x/\D)^2)^(1/2)/1000)};
\addplot [gray!30] fill between[of=C and D, soft clip={domain=3.7E4:5.5E5}];
\end{loglogaxis}
\end{tikzpicture}%
\end{document}
You could use the following technique to clip it:

\usepackage{pgfplots}
\usepgfplotslibrary{fillbetween}
\pgfplotsset{compat=1.18}
\begin{document}
\begin{tikzpicture}
\def\xmin{1E4}

extra x ticks={3.7E4,5.5E5},
extra x tick labels ={3.7E4,5.5E5},
extra x tick style={

},
ytick={1E-2,1E-1,1,10},
yticklabels={,,1},
extra y ticks={1E-2,1E-1},

\def\D{1.4}
\def\yplus{30}
\addplot[name path = C,thick,domain=1E4:1E7] {\yplus/((1/2*(2*log10(x)-0.65)^(-2.3)*(x/\D)^2)^(1/2)/1000)};
\def\yplus{300}
\addplot[name path = D,thick,domain=1E4:1E7] {\yplus/((1/2*(2*log10(x)-0.65)^(-2.3)*(x/\D)^2)^(1/2)/1000)};
\draw [

(3.7E4,1E-2) rectangle (5.5E5,1E3);

Graph in Latex using Tikz and PGFplots

How to draw this graph in LaTeX? I have used TikZ but I can't get it done exactly.
This is what I have tried so far:
\begin{tikzpicture}
\tkzInit[xmax=6,ymax=6,xmin=-6,ymin=-1]
\tkzAxeXY
\draw[thick] (6,3) -- (-4,5);
\filldraw[black] (6,3) circle (2pt) node[anchor=west] {A(6,3)};
\filldraw[black] (-4,5) circle (2pt) node[anchor=east] {B(-4,5)};
\end{tikzpicture}
Using regular pgfplots you could do the following: Draw the line with the points you choose and label them with nodes. Then draw the additional distance markers using \draw in the axis coordinate system (The concrete positions of all elements may have to be adjusted).
\documentclass{article}
\usepackage{tikz}
\usepackage{pgfplots}
\begin{document}
\begin{tikzpicture}
\tiny
\begin{axis}[
width = 6cm,
height = 4cm,
ymajorgrids = true,
ymin=-1,
ymax=7,
xmin=-6,
xmax=6,
xtick distance=1,
ytick distance=1,
axis y line*=center,
axis x line*=center,
enlarge x limits=.12
]
\addplot+[sharp plot] coordinates {(6,3) (1,4) (-4,5) } node[below=1mm, pos=0] {A(6,3)}
node[pos=0.45,below=1mm] {P(x,y)}
node[pos=1,below=1mm] {B(-4,5)};
\draw[|-|] (axis cs:1.2,5) -- node [above, rotate=-10] {m=13} (axis cs:6.3,3.9);
\draw[|-|] (axis cs:-3.8,6) -- node [above, rotate=-10, pos=.3] {n=2} (axis cs:1.2,5);
\end{axis}
\end{tikzpicture}
\end{document}

Multiple horizontal bar-charts in a row in latex

I have three horizontal bar-charts that I created using both the Tikz package and PGF plots package in latex. I am using Overleaf. The three horizontal bar-charts look like the following:
Is there a way to nest these horizontal bar-charts in a row in a latex document? I need this in order to save space for a paper I am working on. So what I am looking for is this (note: this 2nd image is meant to illustrate what I am looking for exactly):
