I am trying to plot a graph like this in Latex:
It turns out to be looking like this with out a line:
This is my tex file
\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage{pgfplots}
\pgfplotsset{compat=1.5}
\begin{document}
\begin{center}
\begin{tikzpicture}
\begin{axis}[
axis lines = left,
ytick={0,0.25},
xtick={0,2,4,6,8,10},
height=5.5cm,
width=13cm,
xmax=10,
ymax=0.25,
ymin=0,
xmin=0,
xlabel = T,
ylabel = k,
]
\addplot [
domain=0:100,
samples=1000,
color=blue,
]
{0.001^(x/x+1) * (1+x)};
\addlegendentry{\(T=p^{\frac{k}{k+1}(k+1)}\)}
\end{axis}
\end{tikzpicture}
\end{center}
\end{document}
Have I done any thing wrong? Thank you.
Simple math problem: (x/x+1) != (x/(x+1))

\addplot [
domain=0:10,
samples=100,

]
{ (1+x)*0.001^(x/(x+1)) };
\addlegendentry{\(T=p^{\frac{k}{k+1}}(k+1)\)}
\end{axis}
\end{tikzpicture}
\end{center}

I try to achieve that different style classes are chosen in a self-defined tikz function depending on the input number.
However, the \ifnum command doesn't seem to work as I expect it.
The error message that I get is:
> thesis/image/outline_MWE.tex:46: Missing = inserted for \ifnum.
<to be read again>
}
l.46 \makeoutlinefig{1}
thesis/image/outline_MWE.tex:46: Missing number, treated as zero.

You can avoid the problem like this:
\documentclass[varwidth=true]{standalone}
\usepackage{tikz}
\usetikzlibrary{shapes,arrows,arrows.meta, calc, decorations.markings, backgrounds,fit,positioning,plotmarks, intersections, patterns, intersections,decorations.text,external,decorations.pathreplacing}

text width=3.0cm,
minimum width=1.5cm,

minimum height=2.0cm,
dashed,

},
activebox/.style = {
box,
draw=red,
thick,
solid
},
node distance = 0.5cm,
]
\ifnum#1=1
\def\mystyle{activebox}
\else
\def\mystyle{box}
\fi
\node[\mystyle, text width=\threebw] (b1) at (0,0) {\textbf{1. Chapter}};
\ifnum#1=2
\def\mystyle{activebox}
\else
\def\mystyle{box}
\fi
\node[\mystyle, text width=\threebw, below = of b1] (b2) {\textbf{2. Chapter}} ;
\draw [-Stealth,ultra thick] (b1) -- (b2);
\end{tikzpicture}

In the following plot, I am getting a warning. I know it has to do something with the coordinates but can't solve it for sure. If anyone can guide me in the right direction, it would be really helpful.

These warnings arise because you are not only filling this path, you are also drawing the markers and the label markers in the same step.
If you decompose this into two separate steps, you can avoid the warnings:

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}
Output:
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}
In pgfplots, when plotting a function, the default domain in -5:5. I would like to set this to be xmin:xmax by default. Is there a way to do this? In other words, I would like to be able to write
\addplot {x^2};
instead of
\addplot[domain=xmin:xmax] {x^2};
To be more specific, here is a MWE of what I look for (and does not work):
\documentclass{article}
\usepackage{pgfplots}
\pgfplotsset{domain = min:max}
\begin{document}
\centering
\begin{tikzpicture}
\begin{axis}[xmin=-10, xmax=10, xlabel = $x$, ylabel = {$f(x) = x^2$}]
\addplot{x^2};
\end{axis}
\end{tikzpicture}
\end{document}
\documentclass{article}
\usepackage{pgfplots}
%What you really need!
\newcommand\Min{-10}
\newcommand\Max{10}
\pgfplotsset{domain = \Min : \Max}
\begin{document}
\centering
\begin{tikzpicture}%x^2
\begin{axis}[xlabel = $x$, ylabel = {$f(x) = x^2$}]
\addplot{x^2};
\end{axis}
\end{tikzpicture}
\begin{tikzpicture}%-(x^2)
\begin{axis}[xlabel = $x$, ylabel = {$f(x) = -(x^2)$}]
\addplot{-x^2};
\end{axis}
\end{tikzpicture}
\end{document}
