I am trying to reproduce the picture below on the left with the packages "tikz" and "pgfplots". But as you can see the best I got was the figure below on the right. In my attempt I modified the tex code from here and adapted it as follows below after the pictures.
My questions are as follows.
How do I translate the "x" and "y" axes such that these axes intersect perpendicularly at the point (0,0)?
How do I position (x,y) coordinates on the graph? How do I position the red circles on the graph?
How do I control the size of the axis legends? And the size or width of the axes? How to change it?
\documentclass{standalone} \usepackage{tikz} \usepackage{pgfplots} \pgfplotsset{compat = newest} \begin{document} \begin{tikzpicture} \begin{axis}[ xmin = -6, xmax = +8, ymin = -2.0, ymax = +11.0, xtick distance = 1.0, ytick distance = 1.0, grid = both, minor tick num = 1, major grid style = {lightgray!25}, minor grid style = {lightgray!25}, width = 1.0\textwidth, height = 1.0\textwidth, xlabel = {$x$}, ylabel = {$y$}, legend cell align = {left}, ] \addplot[ domain = -4:3, samples = 200, smooth, blue, thick, ] %{exp(ln(x+1)/ln(2))}; {2^(x)+1}; \addplot[ domain = -4:3, samples = 200, smooth, red, dashed ] {2^(x)}; %\legend{Plot from expression, Plot from file} \end{axis} \end{tikzpicture} \end{document}
xlabel
.width
andheight
does. Did you mean to ask something else?
