In pgfplots you can add a node at some fraction of the path by just adding node[pos=<fraction]{<stuff>} after the \addplot command. \documentclass[tikz,border=3mm]{standalone} \usepackage{pgfplots} \pgfplotsset{compat=1.17} \begin{document} \begin{tikzpicture} \begin{axis}[hide axis, width=12cm, axis background/.style={path picture={ \...

I see no reason to use PGF code - you are almost there just by noticing that the spiral can be plotted by {cos(deg(x))},{sin(deg(x)},{x}. I normally love PGFPlots, but this is not a plot(axis, scale, ticks, labels, ...). I believe that the plot function in TikZ is the right way. To straighten the ends of the spiral I let the amplitude decay at the same with ...

Do not use scale in an axis, rather use the width option. And work with symbolic coordinates. You will need lualatex to compile this swiftly. \documentclass{standalone} \usepackage[T1]{fontenc} \usepackage[utf8]{inputenc} \usepackage[margin=0.5in,paper=a4paper]{geometry} %Shrinking margins to 0.5in \usepackage{bm} \usepackage[x11names]{...

I do not know why you think that you can use the poles of tan for cot. If you choose the appropriate poles, you get \documentclass[tikz,border=3.14mm]{standalone} \usepackage{pgfplots} \pgfplotsset{compat=1.16} \begin{document} \begin{tikzpicture} \begin{axis}[% axis lines=middle, axis on top, xlabel=$x$, ylabel=$y$, domain=-2*pi:2*pi, ...

Instead of x filter/.code you want x filter/.append code. Then you only need one version. \documentclass{standalone} \usepackage{tikz} \usepackage{pgfplots} \pgfplotsset{compat=newest} \usepackage{filecontents} \begin{filecontents}[overwrite]{data.csv} # x, y, color, shape, size 1, 3, a, 0, 2 2, 6, b, 0, 2 3, 5, a, 1, 2 4, 4, b,...

How to lower the legend so it doesn't override the x-axis You can change legend location by changing the numbers inside at={(0.5,-0.45)} in legend style=.... You already had this in your file, I just changed the numbers so they work for your plots. Same can be done with xlabel, which was also overlapping some stuff. This time I played with values yshift=-...

As it seems the colors for the marks have to be given extra with the mark options (see MWE below). Interestingly changing \addplot+ to (just) \addplot the outliers aren't shown at all. Together with the "strange" behaviour of \addplot+ not considering the colors given to the not-outlier stuff this may be a bug. Is you think so as well, please ...

From the PGFPlots manual (v1.17) section 8.6 on page 553. To change the number format of the output have a look at the TikZ manual (v3.1.7) section 97 (page 1051), e.g. if you want to output 3 decimal numbers instead of only 2. % used PGFPlots v1.17 \documentclass[border=5pt]{standalone} \usepackage{pgfplots} \pgfplotstableread{ x y ...
