[Tex/LaTex] pgfplots – Create multiple plots from one table (rows 0–3, 4–7,…)

foreachpgfplots

Using JMH in java I have created file. Suppose .csv file looks like this (but far bigger):

Is it possible to create plot for each n rows (eg. 0-3, 4-7, ..) in this table?

I'm beginner with pgf and quite so with LaTeX as well.. I did create some plots without cycle, but it would be most useful to have "automatic graph maker" that I would point in the .csv file and would be given graph.

I have combined How to draw a graph from CSV with TeX? , How to plot the first n rows of a table using pgfplots? and axis lable in millions/thousands but I cannot make

\documentclass[tikz]{standalone}
\usepackage{pgfplots}
\usepackage{pgfplotstable}
\usepackage{siunitx}
\usepackage{graphicx}

\pgfplotsset{compat=1.5, width = 12cm, height = 5cm, select coords between index/.style 2 args={
    x filter/.code={
        \ifnum\coordindex<#1\def\pgfmathresult{}\fi
        \ifnum\coordindex>#2\def\pgfmathresult{}\fi
    }
}}
\begin{document}
    \begin{tikzpicture}
        \begin{axis}[/pgfplots/error bars/.cd, x dir = normal, y dir = normal, x explicit, y explicit,title=Lists collections performance,
                    xlabel = Objects,
  legend style={legend columns=-1},
  legend to name={thelegend},
  name={theaxis},
                    ylabel = Add operations ops/s,      
                    y tick label style={ytick scale label code/.code={}, scaled y ticks=base 10:-6, yticklabel={\pgfmathprintnumber{\tick} million},},
                x tick label style={/pgf/number format/.cd, scaled x ticks = false, set decimal separator={,}, fixed},
                    xmin = 1, xmax = 10000,
            ]{lists-results.csv}
        \addplot+[red, mark = o, ultra thick,] [select coords between index={0}{3}]
        table [col sep=comma, ignore chars=\%, x="Param: objects", y="Score",]{lists-results.csv};
        \addplot+[blue, mark = o, thick] [select coords between index={4}{7}]
        table [col sep=comma, ignore chars=\%, x="Param: objects", y="Score",]{lists-results.csv};
        \addplot+[green, mark = o] [select coords between index={8}{11}]
        table [col sep=comma, ignore chars=\%, x="Param: objects", y="Score",]{lists-results.csv};
        \addplot+[purple, mark = o] [select coords between index={12}{15}]
        table [col sep=comma, ignore chars=\%, x="Param: objects", y="Score",]{lists-results.csv};
        \legend{Guava ArrayList(0), Guava ArrayList(500), Guava ArrayList(10000), Guava LinkedList}
        \end{axis}
\node [below] at (theaxis.below south) {\ref{thelegend}};
    \end{tikzpicture}
\end{document}

I have tried something like this, but it doesn't seem to be working

\foreach \n in {0,4...,28}{
    \addplot+[red, mark = o] [select coords between index={\n}{\n+3}]
      table [col sep=comma, ignore chars=\%, x="Param: objects", y="Score",]
       {lists-results.csv};
}

_{^{Additional (marginal) questions would be:}}

_{^{1) Is it possible to shorten the names of Benchmarks?

like "com.group.name.lists.impl.GuavaLinkedLists.testLinkedList" -> "GuavaLinkedLists"}}

_{^{2) Is it possible to add to the name number from other column?

like Benchmarks:"GuavaLinkedLists" and Param: capacity":0 ->"GuavaLinkedLists(0)"}}

_{^{3) Is it possible to multiply two columns to create x axis numbers?

like "Score":3326.423048 and "Param: objects":10000 -> 33264230.48

Is it possible to multiply the x coordinates of a plot by a certain factor using pgfplots}}

_{^{4) How to distribute each column value equally?

_{^{5) How to create horizontal lining?

_{^{6) How to export pdf in console?

Yes, this is possible. The main problem, why your \foreach solution isn't working is, because the \n+3 isn't evaluated. You can test this by, e.g. replacing select coords between index={12}{15} with select coords between index={12}{12+3} in your "manual" solution, which will raise an error.

I think I also have addressed all your "additional (marginal) questions" except for the last two. Regarding 5) I don't like grid lines, but you already have found the solution so I think you can apply that yourself if you really want/need them. And Regarding 6) I am not sure if you really just meant to output a PDF of "the whole document" or maybe just create a PDF of the plot (alone).

For more details please have a look at the comments in the code.
