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

"Benchmark","Mode","Threads","Samples","Score","Score Error (99.9%)","Unit","Param: capacity","Param: objects"

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?
Horizontal space between xticks in pgfplots

5) How to create horizontal lining?
Horizontal lines in bar plots without first line

6) How to export pdf in console?
How to create pdf with command line using MiKTeX?

  • Welcome! There's a key called something like skip rows between, might get you started. (You'll probably get an answer soon, but if not ping me back and I'll take a more detailed look) – cmhughes May 11 '16 at 17:39
  • table/skip first= and sample= might do it. If there had been a MWE I would have tested it. – John Kormylo May 11 '16 at 21:08
  • @cmhughes I added more details in my question, please look at it – Polostor May 24 '16 at 16:54

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.
