LinuxQuestions.org - Alternative to LABPLOT for Linux?

Let me preface this by saying I am not an expert in either R nor pgfplots but I will show you some working examples and you can decide whether or not these can or will work for you.

Code:

\documentclass[a4paper,11pt]{article}

\usepackage{pgfplots}

% This is a minimum working example of something I could use in a LaTeX document to produce a decent plot 

\begin{document}

\begin{figure}[htp]

  \centering

  \begin{tikzpicture}

    \begin{axis}[

      %This is where I define my title, x and y-axis labels, grid type, etc...

      title={\tiny{I-V Curves of MOSFET}},

      xlabel={\tiny{$V_{DS}(V)$}},

      ylabel={\tiny{$I_{D}(A)$}},

      grid=major,

      legend pos=outer north east,

      ]

      % The x= and y= are both columns in my data file 'procedure_1a_iv_final', which is in my working directory

      \addplot [black] table [x={Vds}, y={Vgs200}] {procedure_1a_iv_final};

      \addlegendentry{\tiny{$V_{GS}=2.00V$}}

      \addplot [gray] table [x={Vds}, y={Vgs205}] {procedure_1a_iv_final};

      \addlegendentry{\tiny{$V_{GS}=2.05V$}}

      \addplot [brown] table [x={Vds}, y={Vgs210}] {procedure_1a_iv_final};

      \addlegendentry{\tiny{$V_{GS}=2.10V$}}

      \addplot [violet] table [x={Vds}, y={Vgs215}] {procedure_1a_iv_final};

      \addlegendentry{\tiny{$V_{GS}=2.15V$}}

    \end{axis}

  \end{tikzpicture}

  % I can caption the plot or figure and refer to it later in my write-up using \ref{}

  \caption{Put your caption here}

  \label{iv:curves}

\end{figure}



\end{document}

Now, for the same plot in R. You can either just use the R interpreter similar to Pythons' or R studio. But, in essence you build the plot. I could write a script not unlike a Bash script but I prefer R studio(though I typically shy away from IDE's).

Code:

> curves <- read.table("procedure_1a_iv_final", header=TRUE, sep="")

> x <- curves$Vds

> plot(x, curves$Vgs215, col="blue", type="l", ann=FALSE)

> lines(x, curves$Vgs210, col="red", type="b")

> lines(x, curves$Vgs205, col="orange", type="l")

> lines(x, curves$Vgs200, col="yellow")

> title("MOSFET I-V Curves", xlab="Vds Voltage(V)", ylab="Id Current(A)")

Notice, I said 'build' above. This is because plot() by itself begins a new plot. The lines() function will add additional curves to the existing plot.

I myself have just begun to become familiar with R and I really like it. You can import data from Excel, csv files, databases, directly off the web, plain text files containing data(as I have done in the examples above), etc. Plus, there is built-in functionality to normalize the data, find standard deviation, etc.

Anyway, I hope this helps, or at least gives you a better idea of some other options apart from LabPlots. If you have any additional questions, let me know and I will try to answer them.
