Graphics, Figures & Tables ⇒ How can I draw plots in LaTeX?

[Stefan Kottwitz]

As far as I know, pgfplots uses Gnuplot as back-end.

pgfplots evaluates expressions using the pgf math parser, so it's able to work without an external program such as gnuplot. It can work with gnuplot, if specified, such as by

Code: Select all

\addplot gnuplot[..]{...}

but it works fine also without it.

When I use pgf plots and \addplot gnuplot[..]{...}

I could not typesett file.

On the web page, where I download the original picture it says that windows users my have to rename wgnuplot to gnuplot. It possible that this is the reason why graphs are not plotted?(I have already named gnuplot in the icon, where I click to open program)

And is it possible, that I can confirm or check that I all use of external programs with--enable-write18 successfully?(Although I follow instructions completely)

What did you try? Which code did you use for testing? I recommend take code from the pgfplots manual.

I guess you did not understand: use \addplot without gnuplot to avoid using gnuplot. pgfplots can work without it.

I could not typesett file.

Please provide further information, such as: what source code did you try, what happened, which error message did you get, perhaps the .log file.

And is it possible, that I can confirm or check that I all use of external programs with--enable-write18 successfully?(Although I follow instructions completely)

We don't know what you did. You did not tell which editor you used. In case, that you switched to TeXworks, as recommended, you did not confirm it. If you would like to discuss your settings, post details or (better) screenshots.

I guess you like it to read understandable answers, code, clear explanation, screenshots - so please post also questions with code, error messages, screenshots of problematic editor settings, post all information possible.

If the question remains vague and without details, other users hardly can help you.

With pgf I was able to plot pictures("normally". The problems was just with \addplot gnuplot[..]{...} option.

As with original question:

If I typeset file(that one http://www.texample.net/tikz/examples/gnuplot-basics/) I get the same picture(that I post at the beginning), wheather I use PCTeX or MIKTeX. I alredy post log file for MIKTeX, here is one for PCTeX.

And yes, with MiKTeX I use TexWorks.

I see, so the general problem regarding producing plots is perhaps solved.

And yes, with MiKTeX I use TexWorks.

Can you please post a screenshot of your TeXworks "Tool Configuration" settings, for pdfLaTeX, corresponding to the one described by me and posted by Thorsten earlier?

It is not in English, I hope this wont be a problem.

[Stefan Kottwitz]

I see - move the --enable-write18 entry up to the top, so it cannot be confused with the file name, use the upwards arrow button at the right.

Stefan

[ditka]

I did. Nothing has changed.

[Stefan Kottwitz]

Well, let's wait a bit, somebody with MiKTeX has to check it. I'm working with TeX Live.

Possibly, although it is possible that something else is wrong, since I get exactly the same output using PCTeX or MIKTeX.

What about gnuplot and wgnuplot?(question I asked before). Is there any relevant file, that I can rename?
