in reply to Chart::Gnuplot and Windows XP

Has anybody made Chart::Gnuplot with gnuplot work under Windows XP? Or is this yet another reason to change OS?!
Wow, just wow, the drama :)
# Create chart object and specify the properties of the chart my $chart = Chart::Gnuplot->new( output => "fig/simple.png", title => "Simple testing", xlabel => "My x-axis label", ylabel => "My y-axis label", .... gnuplot => "dramaqueen.exe", );

    Bless you brother, I completely missed the gnuplot => "path to exe" option. However, also in this case I get an Invalid Parameter - 90 error message.

      Based on your other reply, it seems that you are mixing "/" and "\" directory separators in your chart's file name. Try not to... :-)

      the file name should either be
      \tmp\NTEVfipQVM\plot or
      /tmp/NTEVfipQVM/plot but not
      \tmp\NTEVfipQVM/plot ...

      []s, HTH, Massa (κς,πμ,πλ)

        It's not me mixing up "/" and "\", judge for yourself:

        use strict; use warnings; use Chart::Gnuplot; my $chart = Chart::Gnuplot->new( output => "c:/tmp/test.png", title => "Simple testing", xlabel => "My x-axis label", ylabel => "My y-axis label", gnuplot => "C:/gnuplot/binaries/wgnuplot.exe", ); my $dataSet = Chart::Gnuplot::DataSet->new( func => "sin(x)" ); $chart->plot2d($dataSet); print "Done...\n";

        Resulting in the familiar error message;-)

      However, also in this case I get an Invalid Parameter - 90 error message

      I'm starting to get the feeling that the gnuplot executable and wgnuplot.exe must take different arguments.

      Cheers,

      Hmm, works for me :/

      I used gp424win32.zip from here.

      I also removed DIR => '/tmp' from Gnuplot.pm, because I like my existing temp directory just fine.

        Hmm, I use exactly the same stuff. I think I redo the installation of both and try again. What Perl and what version of Chart::Gnuplot do you use?

        Cheers
        dHarry

[ambrus]: Corion: I think I parsed a HTTP header from a string with LWP once. You can definitely use that to create a HTTP message too. The problme is
[ambrus]: that if you do that, you'd have to find where each HTTP response ends, which is nontrivial if you want persistent connections (essential for performance if you have small requests).
[Corion]: ambrus: Yes, ideally an API that I feed the incoming data piece by piece and that I can ask "is that response done" and "what should I do next" and "please construct the appropriate redirect for me"
[Corion]: ambrus: Yes, ideally the module would do all that nasty stuff for me and give me a way to ask it what the current situation is
[ambrus]: Corion: you could also consider using some wrapper over the multi interface of curl, I think Net::Curl might be a good one, since implementing enough of what it expects from the event loop might be easier than a full AnyEvent interface.
[ambrus]: Corion: you could also consider using IO::Async and its POE driver and some HTTP module for it, but I don't know if that would solve your problems with AnyEvent+POE
[ambrus]: Corion: wait, you didn't say POE. You said Prima, let me look up what that is.
[ambrus]: Corion: have you considered just writing an AnyEvent integration for that thing?
[ambrus]: Or perhaps pushing schmorp to write one?
[ambrus]: Also, searching for an existing one on CPAN obviously
