Gnuplot is very slow, replace it with plplot

[Jari Häkkinen]

Needed for #75 and #279

Depends on plplot bug ​http://sourceforge.net/tracker/?func=detail&aid=2901388&group_id=2915&atid=102915 Until the plplot issue is resolved you must download plplot 5.9.5 and patch the plstream destructor manually before compiling and installing plplot.

Gnuplot replaced with plplot, the rest of the tickets are split into #402, #403, #404, and #405

[Jari Häkkinen]

There is no API for the current gnuplot and no plans to create one exist

[Peter Johansson]

What about GNU libplot?

​http://www.gnu.org/software/plotutils/

There is clearly an API for C/C++

[Peter Johansson]

added relataion with #75

[Jari Häkkinen]

This change will be implemented in branch source:branches/replacing_gnuplot

Look at the example page, ​http://plplot.sourceforge.net/examples.php, click on one of the sample plots and select your favourite language in the tab, copy&paste! That is it, I am going for plplot and I am starting tomorrow so there is some time to try to convince me for something else.

[Peter Johansson]

Found that plplot is included in Fedora 9, the examples look good, and it is licensed under LGPL, so go ahead.

[Jari Häkkinen]

(In [786]) Addresses #97. Removed gnuplot checks in configure.ac and added checks for PLplot. Updated README.

[Jari Häkkinen]

(In [787]) Addresses #97. Removed gnuplot tests.

[Jari Häkkinen]

(In [788]) Addresses #97. Removed gnuplot files, added Graph class.

[Jari Häkkinen]

(In [789]) Addresses #97. Removed GnuplotFE dependency in File.cc

[Peter Johansson]

I think it should be possible to build and run svndigest without the plot machinery (plplot). 1) svndigest --copyright is still useful 2) Possibly we should even allow reports without images (just a [plot] instead).

[Jari Häkkinen]

(In [855]) Addresses #97. One summary plot is generated with plplot ... much more to do.

[Jari Häkkinen]

(In [858]) Addresses #97. Merging non-gnuplot plot generation code. Gnuplot traces left and lot of work before publication quality plots are generated.

[Jari Häkkinen]

(In [859]) Addresses #97. Improvements to summary plot.

[Jari Häkkinen]

(In [863]) Addresses #97. Fixed background, added doxygen and other comments.

[Jari Häkkinen]

(In [864]) Addresses #97. All plots generated. Now its time to go for publication quality plots.

comment on the issue at plplot tracker

[Jari Häkkinen]

I'll look into that. My suggested patch works for us since we never have more than one stream open at any time. However, we should of course use the official fix. I'll create a patch for released plplot 5.9.5 and post it somewhere. I prefer not to live on plplot trunk.

[Jari Häkkinen]

I attached ​plstream.cc and ​plstream.h to this ticket. These files are copied from the plplot subversion trunk revision 10626. It was too hard to create a patch due to many avoidable changes in the files (space, change of comment style, moves of '{' from one line to another) so I attached the complete files. I tested them with svndigest and make check passes and plots are generated.

(In [917]) Addresses #97. Background white and transparent.

[Jari Häkkinen]

(In [945]) Addresses #97. This branch was merged into the trunk and is not needed anymore.

[Jari Häkkinen]

(In [946]) Fixes #97. Well, gnuplot is now removed and sub task are defined in other tickets.
