5svnstat uses a C++ interface to Gnuplot written by Rajarshi Guha. The
6interface is integrated in the svnstat code with some modifications
7(see below). The original code used for svnstat can be found in
8directory ./gnuplot_i++.
10Rajarshi Guha's "A C++ Interface to Gnuplot" can be found through
11 . The C++ interface is based on "gnuplot
12interfaces in ANSI C" written by Nicolas Devillard. The C implemention
13is available through .
15Changes made to the C++ Gnuplot interface files (gnuplot_i.hpp and
18i) Changed filename gnuplot_i.hpp to gnuplot_i.h, and consequently
19   changed #include directive in
21ii) Encapsulated the interface into namespace theplu::svnstat.
23iii) Added $Id: README 26 2006-01-05 01:36:42Z jari $ tags in both files.
25iv) Changed the initial #ifndef/#define idiom to avoid potential
26   clash with the original implementation.
28v) gnuplot_i.h: Removed the 'using namespace std;' statement, since we
29   don't want to expose the std namespace to everyone using the
30   Gnuplot interface. This triggered subsequent changes to code lines
31   with string and vector<> usage.
33vi) Resolved signed/unsigned compiler warnings in on
34   lines 235, 278, 418, and 482
36vii) Changed order of code in Gnuplot destructor, now
37   the pipe is closed first. I have not done a full scale
38   investigation on why this is needed, but on MacOSX the files are
39   removed before gnuplot plots data when the original code order is
40   kept.
