PGPLOT Graphics Subroutine Library

PSRCHIVE uses the PGPLOT Graphics Subroutine Library to produce publication quality plots in a variety of styles. PGPLOT is available from T. J. Pearson.

Automatic Installation

The PSRCHIVE configure script produces a package installation script that can be used to automatically install PGPLOT; e.g. 
./configure
packages/pgplot.csh
Upon completion, the installation script will provide instructions on how to set the $PGPLOT_DIR and $PGPLOT_FONT environment variables. After setting these variables, re-run the configure script to enable PGPLOT functionality.

Manual Download/Installation

Download PGPLOT as described in step one.

Unpack the zipped tarfile somewhere temporary, make an installation directory, and run makemake with the appropriate arguments. For example, assuming the installation directory is $HOME/pgplot on a Linux system with the GNU compiler collection: 

cd /tmp
gunzip -c $HOME/pgplot5.2.tar.gz  | tar xvf -
mkdir $HOME/pgplot
cp pgplot/drivers.list $HOME/pgplot
Then edit the file $HOME/pgplot/drivers.list, removing the exclamation marks from in front of the drivers that you wish to enable.

We recommend at least all of the PSDRIV (Postscript) and XWDRIV (X Window) drivers and, optionally, the PNDRIV (Portable Network Graphics) drivers. Note that, if you enable PNDRIV, you will have to edit the makemake script that comes with PGPLOT. Simply remove the following line: 

pndriv.o : ./png.h ./pngconf.h ./zlib.h ./zconf.h

If you will want to use --enable-shared while running configure, you need to apply a patch to the makemake script to enable shared pgplot libraries. To do this, run the following commands: 

cd /tmp/pgplot
patch < /usr/local/src/psrchive/packages/makemake.sharedcpg.patch
where we assumed the sources of psrchive are located in /usr/local/src .

When finished editing, run makemake as follows: 

cd $HOME/pgplot
/tmp/pgplot/makemake /tmp/pgplot linux g77_gcc_aout

If only gfortran is installed on your system, then edit the makefile produced by makemake, change FCOMPL appropriately and remove the -u flag from FFLAGC.

To ensure that everything is made (mostly important on OS X): 

make
make cpg
make pgxwin_server
make grfont.dat
Finally, you will have to add the following to your .cshrc file: 
setenv PGPLOT_DIR $HOME/pgplot
setenv PGPLOT_FONT $PGPLOT_DIR/grfont.dat

if ( $?LD_LIBRARY_PATH ) then
  setenv LD_LIBRARY_PATH ${LD_LIBRARY_PATH}:$PGPLOT_DIR
else
  setenv LD_LIBRARY_PATH $PGPLOT_DIR
endif
