*** THIS MODULE IS NOW DEPRECATED -- USE GD::Graph INSTEAD *** This is PNGgraph 1.21, a package to generate PNG charts, using Lincoln Stein's GD.pm. It's a wrapper around GD::Graph, provided for backward compatibility with existing Chart::PNGgraph scripts only. This package is deprecated. I would recommend that you use GD::Graph directly. INSTALLATION needed to install (also see TESTED PLATFORMS): perl 5.005 (5.004 might work) GD > 1.18 GD::Graph GDTextUtils (for GD::Graph) to install: perl Makefile.PL make make install to see some samples: cd samples make That should generate a set of pngs, which you can view using the HTML pages in the same directory (or whichever other way pleases you). IMPORTANT CHANGE SINCE VERSION 1.15 Chart::PNGgraph no longer contains any of the code to generate charts. Instead it has become a wrapper around GD::Graph. The main reason for this is that the two code bases for GIFgraph and Chart::PNGgraph have been merged back together, and will be maintained in a single spot again. Blame Unisys and their childishness over the LZW patent for all this. GD VERSIONS If you want to use a GD version 1.20 or up, you will need to have something installed that can do an on-the-fly conversion of PNG to GIF. I can't recommend that you do this way, but there may be some obscure and odd reason that you want to produce PNG images, but have to use an old GD. If you have to: I recommend that you use Image::Magick, since that is what the Chart::PNGgraph module has been setup to use. If you don't want to, or can't install Image::Magick, you will have to edit the file Chart/PNGgraph/Convert.pm to provide a different sub gif2png. TESTED PLATFORMS None. In fact the tests have been removed as a reminder that this package now exists solely for backward compatibility. If your existing scripts work with this module, then that is all that's important at this stage.
