------------------------------------------------------------------------ Chart version 0.99c-pre3 ------------------------------------------------------------------------ **** WARNING **** This version of chart has replaced gif support with png support due to the Unisys patent problems. This is the first png-enabled release. This version has fixed the x-axis placement bug in 0.99b, and all existing functionality, save for gif creation should be stable. New (and incomplete) area pattern functionality is currently Mountain. See t/mountain.t for calling details. Please send comments/patches/etc to ninjaz@webexpress.com (read: the current pattern API is subject to change) ---------- There are some very nice additions this iteration. Specifically, black & white readability has been extremely improved by custom points for LinesPoints & Points, and patterns are now optional. Mountain Charts have also been added. ---------- INSTALLING ---------- The usual. perl Makefile.PL make make test make install This should install to your site_perl directory. The test scripts also put samples of the different charts in the samples/ directory. ------------- PREREQUISITES ------------- Lincoln Stein's GD module version 1.20 or higher. ------- CHANGES ------- 0.99b - 0.99c-pre3: James F Miner <jfm@winternet.com>: Added Mountain chart type Added Patterns.
