------------------------------------------------------------------------ Chart version 0.99b ------------------------------------------------------------------------ This is mainly a bugfix release for 0.99a. The primary changes are a fix for user-defined dataset colors, and adding a no_cache option for http headers. no_cache is currently experimental, because, unfortunately, Netscape 4.5 breaks with POST while using this. I'm looking into workarounds, and if anyone has ideas, feel free to mail me: ninjaz@webexpress.com Also, look for new and improved Pie charts with the next release! Enjoy. :) ---------- 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 ------- CHANGES ------- 0.99a - 0.99b: Fixed left legend in composite charts Fixed no color problem when using composite charts w/ no legend Fixed color handling for datasets Added option for http header Pragma: no-cache Netscape 4.5 has a bug that breaks it, but it works with other browsers. Any ideas for a workaround? 0.99 - 0.99a: Added use of undef() values to represent 'no data' for line breaks Added ylabel*_color options Added x_grid_lines, y_grid_lines & y2_grid_lines , and color options for each Cache disabling in cgi header: Reiner Nippes Restored grid_lines option: Heinz-Guenter Kontny Fixed a typo that broke imagemap data storage in Lines charts 0.94 - 0.99: Modified the 'title' option to correctly process newlines Deprecated the 'subtitle' option, will remove it in next release Changed the API for specifying colors Added support for printing to file handles Added Chart::Composite Added 'spaced_bars' to make it easy to differentiate the bars Added 'grey_background' to make plot background grey Added support for negative values in the datasets Added methods to remember and dump imagemap pixel information Included rgb.txt with distribution for WinXX users 0.93 - 0.94: Moved the legend down to be flush with the chart Fixed the long decimal y-tick label problem Fixed (for the last time, hopefully) the pre-5.004 compilation problem Fixed handling of undefined data points Added more colors for the default data colors Added the transparent gif option Added the option for user-specified colors Added the grid_lines option 0.92 - 0.93: Fixed the sort problem Fixed the y-axis label centering problem Fixed pre-5.004 compilation problem Added StackedBars charts ------ MAINTAINER ------ Peter Clark (ninjaz@webexpress.com) --------- COPYRIGHT --------- Copyright(c) 1997-1998 David Bonner, 1999 Peter Clark.
