HTML::BarGraph -------------- A Perl module which creates bar graphics for one or more datasets, using plain HTML and, optionally, "stretched" pixel images. Features -------- - it can display more than one data set on the same graphic - one can change the direction of the bars (vertical, horizontal) by simply changing one parameter - when used in plain HTML mode, the graphic (and the module) is completely independent - it doesn't require any graphic or graphic library - when used in plain HTML mode, the graphic is entirely included in the page, so by saving the webpage, the whole graphic is saved with it - highly customizable - graphics for web polls and such simple data sets can be quickly created, without the overhead implied by "on the fly" graphic generation Screenshots ;) -------------- A sample of what the module can do is included in the distribution (sample.html). The source of this HTML file contains the parameters that each graph was generated from. Install ------- HTML::BarGraph is plain Perl, and so far has no dependencies, so install it like: perl Makefile.PL make make test make install Pixels ------ Before using the module with 'bartype' set to 'pixel', you need to install the various color pixels which will be used to draw the bars. As a start, you can use the pixels provided in the module's distribution (pixels/*.png). You need to install these manually, since there's no way to know the location where you want them to live.
