Please refer to https://osrt.opensuse.org/web/origin-manager/#openSUSE:Leap:15.2 for origin information https://download.opensuse.org/distribution/leap/15.2/repo/oss/ perl-Chart Series of Charting Modules These man-pages give you the most important information about Chart. There is also a complete documentation (Documentation.pdf) within the Chart package. Look at it to get more information. This module is an attempt to build a general purpose graphing module that is easily modified and expanded. I borrowed most of the API from Martien Verbruggen's GIFgraph module. I liked most of GIFgraph, but I thought it was to difficult to modify, and it was missing a few things that I needed, most notably legends. So I decided to write a new module from scratch, and I've designed it from the bottom up to be easy to modify. Like GIFgraph, Chart uses Lincoln Stein's GD module for all of its graphics primitives calls.
