Chart::PNGgraph is a perl5 module to create and display PNG output for a graph. The following classes for graphs with axes are defined: Chart::PNGgraph::lines Create a line chart. Chart::PNGgraph::bars Create a bar chart. Chart::PNGgraph::points Create an chart, displaying the data as points. Chart::PNGgraph::linespoints Combination of lines and points. Chart::PNGgraph::area Create a graph, representing the data as areas under a line. Chart::PNGgraph::mixed Create a mixed type graph, any combination of the above. At the moment this is fairly limited. Some of the options that can be used with some of the individual graph types won't work very well. Multiple bar graphs in a mixed graph won't display very nicely. Additional types: Chart::PNGgraph::pie Create a pie chart. WWW: http://search.cpan.org/dist/Chart-PNGgraph
