I've been watching this project and it keeps getting better. The prettiest plug-and-play data graphs on CPAN!
The docs are good but missing information on a number of the subtle tweaks. For example, I had troubles figuring out how to adjust the width of the line in a line chart (the default width is far too thick when there are thousands of points on the graph). It turns out to be easy enough ($ctx->renderer->brush->width(1)) but I couldn't find it in any the docs or tutorial. I ended up finding it in the examples, which are a fabulous resource:
Yet another charting/graphing module, using yet another graphics engine.
Chart::Clicker is based on the Cario graphics library (cairographics.org), and as used by this module, produces some charts with beautifully-blended alpha layers and gradients.
Documentation is described as largely 'todo' since this young project is still in a state of alpha flux, but the interface looks sensible. Youth probably accounts for the lack of chart types currently available.
It would be nice to see some integration between ::Clicker and GD::Graph::Data, perhaps, but that is picky.
Overall, Clicker is certainly worth keeping an eye on as a replacement for quick-fix graphing currently provided by GD::Graph. It will not become as popular, though, until someone builds a Win32 PPD that includes Cairo!
Being a young project, Chart::Clicker does not offer yet the same variety of charts produced by GD::Graph*, but the quality of the output is already far superior, thanks to the rendering library used (Cairo -- I welcome this project mainly because of this, being Cairo one of the best graphics libraries available, yet used only by few CPAN graphics distros).
To the author: please, keep the examples there ;-)
And thank you for your valuable work.
