A few years back I wrote an app for tracking the various numbers and values that are prevalent in a datacenter. This app tracked the vitals of all kinds of doodads. It was a glorified visualization tool. I used various bits from CPAN but eventually got fed up and decided that I [...]
Rather than clutter up my personal blog with dribble about charts, I’ve created a new home for Chart::Clicker. I’ve also puncuated this with the release of 0.2.3.
Now I can’t use Clicker as a crutch for posting here…
I’ve been avoiding writing two pieces of Chart::Clicker: the legend and the axis and it’s labels. I don’t know why. Perhaps they just aren’t as fun as the renderers.
Tonight I took a crack at it. The above example admittedly doesn’t look like much but it’s actually a lot of progress. There [...]
I have now exposed opacity of the Area renderer, plus added the ‘fade’ option as well. I only exposed these new hooks (as well as an option to pass a Stroke) in Area. The other renderers, being red-headed step-children, will have to wait. You can now generate things like this:
chart-clicker-0.2.2 The example charts [...]
Cairo.
GD was giving me some trouble and the frustrations got my eyes wandering. As I pondered graphic libraries I recalled Gnome’s noise concerning Cairo, so I went to check it out. I was impressed with it’s capabilities. I was pleasantly suprised to find Cairo.pm on CPAN, so here we are. All the Renderers [...]
I’m getting close to releasing this thing on CPAN, I think. I learned the ropes with the recent release of Data::Stack (which needs some more work to be good) and know how to use PAUSE now.
What’s new? I switched to using Class::Accessor for all the classes for convenience then added Point, Insets, Border [...]
Tonight I added a Color class and setup Chart::Decoration::Marker to use it. I also added a color to the Decoration::Grid so that the Markers it generates can have a special color.
chart-0.0.4 - The examples have been updated, but little is different.
$chart->plot->()->grid()->color(new Chart::Color(200, 200, 200, 0));
This raises an interesting problem for me. Chart is [...]
Before I leave to stay at Nicole’s for the weekend I have to release 0.0.3. I couldn’t tolerate how ugly the grid code was. This release has a proper grid and all the renderers honor it. You can change the ticks with:
$chart->plot()->grid()->domain_ticks($x); $chart->plot()->grid()->range_ticks($x);
You can look at the examples to see the result.
I’ve still not settled on a name.
This change yields nothing to the end user, unless you happen to be using an area chart. The changes are all internal so there is also no code sample to show. The changes should allow me to flesh out new features though. I’ve spent the last few nights [...]
I’ve been hacking away on a charting package the last week or two and despite the fact that I’m not very happy with it I’m going to let it loose.
chart-0.0.1.tar.bz2 I spent a lot of time with Chart packages a few years back when at the last $job. None of them left me feeling satisfied [...]
