CFUnited Demo – Axiis Treemaps
Yesterday Tom Gonzalez and I gave a presentation on Axiis at CFUnited. After Tom reviewed the concepts behind the framework, I demonstrated how to build a custom visualization. The resulting application showed a squarified treemap representing the make up of Axiis, Degrafa, Flex, and the Flex Data Visualization framework. I cleaned up the code from [...]

Axiis Video Tutorial
An experimental alpha release of Axiis has been available since 360|Flex Indy. I put together this screencast to help people get up and running with the framework. We’ve gotten some feedback from a few people already, and some users have already told us about the awesome stuff they’re making. Remember during Tom’s presentation when he [...]

Axiis – A different kind of data visualization framework
Last week Tom Gonzalez wrote a blog post announcing Axiis, the open-source data visualization framework we’ve been developing. Tom goes into a good deal of depth about how the system works, so I won’t rehash all those specifics here. I just wanted to share my take on what Axiis is meant to do at a [...]

Hit detection on graphics primitives: Speeding up the Parallel Coordinates Plot
In my last post I mentioned that I had rewritten the Parallel Coordinates Plot to achieve a pretty drastic speed up. Before I get into the graphics hit detection trick at the heart of the performance boost, I’d like to explain the problem with the original implementation. The main thing that dragged down the first [...]

Visualizing the 2008 NFL Season
Super Bowl XLIII is less than two weeks away, so it feels like an appropriate time to look back at the statistics that were so diligently recorded during this past football season. I’ve put together a comparison matrix based on data from pro-football-reference.com. For first time visitors, a comparison matrix processes multidimensional statistics, looking for [...]

The ComparisonMatrix component… or Playboy Playmates and the Economy
One of the challenges of information visualization is to present data in a way that allows the interesting patterns to rise to above the noise. The ComparisonMatrix allows users to quickly assess where these patterns are so they can make an informed decision about where to start exploring. To do this, the ComparisonMatrix breaks a [...]

Adding hints to Flex 3 MXML tags
ColdFusion tags can be annotated with the hint attribute, effectively creating a surrogate for single line comments. This is something I’ve wanted to be able to do in MXML for a while, and I’m glad to see the Gumbo specs include this feature in the form of private attributes. If you can’t wait for Flex [...]
Parallel Coordinates Plot in Flex
I spent the past few weekends writing a parallel coordinates plot. For the uninitiated, parallel coordinates plots are used to show the relationships between items in a multidimensional dataset. Three dimensional data points can be difficult enough to visualize on a two dimensional screen, and when you throw even more dimensions into the problem, things [...]
