Awesome! Even though the figures aren't very meaningful with my context, they seem very Tuftian.

Speaking of, the only thing that makes me happier than Tufte is having a visualization I generated in Matlab at work when debugging a difficult networking problem praised by a reference to Tufte. :)

I hope to make them more Tuftian, perhaps by making the marks more meaningful on their own. Right now they are not very meaningful outside of the interactive context, which is poor information design.

Has anybody read book 4 yet? Is it awesome?

How are things in FL?

And what is the problem and visualization you produced?

Exciting!

We have a complicated radio that loses a very small amount of frames in part of the system that's effectively a black box. I was looking for correlations to the loss over time and eventually was able to build a graphical representation of the timing and data flow that makes patterns in the loss really easy to see. The first few causes of the problem have fallen away rather easily and were visible as stripes in time and frequency, but the more complicated ones have taken some extra effort. The novelty came from thinning the data down and presenting the schedules (which change a lot) without hiding any of the main event, which is the frame loss. I also have kind of a neat chart that shows what the probability distribution looks like when various classes of error are considered alone that makes good use of whatever he calls it when you can visually compare complex patterns without needing as much context for successive figures. All of these in the time domain are plotted with a few things in the background that show overall traffic ( ... )
