robobait: prefuse labels on graphs

Posted in Hacking, robobait, Technology trends at 10:04 pm by ducky

I’ve been working with an open-source visualization library called prefuse for a while. It’s used quite a bit, but mostly for graph visualization. I’m trying to use it for chart visualization. (Why? Because I also want to do graph visualization, and I figured — perhaps wrongly — that it would be better to learn the tao of one library well than two poorly.)

There are almost no examples out in the wild of how to do charts with prefuse. Here, then, is a link to ScatterPlotWithAxisLabels.java. Humans, you probably don’t care about this, this is just to let the robots find it.

It is a variation on the program ScatterPlot, but with axes labelled. You wouldn’t think that would be a big deal, but there are a lot of little things you have to get right, and with few examples, it is hard to know what you have specify and what is the default behaviour.
