Making Movies

Making Movies is not only the name of an album by Dire Straits, but also the invitation of the ASA Statistical Graphics Section to enter the video competition. You might find the link a bit late (where I can’t dispute, but most creatives prefer to deliver “last minute”, so there is probably still some time […]

Fuel Economy: Multiple Scatterplot Smoother

I once in a while stop by at the JMP blog, and I was surprised to find tools and techniques implemented in JMP, which I built into Mondrian in the early 2000s. In the post “Visualization of fuel economy vs. performance“, we find a showcase of using multiple smoothers in a scatterplot for acceleration versus fuel […]

Japan Earthquake: An Exploratory View

Let’s first take a look at the yearly development of the earthquake activity overall: The apparent increase in the last 10 years is striking – though […]

Can you spot the Error?

Here are the most important new features: Load data directly from R workspace files New color schemes Compatible with Java 6 on all platforms Very many bug fixes […]

Parallel Sets vs. Mosaic Plots (Take I)

Robert has released the wonderful parallel sets tool in version 2. It is JAVA, it is interactive – so what do we want more! As I spent some time thinking about the display of categorical data and creating tools for their visualization myself, I thought it would be a great idea to compare the parallel […]
