Statistical Graphics and more

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 […]

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 […]

Thanks to the data provided by the USGS, we can take a look at all earthquakes since 1973, which cover almost the last 40 years of earthquake activity worldwide. 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 […]

The new version (1.2) of Mondrian adds the following (significant) features: Scatterplotsmoother now includes “principle curves“, which are one of the nonlinear generalizations of principal components. All smoothers can be plotted for subgroups, which have a color assigned, “smoother by colors“. The color scheme has been refined once again, to make use of colors as […]

Pretty hard to get any attention while Steve is presenting the iPad 😉 , but nonetheless I like to point to the new version 1.1 of Mondrian. 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 […]

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 […]
