Reality Inverted

Reuters graph implies the opposite of what’s really happening

Graphics — especially simple graphics— should take into account reader’s expectations, not require careful study to correctly interpret their meaning. This Reuters graph inverts the vertical axis, creating the impression that deaths went down when in fact deaths went up. This graph runs counter to a well established convention that y-values increase from the bottom to the top of a graph. Breaking convention produces a graph that seriously misleads. A redrawn version of the graph instantly delivers the correct impression.

The Power of Showing Not Telling

Trefis graphically presents its analysis and invites you to tweak it

Trefis graphically presents the components of its forecast, showing how they add up. Clicking on a component drills down to display the assumptions. That alone would be noteworthy, but Trefis goes one step further: the various trend lines are easily adjustable, allowing the viewer to both enter their own expectations and explore different scenarios. Instead of taking a forecast at face value, this permits every customer to dig deeper into the analysis and to develop their own personal forecast, based on their understanding and beliefs.

Edward Tufte’s ‘Slopegraphs’

July 17, 2011 1 comment

In his 1983 book The Visual Display of Quantitative Information, Edward R. Tufte displayed a new type of data graphic. He was completely ignored.

Last month Tufte reintroduced the graph to the world, now christened as “Slopegraphs.” “Slopegraphs compare changes over time for a list of nouns located on an ordinal or interval scale.”

Charlie Park followed up with an extensive examination. “Any time you’d use a line chart to show a progression of univariate data among multiple actors over time, you might have a good candidate for a slopegraph.”

Financial Times’ iPad Dashboard looks and acts like an iPad app, but it is actually an HTML5 web page.

The advantage for the publisher is not having to endure Apple’s approval process, not having to pay Apple a 30% commission, and the ability to market content outside of Apple’s overcrowded App Store.

It is also much less costly to develop a Web page than to program a complicated app from scratch.

HTML5 Web pages also have the potential for reaching a wider audience. An app will be tied to a single type of tablet computer. An HTML5 Web page will be instantly viewable on any device that supports the new HTML5 standard.

Thanks to the capabilities of the new HTML5 standard, FT’s presentation can be made with few compromises. A large amount of critical and almost up to date (delayed 20-minutes) data is made available in a single convenient dashboard.

This page of Market Data is navigated using standard iPad finger gestures. The various information panels are interactive, enabling the reader to scroll through the data, focusing on what interests them.
