Horizon Graphs

Stephen Few writes about horizon graphs for time series designed for visualization and comparison: " ... horizon graphs can meaningfully display 50 or so full sets of time-series values on a single screen or page in a way that supports comparisons among them ... " . Had not heard this kind of view described as a 'horizon graph' before. The example above gives a side-by-side example of stock comparisons, one per row. The image is here is too small, you can see it in detail through the link, but the resulting out-of-focus view is revealing as well.
