If the new window is stuck at "Waiting for http://cityscape..." and you used Bungee View before February 2007, go to the Java control panel, find Temporary Internet Files, and click the Delete Files button. This is because cityscape is now a different computer.
For each metadata category, vertical bars show the distribution of images in the collection that match your query. In the screenshot above, the query is for images of 12th century artifacts. The row of bars labeled "Material" shows the resulting distribution for Cloth, Glass, Parchment, and Stone. Wide bars represent Materials that appear in many images in the collections. Tall bars represent Materials a large fraction of which appear in images that match the query. For instance, 30% of Stone artifacts are from the 12th century, while only 4% of Glass artifacts are. The curve superimposed on the percent labels shows the non-linear scale. It distorts the bar heights so that the average value (17% for Material) is half as high as 100%. The blue-gray background indicates this average value.
In data-mining terms, there is a positive association between 12th century and Stone, while there is a negative association between 12th century and Glass. Any bar that extends above the blue-gray background represents a positive association, and vice versa. The bar color indicates whether the association is statistically significant. Gray bars stand for values that are not significantly associated with the query. Muted green bars are positive significant associations (at a significance level of one in ten thousand, using a Chi Squared Test, or for small expected values a Fisher Exact Test). Orange bars are negative significant associations. Both the Stone association and the Glass association are significant. Saturated green and red bars (such as 12th century) are for values that are part of the query.
