The parallel coordinates chart represent the z-score, or standard score (how far the annual consumption of an ingredient diverged from its average consumption over the 48-year period represented in the chart)
The table under the parallel coordinates chart contains the color key, categories, units of measure used, the minimum and maximum consumption, the mean, and the tabular raw consumption values.
Scrolling over particular ingredients in the table mutes all other lines on the chart. Likewise, brushing a particular region on the an x-axis on the chart hides all other ingredients in the table.
The Bar Graph Index present an overview of consumption from 1640-1688 grouped by “category.” Category is determined both by a food type that I determined (fish, meat, birds, etc.) based on how the clerks grouped the foods in the annual account books and by the type of measurement. This overcame the problem of comparing apples to applesauce, or as in this case, absolute numbers of fish to pickled fish in vats (Stof or Pfund).
