How best to show journal usage and publications, over timeI commonly analyze packages of scientific journals, and we often want to know if there are titles that are not being used that we can stop subscribing to. I usually graph usage (download count) vs. publications (how many papers did our authors publish in that journal) for a given year. Generally, high use journals will have more publications, though not always.
Creating this graph every year gives me multiple independent snapshots of each journal's performance. But how can I best compare these yearly graphs to each other? Is this low (or high) performing journal from this year one that is a common underachiever, or was this just an outlier year? The packages usually contain anywhere from 70-150 individual journal titles, so the plots are fairly cluttered already, which is why I am reluctant to color-code by year and symbol-code by title.
What are some recommendations to track a journal title over time, while also seeing the bigger picture?
AnalyticsGraphicsRe: How best to show journal usage and publications, over timeThanks, Ian. I don't know about local data filters. I found a JMP help page that walks through an example and will go through that today.

Re: How best to show journal usage and publications, over timeRegarding "But how can I best compare these yearly graphs to each other?", I would generally advocate using a local data filter, possibly with animation, with your favourite graph types. In this case I would define 'Year' to have Modelling Type 'Ordinal' and filter by that. You may also need to 'Lock Scales' of graphs to facilitate the comparison.
