The trend analytics page displays histograms, where the evolution or trend of a numeric property in time is shown. This is the same information as what is shown on the timeline on the visual analytics page.
However, compared to the visual analytics timeline, the trend analytics page:
Makes it easy to compare the trend in different regions against each other
Makes it easy to compare two time periods against each other, and spotting the differences
Allows to change the X-axis of the histogram to group by day or hour instead of showing the evolution in time
Example use-cases for the trend analytics page include:
Comparing footfall traffic in different stores
Comparing increase/decrease of business of different terminals in a port
