Visualization Visualization Histogram
This document captures the visualization requirements for a histogram plot in the Hub (HQuery).
For these requirements, we will re-use the question from IT2. In IT2, we generated a text report on most frequent classes of medications. In this sprint, we will develop a graphical visualization for the same query.
- A histogram plot showing ranked order of most common items.
- Ability to set an arbitrary number of elements
- Can choose most frequent or least frequent
- Can choose to visualize vertical or horizontal histogram (depends on data needs)
- Can export the image.
- Displays labels for each category
In order to assess the most common prescribed classes of medications
The Network Question Manager should be able to
Select an HQuery visualization to display the results of the
frequent prescribing query as a horizontal histogram that
shows the top 20 classes of medications by prescription frequency.
In order to share findings visually with colleagues
The Network Question Manager should be able to
Export an image of the histogram visualization.
