A recent release of JDeveloper 22.214.171.124.0 has brought to us the following new Data Visualization features:
New Component: NBox
NBox is used to visualize and compare data across two dimensions. It is commonly used to visualize and compare employee performance. New design time for NBox is also now available.
New Chart Types
In addition to the new charting solution that was previously introduced in 12.1.3, in 126.96.36.199 we are introducing the new Funnel chart to replace the Funnel graph, and polar coordinate system is also now supported by several chart types.
Funnel charts are used to visually represents data related to steps in a process. The steps appear as vertical slices across a vertical or horizontal cone-shaped section. As the actual value for a given step or slice approaches the quota for that slice, the slice fills. Typically, a funnel chart requires actual values and target values against a stage value, which might be time. For example, use the funnel chart to watch a process where the different sections of the funnel represent different stages in the sales cycle.
Polar coordinate system: Several Chart types now support a new
coordinateSystem attribute that specifies if the chart uses Cartesian or Polar coordinates.
A polar chart has a radial y-axis and a tangential x-axis. Polar coordinate system can be used for bar, line, area, combination, scatter, and bubble charts. Polygonal grid shape (commonly known as "radar") is supported for polar line and area charts.
Polar charts are recommended for directional data. (e.g. air drag vs. boat angle)
Polar charts are also recommended for categorical data where all categories are equally important. (e.g performance appraisal categories)
Below are examples of Polar Bar and Polar Line Charts. Polar line has a polygonal shape grid also known as radar chart:
Polar Area chart:
Polar Scatter and Bubble Charts:
Thematic Map Backport
Previously only available in 11.1.2.x and 12.1.3 releases, Thematic map has now also been backported to 188.8.131.52.
Design Time Features
Design time for NBox, Diagram, Thematic Map and the new Charts is now available in JDeveloper.
NBox design time:
Diagram design time:
Detailed step-by-step instructions on using the design time are available in the Oracle Fusion Developer's Guide chapter on Creating Databound Data Visualization Components.
