I noticed that our communications office created a one-off visual ring chart for our Match Day communications and wanted to recreate that fast, at-a-glance readability in Oracle Analytics with a custom visualization focused on progress and breakdowns. I view this as a great method for conveying percentages across categories at the top or side of a dashboard with additional detail presented in separate visuals.
Which dataset did you use?
An anonymized outcomes dataset with one row per category (for example: specialty, program, or cohort segment), including a label, a percentage/progress measure, and an optional color field.
How did you analyze or prepare the data?
- Standardized values to a 0–100 percentage scale (including 0–1 ratio conversion where needed).
- Cleaned nulls/outliers and capped values to valid percent bounds.
- Added sorting and Top N controls for focused comparisons.
- Built a custom Match Rings Oracle Analytics plugin with:
- Responsive layout
- Vertical/Horizontal orientation toggle
- Palette support + custom accent option
- Accurate centered in-ring percentages
- Sweep animation to target percentage
- Sweep speed + stagger controls
- Reduced-motion mode
- Value formatting options
- Threshold color modes
- Wired subtitle, ring size, and row spacing controls
Who is the intended audience for your visualization?
Medical school leadership, program directors, advising teams, and operations/communications users who need quick status insight without scanning dense tables.
What is your visualization about, and what question or problem does it address?
This Match Rings view provides instant understanding of progress across categories. It helps answer:
- Which areas are on track or behind?
- Where are the largest gaps?
- What does the overall distribution look like at a glance?
Did you use any Oracle Analytics AI features when building your visualization (e.g., AI Assistant)?
No. Data prep used standard Oracle Analytics expressions/filters, and the visualization is a custom Oracle Analytics plugin.
