What happens to the dashboard numbers when the Current Year filter is changed?

Conditions

• The dashboard is actively displaying the ROAD ACCIDENT DASHBOARD.
• The user interacts with the Current Year dropdown menu.

Reasoning, step by step

1. Start with the dashboard set to a specific year (e.g., 2022) and note the visible totals.
2. Open the Current Year dropdown and select a different year (e.g., 2021).
3. Observe the immediate, coordinated update of the KPI tiles, monthly trend lines, and donut-chart centers.
4. Return the filter to the original year to verify that the values revert accordingly.

Example

With Current Year = 2022, the dashboard shows Total Accidents 141,200 and Total Casualties 191,681. After selecting 2021, the same tiles update to 176,727 and 241,177, and the donut centers change to 5.3K.

Common misconceptions

• Assuming the dashboard computes these totals from the underlying dataset on screen; the clip only shows the UI updating, not the backend calculation logic.
• Believing the dashboard numerically validates the abstract's 85% precision claim; the dashboard shows descriptive UK accident statistics, which are disconnected from the Heilongjiang grey-model evaluation.
