The dedicated Charts button activates a core analytical feature that visualizes the performance history of the Frequency Rate (FR) and Severity Rate (SR). This functionality provides crucial insights through two distinct temporal views: short-term monthly trends and long-term historical performance.

1. Current Year Monthly Trend Analysis

This view provides stakeholders with a granular, short-term perspective on safety performance.

• Data Scope: Displays the calculated FR and SR indices on a month-by-month basis for the current reference year.

• Purpose: Allows for timely identification of seasonal variations, direct monitoring of the impact of recent safety initiatives, and immediate comparison against monthly goals.

• Visualization: The trend line clearly shows whether the indices are improving or deteriorating throughout the year, facilitating quick corrective action.

2. Overall Historical Annual Trend

This view offers a high-level, long-term perspective on the company's safety journey.

• Data Scope: Displays the overall annual aggregated FR and SR indices across all available historical years.

• Purpose: Enables executive review of safety strategy effectiveness over time, benchmarking long-term improvement or regression, and validation of large-scale, multi-year programs.

• Visualization: Users can assess macro-level trends and understand the company’s trajectory relative to past performance, providing essential context for future planning.

The combination of these two chart types ensures that users have both the immediate detail needed for tactical adjustments and the broad context required for strategic safety management.
