Cow Event Analysis graphs allow you to focus on individual events for specific lactations or days in milk, and are an invaluable resource for tracking and investigating your herd's unique health profile in greater detail. The graphs are located on the [Cows](docId:3flGfwCd6NDQLAiXFgUzX) page, below the main trends graph.

Follow the guidelines below when working with Event Analysis graphs.

1. Benchmark assigned: Based on your [customization settings](docId\:NwuxaSN9egAdX1s1tThH6), your cows are compared to herds of similar locale and size. The blue bar identifies the benchmark details.
2. Event line: Use the solid colored line

to view total cases and percentage (%) of affected cows by month. The light blue bar indicates the total number of cows, and hovering over the graph provides details by month.\:::hint\{type="info"}
**NOTE: **For quick association, the HealthVAL line color matches the color currently defined for the event. See [Edit Event Definitions](docId\:m_xV2dsSKybZQUA395F8Z) for more information.

3. Herd Event Trend: Use the gray dotted line

4. Event Bench: If benchmark data exists, you can compare your herd trend curve to the benchmark curve

5. Click **Occurrence** to view the reference data in occurrence percentages and include threshold values on the graph, or click **Count** to view the reference data in total counts.
6. Threshold: The red dashed line

7. Hover over a bar on the graph to view additional data.
8. If the graph includes data for the current month, the bar is shaded to indicate that data for the month is incomplete.
