title: Scalars Reporting
---

The [scalar_reporting.py](https://github.com/clearml/clearml/blob/master/examples/reporting/scalar_reporting.py) script
demonstrates explicit scalar reporting. ClearML reports scalars in the **ClearML Web UI** **>** task's **SCALARS** tab. 

When the script runs, it creates a task named `scalar reporting` in the `examples` project.

## Reporting Scalar Series 
To report scalar series, call [`Logger.report_scalar()`](../../references/sdk/logger.md#report_scalar). 
To report more than one series on the same plot, use the same `title` argument. For different plots, use different 
`title` arguments. 

```python
# report two scalar series on the same graph
for i in range(100):
    Logger.current_logger().report_scalar(
        title="unified graph", series="series A", iteration=i, value=1./(i+1)
    )
    Logger.current_logger().report_scalar(
        title="unified graph", series="series B", iteration=i, value=10./(i+1)
    )
    
# report two scalar series on two different graphs
for i in range(100):
    Logger.current_logger().report_scalar(
        title="graph A", series="series A", iteration=i, value=1./(i+1)
    )
    Logger.current_logger().report_scalar(
        title="graph B", series="series B", iteration=i, value=10./(i+1)
    )
```

## Reporting Single Scalar Values 

To report single scalar values (individual metrics, not part of a series), use [`Logger.report_single_value()`](../../references/sdk/logger.md#report_single_value).

```python
# Report individual scalar values
Logger.current_logger().report_single_value(name="metric A", value=486)
Logger.current_logger().report_single_value(name="metric B", value=305.95)
```

Single value scalars are shown in the UI in the task's **SCALARS** tab under the `Summary` table.
