You can add context metrics to provide a better understanding of the main metric displayed on the chart. Context metrics are displayed as tooltips on charts.

The following illustration shows a chart with the main metric **Average amount** and **Number of cases** as a context metric.

Depending on the calculation of the main metric, different contexts may be useful to explain the main metric. For example, if the main metric is defined as `Average amount`, useful context is `Number of objects` for which the average amount is calculated. This also applies when you main metric is defined as `Total amount`. In this case, also `Number of objects` for which the sum is calculated is a useful context.

When your main metric is defined as a percentage, for example `Cases with tag (%)`, useful contexts can be `Number of objects with tag` and `Total number of objects`.

The following table shows some examples of main metrics with relevant context metrics.

|  | Main metric | Context metric 1 | Context metric 2 |
| --- | --- | --- | --- |
| **Count** | Number of objects  `112` | - | - |
| **Average** | Average amount  `€ 61,43` | Objects  `112` | - |
| **Sum** | Total amount  `€ 123.555,00` | Objects  `112` | - |
| **Percentage** | Objects with tag %​  `60%` | Objects with tag  `600` | Total objects  `1000` |
