Port’s Number Chart widget already supports display formatting options, including rounding to the nearest integer and setting custom decimal precision. However, this capability is not available in the Line Chart widget. As a result, values shown in line charts (such as averages or aggregated metrics) can appear with long and hard-to-read decimal values.

We would like the Line Chart widget configuration to include a display formatting option, similar to the Number Chart widget. At a minimum, this should support rounding to the nearest integer, with an optional custom precision setting (e.g., 0, 0.0, 0.00). This would improve readability for use cases such as DORA metrics, aggregated incident trends, and dashboards designed for non-technical stakeholders.
