# series.geoheatmap.accessibility.point.descriptionFormatter

Formatter function to use instead of the default for point descriptions. Same as `accessibility.point.descriptionFormatter`, but applies to a series instead of the whole chart.

Note: Prefer using accessibility.point.valueDescriptionFormat instead if possible, as default functionality such as describing annotations will be preserved.
