# chart.panning.type

Decides in what dimensions the user can pan the chart. Can be one of `x`, `y`, or `xy`.

During panning, all axes will behave as if `startOnTick` and `endOnTick` were set to `false`. After the panning action is finished, the axes will adjust to their actual settings.

Note: For non-cartesian series, the only supported panning type is `xy`, as zooming in a single direction is not applicable due to the radial nature of the coordinate system.
