# chart.pinchType

Equivalent to zoomType, but for multitouch gestures only. By default, the `pinchType` is the same as the `zoomType` setting. However, pinching can be enabled separately in some cases, for example in stock charts where a mouse drag pans the chart, while pinching is enabled. When tooltip.followTouchMove is true, pinchType only applies to two-finger touches.
