# series.dependencywheel.tooltip.followTouchMove

Whether the tooltip should update as the finger moves on a touch device. If this is `true` and chart.panning is set,`followTouchMove` will take over one-finger touches, so the user needs to use two fingers for zooming and panning.

Note the difference to followPointer that only defines the position of the tooltip. If `followPointer` is false in for example a column series, the tooltip will show above or below the column, but as `followTouchMove` is true, the tooltip will jump from column to column as the user swipes across the plot area.
