@andersfriisigis,

In Range Area Chart with tooltip.shared = false, tooltip is shown only when the mouse hovers over a specific datapoint, displaying the start and end values for that range. In multi-series chart, it will not combine values from different series and will show information for the hovered datapoint only. When tooltip.shared = true, the tooltip appears even when not hovering directly over a datapoint, displaying information for the nearest datapoint based on the x-value and y-values across all the series.
