HoverMode

public enum HoverMode : Encodable

Determines the mode of hover interactions.

If closest, a single hoverlabel will appear for the closest point within the hoverdistance. If x (or y), multiple hoverlabels will appear for multiple points at the closest x- (or y-) coordinate within the hoverdistance, with the caveat that no more than one hoverlabel will appear per trace. If x unified (or y unified), a single hoverlabel will appear multiple points at the closest x- (or y-) coordinate within the hoverdistance with the caveat that no more than one hoverlabel will appear per trace. In this mode, spikelines are enabled by default perpendicular to the specified axis. If false, hover interactions are disabled. If clickmode includes the select flag, hovermode defaults to closest. If clickmode lacks the select flag, it defaults to x or y (depending on the trace’s orientation value) for plots based on cartesian coordinates. For anything else the default value is closest.
