Data Visualization ▸ Hover Mode

DevExtreme Chart supports configurable hover modes for both series and points. This demo applies a common hoverMode for all series/points and a custom mode for the component legend.

You can specify hoverMode for the following Chart elements:

  • series
    A specific series.
  • commonSeriesSettings
    All series.
  • commonSeriesSettings.spline (or other Series Type objects)
    All series (specific type).
  • legend
    Series hovered in the Chart legend.
  • series.point
    Points in a specific series.
  • commonSeriesSettings.point (or other Series Type objects)
    All points.
  • commonSeriesSettings.spline.point
    All points in series (specific type).
  • argumentAxis
    All points at common argument values.

To further customize Chart behavior, define the stickyHovering property. When enabled (default), points remain in a hovered state until users hover the mouse pointer over other points or move it outside the bounds of the component.
