markerVisibility property
Whether marker should be visible or not when trackball is enabled.
The below values are applicable for this:
- TrackballVisibilityMode.auto - If the isVisible property in the series
markerSettings
is set to true, then the trackball marker will also be displayed for that particular series, else it will not be displayed. - TrackballVisibilityMode.visible - Makes the trackball marker visible for all the series,
irrespective of considering the isVisible property's value in the
markerSettings
. - TrackballVisibilityMode.hidden - Hides the trackball marker for all the series.
Defaults to TrackballVisibilityMode.auto
.
Also refer TrackballVisibilityMode.
