Fields that provide information on the series point.
Provides information about the state of the point object.
Each point within a chart can be in several states. These states are represented by the numbers that are enumerated in the list below:
The point is not hovered and not selected (normal state);
The point is hovered;
The point is selected;
The point is hovered and selected.
You can also use the isHovered() and isSelected() point methods to check whether a point is hovered or selected.
In this example, the point's fullState field is used to implement unselecting of a selected point. The function, which is assigned to the onPointClick option, checks the current state of the clicked point. If the point is selected, the selection will be removed using the clearSelection() method. Otherwise, the point will be selected using the point's select() method.
Returns the point's argument value that was set in the data source.
Returns the point's value that was set in the data source.
Gets the percentage value of the specific point.
Returns the series object to which the point belongs.
For information on members that a series object exposes, refer to the Series object description.
Returns the tag of the point.
When defining a data source, you can provide auxiliary information for each point by adding a tag field to the data source, and specifying the name of the field via the tagField option of the series.
