Methods

This section describes the methods that can be used in code to manipulate the Series object.

clearSelection()

Unselects all the selected points of the series. The points are displayed in an initial style.

To learn about point selection, refer to the Selection Handling section.

Show Example:
jQuery

In this example, click a series to select it. Then, click it once again to deselect it. The deselection is performed using the clearSelection() method.


                                    

                                    

deselectPoint(point)

Deselects the specified point. The point is displayed in an initial style.

Parameters:
point: Object

The point to be deselected.

To learn about point selection, refer to the Selection Handling section.

Show Example:
jQuery

In this example, if you click a series, only points with the value equal to 20 or more will be selected. The second click on the series deselects all previously selected points using the deselectPoint(point) method.


                                    

                                    

getAllPoints()

Returns an array of all points in the series.

Return Value: Array

The points from the series point collection.

Show Example:
jQuery

In this example, the maximum point value in the clicked series is displayed. The series' getAllPoints() method is used to calculate the maximum value from all the points.


                                    

                                    

getPointByArg(pointArg)

Gets a point from the series point collection based on the specified argument.

Parameters:
pointArg: Number|String|Date

The argument of the point to be found.

Return Value: Object

The point that is found by the specified argument.

If a point with the specified argument is not found, the function returns null.

Show Example:
jQuery

In this example, choose one of the countries using the radio buttons. Here, the getPointByArg(pointArg) method is used to select points according to the argument, which is the chosen country.


                                    

                                    

getPointByPos(positionIndex)

Gets a point from the series point collection based on the specified point position.

Parameters:
positionIndex: Number

The index of the point to be found within the series point collection.

Return Value: Object

The point that is found by the specified position index.

Points in the series point collection are arranged as they go along the argument axis from left to right. Note that the series are numbered from zero in the series collection.

Show Example:
jQuery

In this example, choose one of the point indexes using the radio buttons. Here, the getPointByPos(positionIndex) method is used to select all points with the chosen index.

To learn about series selection, refer to the Selection Handling section.

Show Example:
jQuery

In the example below, click a series to select it. Then, click it once again to deselect it. The selection is performed using the select() method.
