You can use the RemoveDuplicateDataText property to control whether data text values that are the same for two or more series are represented by a single data text value or are repeated.

Syntax:

setRemoveDuplicateDataText(boolean);

boolean = getRemoveDuplicateDataText();

where:

boolean

Can be one of the following:

true removes duplicate text values.

false does not remove duplicate text values. This value is the default.

Example:

With setRemoveDuplicateDataText(false), the points where the two series have the same data value show that value twice:

setRemoveDuplicateDataText(false);

With setRemoveDuplicateDataText(true), the points where the two series have the same data value show that value once:

setRemoveDuplicateDataText(true);
