# Enum ThresholdMode

Represents the behavior when determining which data points to get merged.

**Namespace**: Telerik.Reporting

**Assembly**: Telerik.Reporting.dll

#### Syntax

`public enum ThresholdMode`

**Remarks**

Each mode requires accompanying threshold number in specific range.
To compare and order the data points each data point gets associated with a value.
This value gets evaluated from appropriate definition expression.
For example, the BarSeries data points value expression
is the

#### Count

The threshold value should be an integer number determining how many data points should be presented on their own (without being merged) at most. The data points are first ordered by their value. All data points appearing after the count of points determined by the threshold value get merged. For example, in a set of 10 data points and threshold value of 3, all but the top 3 data points will get merged.

#### PercentageCount

The threshold value should be a decimal or integer number between 0 and 100 and represents a percentage of the count of the data points that should be presented on their own (without being merged). The data points are first ordered by their value. Then the count of the data points that are not merged is calculated as a percentage of all data points count. For example, in a set of 10 data points and threshold value of 40, all but the top 4 data points will get merged.

#### PercentageValue

The threshold value should be a decimal or integer number between 0 and 100 and represents a percentage of the summary value of all data points. Once the absolute threshold value gets calculated all data points having value less than it get merged. For example, in a set of 10 data points with values from 1 to 10, the summary value is 55. If the threshold value is 10, it means the absolute threshold value is 55 * 10% = 5.5 . This means that all data points with value smaller than 5.5 will get merged.

#### Value

The threshold value should be a decimal or integer number representing the minimum value that a data point should have in order to get presented on its own (not getting merged). All data points having value less than the threshold value get merged. For example, in a set of 10 data points with values from 1 to 10, if the threshold value is 8.5, all data points having value less than 8.5 will get merged.
