Gets or sets the method used to specify the histogram intervals.

[Visual Basic]

Public Property IntervalCreationMethod As IntervalMethodEnum

[C#]

public IntervalMethodEnum IntervalCreationMethod {get;set;}

[Delphi]

public property IntervalCreationMethod: IntervalMethodEnum read get_IntervalCreationMethod write set_IntervalCreationMethod;

Remarks

Interval boundaries can be established in a variety of ways.

When the Automatic method is used, the chart calculates the upper and lower limits of the intervals using the maximum and minimum data values, and restricting the intervals to lie within 3 standard deviations of the data mean. The number of intervals is optional. Interval boundaries are calculated uniformly.

When the SemiAutomatic method is used, the upper and lower limits of the intervals are specified together with the number of intervals. Interval boundaries are calculated uniformly.

When the XDataBoundaries method is used, the X values of the data data series are used to explicitly set each interval boundary. The X values are sorted and duplicate values are eliminated. Each ascending value of the result is used determine the next interval boundary. Thus, the first and second resulting X values define the first interval and each successive X value specifies the end of the next interval. Note that specification of N intervals requires N+1 unique X values.
