Constructors
| Icon | Type | Description |

Properties
| Icon | Type | Description |
|---|---|---|
 | Bins |
Returns the HistogramBinCollection
for this histogram.
|
| DataLength |
Gets the total number of data cells in the DataArrayBase.
|
| Length |
Gets the total number of cells in the design.
|
| Rank |
Gets the rank (number of dimensions) of the DataArrayBase.
|
| TotalValue |
Gets the sum of all bin values.
|
Remarks
Use the Histogram class to represent frequency data.
Every histogram object has an associated NumericalScale
that defines the categories into which the data is to be sorted.
The Bins collection contains the individual bins. To tabulate individual values, use the Increment(Double, Double) method. To tabulate all of a variable's observations, use the Tabulate(Double[]()) method.
The bin totals can be retrieved using the GetTotals() method, and set and cleared using the SetTotals(Double[]()) and Clear() methods.
To test how well a histogram fits a distribution, use one of the GetGoodnessOfFitTest(Distribution, Int32) methods.
