Representation of a histogram.

The Histogram can be seen as an integer array of value counts divided into bins from a specified minimum to maximum value. Bins are accessed via their absolute position, regardless of specified minimum bin.

int

Methods

Add(int)

Increment histogram at bin position value.

public void Add(int value)

Parameters

value int

Bin position at which histogram should be incremented.

ApplyWindow(int)

Define WindowStart and WindowEnd properties by gradually shrinking the window until the value count inside the window is less than or equal to percent % of the total value count.

public void ApplyWindow(int percent)

Parameters

percent int

Target percentage for the active window.

ApplyWindow(int, int)

Apply an active histogram window at the specified start and end bins.

public void ApplyWindow(int start, int end)

Parameters

start int

Position of the window's start bin.

end int

Position of the window's end bin.

Clear(int)

Reset histogram at bin position value to 0.

public void Clear(int value)

Parameters

value int

Bin position at which histogram should be reset.
