Class ConsoleHistogramFormatter<T>

  • Type Parameters:
    T - The type of value the histogram counted, which this formatter will format using the provided upperBoundValueFormatter parameter.
    public class ConsoleHistogramFormatter<T>
extends Object
    Format Histogram contents for a text display. The formatted output consists of a vertical list of labeled histogram buckets, with horizontal bar graphs showing the count in each bucket, followed by a percentage that represents the number of items counted in this bucket as a fraction of all items counted by this histogram.

    Example: 

         <= 1 ******                                                         4%
     <= 2 *********************                                         15%
     <= 4 ************************************************************  43%
     <= 8 ************************************************              34%
     >  8 *****                                                          4%
