Adding Numeric Equal Distance Bucketing

Numeric data is represented as a continuous set of values in displays and filters.  Sometimes it may be necessary to divide the data into equal sized bucket subsets.

For example, for the 1 Day Change %(USD) column, the minimum value is -0.35 and the maximum value is 0.21 when you specify 2 buckets, the equal distance ranges will be the following:

q  -0.35, -0.07

q  -0.07, 0.21

Meanwhile, if you specify 3 buckets, the equal distance ranges will be the following:

q  -0.35, -0.17

q  -0.17, 0.02

q  0.02, 0.21

These can be achieved with Equal Distance bucketing and is commonly used when producing histograms.

The Calculated Columns pane displays.

2.     Click New Column > Numeric Bucket.


The numeric bucket instance is displayed on the Data Sources Settings with Numeric Bucket as the default title, also the Numeric Bucket Column pane displays.
