Defining Buckets for Split

In the KS6800A environment, a bucket can be defined as a slot that contains one or more measurement or property values, based on the type of field you select for splitting charts.

As mentioned earlier, the Splits pane is where you can define buckets to split all plotted charts or only a selected chart.

The areas shown in the Split pane are:

  1. Overview—displays information about the split, where the field name and number of buckets (auto-defined for the split) is displayed. The buttons - Fewer buckets and + More buckets are available if the numeric or date & time values must be distributed across a minimum of two buckets or a maximum of five buckets. These buttons are inactive for all alphanumeric / text values (that is, fields with string or bool data types).
  2. Method—displays the method of auto-distribution of values for split. By default, Equal Counts is highlighted, which indicates that each bucket will have equal number of values from the field. You can switch to the other option, Equal Ranges, which indicates that each bucket will have equal size for value range from the field. Selecting any of these options is not allowed for all alphanumeric / text values (that is, fields with string or bool data types).
  1. Buckets—displays the distributed value range for each bucket, depending on the Method you select. The KS6800A software automatically distributes the numeric data (with int32 or float64 data types) and date & time data (with timestamp(ms) data type) from the selected field into three buckets, by default. For such values, you have the option to reduce the number of buckets (using the buttons in the Overview area) to a minimum of two and a maximum of five. For alphanumeric or text data (with string or bool data types), the KS6800A uses all values (up to five) to define buckets. However, you cannot modify such buckets in any manner.
  2. Actions—displays buttons to apply the defined buckets for split either on all plotted charts or a specific chart. After you define buckets, the Apply Split Globally as Filters button is enabled by default. However, the Apply Split Within Selected Chart button is enabled when you select a specific chart (of Box and Whisker, Scatter or Summary Line type) only. To see how these actions impact the plotted charts, see Applying Split Globally as Filters and Applying Split Within Selected Chart, respectively.
