Histogram

Chart type that represents frequency distributions of certain events or values.

Only one signal is allowed as input for the x axis. The y axis can be modified by using display types.

Display Types
  • value (default):

    Representation of the frequency distribution of a value in absolute number

  • percent:

    Representation of the frequency distribution of a value in percent

  • durationAbs:

    Overview of the duration of a value in absolute number; you must specify at least one condition or two triggers (start+end), otherwise you get the view of value / percent.

  • durationPercent:

    Overview of the duration of a defined event shown relative to the data samples selected by the intervals. You must specify at least one condition or two triggers (start+end), otherwise you get the view of value / percent.

    Example:

  • steps:

    Number of times each value was observed. Continuous segments where the value is consistently present are only counted once.

    Example 1:

    Example 2:

  • bar (for bit signals only):

    Frequency of states to evaluate multiple bit signals; no quantity and range need to be set.

In the generated report, you can switch the display type again.

Note  

A subtype of the histogram is "histpie" that represents the data as proportions of a circle. This subtype can only be configured within the EATB APIs.
