Takes in a list of time series and then counts the number of list values (=,<,>,>=,<=) RHS value in each time step.



Input Data*

Defines the time series data fed into the function. This can be a sensor ID or another function.

Convert Unit To

Allows you to convert the units by selecting from the drop-down list.

Operator=, >, <, <=, >=
ValueSensor value (i.e. value, pressure, flow rate, etc.).
TimeSeries1Defines the time series data for the first time series that will be used in the function.
TimeSeries2Defines the time series data for the second time series that will be used in the function.

*Input data is optional in most cases. If Info360 detects that the first input is time series data, it will be applied to the function. Otherwise, the current active sensor's data will be used, which is often the case in Reference Charts.

Example Usage as an Expression:

CountIfList('<', 500, {@Input A}, {@Input B}, {@Input C}, {@Input D}) - Takes Input A, Input B, Input C, and Input D time series and counts the number of time series if their values are less than 500.


  • The @ symbol is used to access the defined name of an input. When accessing a specific sensor ID, there is no need to use the @ symbol.
  • You can specify whether to use OpenHighLowClose, or Average in your expression. When this is not defined, the calculation uses the values from the data chart.

Example Reference Chart:

In the following example, a CountIfList expression in Biz Block is used to count the number of time series from Input A (Well 05 Station Flow), Input B (Well 15 Station Flow), Input C (Well 10 Station Flow), and Input D (Well 01 Station Flow) when the list values are not missing, and their values are less than 500. The resulting graph, represented by the blue line, shows the count of the time series when list values meet this condition.
