It is possible to constrain the generated output such that it only contains the lines of data which include a particular item’s minimum and/or maximum values.
To do so, one needs only to mark in the appropriate column those items for which minimum and/or maximum values are desired. Once the request has been executed, the generated output will include for each line of data, a marker beside the value that was determined to be a minimum or maximum.
Minimum values are denoted by a “v”, and maximum values are denoted by a ”^”. Each line of data will have one of these markers.
The value of the environment variable: TABULAR_MNX_FLTR_ACCURACY dictates the number of data comparisons the software will make when determining minima or maxima. The default value is 4. Thus when determining a minimum, 4 comparisons are made with data PRECEDING the current data, and 4 comparisons are made with data FOLLOWING the current data. If the four preceding comparisons each result with a negative slope and the four following comparisons each result with a positive slope then the current data line becomes part of the output.
