Application Notes

Selection of Lines

This GX will yield a summary of all the selected lines. You can use the line selection tools command in the Data menu to select lines to be included if you run the GX interactively, or the SELECT command if you are using a GS script for batch processes.

Channels

You can obtain a summary statistics report for a single channel or for multiple channels. Single channels may be chosen from a drop down list. Multiple channels may be manually entered but must be comma separated. If you leave the entry blank, all displayed channels in your database will be summarized. As for array channels the statistics for the entire array is reported, followed by the statistics for each individual array element. Calculation of statistics will be carried out only if the data type of a channel is not set to STRING. For STRING type channels, only the channel names will be output to the summary file. Also note that the calculation of statistics is based on the raw data of each channel. If two channels of a given line in a database have different fiducial start and increment, the number of elements used in the calculation in each channel may differ. These channels are recognized by the red underlining of the channel name in the database.

Statistics

The statistics for the X and Y channels are always included in the statistic summary if they are present in the database. The statistics calculated for the X and Y channels include the minimum and maximum values, total distance and the number of points and dummy values.

The statistics calculated for each additional channel include the minimum value, the maximum value, the arithmetic mean, the standard deviation and the number of valid points. These are calculated for each line separately and also for the entire selected data set.

Suppressing Display of the Stats File in Script Mode

To prevent the automatic display of the log file when running this GX from a script, set the following script parameter:

XYZSTAT.SHOWLOG = 0

This setting must be made before each run of the XYZSTAT GX, as the parameter is reset to 1 by XYZSTAT each time in order to ensure the default behaviour.
