GS⁺ Scattergrams (Coordinate Postings)

The Coordinate Posting window provides a map of coordinate locations coded by data values. The location of each data point in the active data set is marked by a symbol corresponding to its relative value. Both the number of levels displayed as well as the range for each level is user-defined.  A similar window provides coordinate postings for 1d data.

Data may be grouped in one of three distributions:

• Quantiles – in which Z data are placed into groups of equal frequency, i.e. into groups that have the same number of sample values. Quartiles (the default graph) are divided into 4 groups, percentiles into 100 groups, etc.
  
• Intervals – in which Z data are placed into groups based on even intervals of the data range, without regard to how many sample values are placed in each group.
  
• Custom – in which you can define how individual groups are defined (upper and lower bounds).

This posting describes all data in the current Data Worksheet.
