Use the Scatter Tool to Define Masking Limits

Defining mask limits and posting the mask values onto a map is one of the many features of the Geochemistry tools.

A ‘mask’ channel can be used for selecting a subset of data values from the database. When a mask channel is selected, it will be used and updated by the dialog as selections are plotted. A data value is highlighted in red if its corresponding mask value is not a "dummy" value.
