A: ioGAS displays the sample number and the values for the displayed axes for many of the plots in ioGAS.  The cursor must be over the data point of interest for these values to display.  Only one value is displayed at a time.  For example, on the map view, the sample ID, northing, easting, and variable value are all displayed in a pop-up text box when the cursor is hovered over a plotted point.  If this information is not displaying, check that there are columns set as ‘Sample ID’, ‘North’, ‘East’ in the Column Properties dialog.  If you wish to view other columns as metadata, go to the Data>Select Labels menu option and add some more text columns to display.
