Mask channel
|
Select a mask channel from the dropdown list. If the use of the mask channel is enabled, and set to this channel, only those data values whose corresponding mask channel value is not a dummy will be plotted or exported.
Channels must have their CLASS attribute set to MASK to appear as selections in the drop-down list. If the mask channel does not exist, it will be created with its CLASS attribute set to MASK.
The default mask channel is set from the CHPREFERENCES GX (Geochem Import/Preferences...).

Grouping
|
Grouping in the plot. If "Group by line/group" is selected, then symbol attributes can only be edited for entire lines or groups. If "Individual symbols" is selected, the symbols can be edited individually. The former selection is the default, and will be faster, especially for very large data sets.
Script Parameter: CHSYMB.GROUP (0: Individual, 1: Group (default)

Offset symbols?
|
If "Yes" is selected, symbols are offset from their actual locations and replotted so that overlap is avoided. The original location and the new location are joined with a line, and a small filled circle is plotted at the original location. Care should be taken when choosing the symbol size, because if the point density is too high, all the points will get pushed to the outside edge and your plot will look like a hedgehog (it also takes a lot longer!).
The algorithm should work perfectly for the pie symbols, because they are all the same size. For the rose plots and bar plots an estimate of the average size is made and used to determine spacing and locations, so some overlap may occur for high-value data locations.
