W Field
The W Field contains a wave represented by a list of points with two coordinates and stored as real numbers.
As the W-Field also has a name, the input string should have the following format:
“Name ¶ X1 ¶ Y1 ¶ X2 ¶ Y2 ¶” etc., where “¶” represents the subfield separator given in the import options.
Ex: “¶1¶23¶2¶34¶3¶45¶4¶46¶”.
Merging data is not supported and the imported data always replaces the existing information.
