Excluding, Hiding, Labeling, and Selecting
This section discusses the Boolean states: conditions that are either on or off. The next section looks at the
Color, Marker, Hue, and Shade states: conditions that have many choices.
Excluded gets or sets an excluded index, which is 1 or 0 (true or false) indicating whether each row is
excluded. Similarly, Hidden gets or sets a hidden index, which is 1 for hidden or 0 for not hidden; Labeled
gets or sets a labeled index, which is 1 for labeled or 0 for not labeled; and Selected gets or sets a selected
index, which is 1 for selected or 0 for not selected. For example:
Excluded(Row State()); // returns 1 if current row is excluded, 0 if not
Hidden();
// returns 1 if current row is hidden, 0 if not
Labeled(Row State()); // returns 1 if current row is labeled, 0 if not
Selected();
// returns 1 if current row is selected, 0 if not
Excluded(Row State())=1; // excludes current row
Hidden()=0;
// unhides current row
Labeled(Row State())=1; // labels current row
Selected()=0;
// deselects current row
Recall that these functions assume the argument Row State() if none is given.
Excluded State, Hidden State, Labeled State, and Selected State do the reverse. That is, they
get or set a row state condition as true or false according to the argument. Nonzero values set the row state
to true, and zero values set it to false. Missing values result in no change of state.
rowstate()=excluded state(1); // changes current row state to excluded
rowstate()=hidden state(0); // changes current row state to not hidden
rowstate()=labeled state(1); // changes current row state to labeled
rowstate()=selected state(0); // changes current row state to not selected
