Examples

EX1

This example shows how to set column as categorical. This script imports data, filters the data, sets a column of data as categorical then sorts the filtered categories in ascending order using wks.col.categorical.sort. Ordering becomes important when creating the stack plot. Sorting in ascending order then plotting the stack "top to bottom" preserves alphabetical ordering of categories, from top to bottom.

// import automobile.dat to a new book
fn$ = system.path.program$ + "Samples\Statistics\automobile.dat";
newbook;
impASC fn$;
// apply filter to column = Make to show only Buick Chrysler GMC Lincoln Saturn
wks.col2.filter=1;
wks.col2.filterx$ = make;
wks.col2.filter$ = "make="Buick" or make="Chrysler" or make="GMC" or make="Lincoln" or make="Saturn"";
wks.runfilter();
// set col(2) as categorical and sort in ascending order
wks.col2.categorical.type=2;
wks.col2.categorical.sort=1;
//refresh column filter
wks.runfilter();
// unstack worksheet to columns by make
wunstackcol -r 2 irng1:=[%H]automobile!C"Power" irng2:=[%H]automobile!B"Make" nonstack:=1 other:=[%H]automobile!A"Year" extract:=0;
// create stack plot of col(1) vs. col(2) to end, type=scatter
