Using Lists & Spreadsheet 569
5. Replace the letters “
var
” with the name of the variable to capture.
For example, type
objpathX
. Alternatively, you can select the variable
name from the Variables menu.
The formula cell now contains an expression similar to
=capture(objpathX,1)
.
Note: The argument “
1
” tells Lists & Spreadsheet that you want the
captures to be triggered by the variable change.
6. If you want the capture to also be triggered by changes in an
additional variable or variables, type a comma after the
1
, and then
type the variable name or the name of a list that itemizes the
variables.
The formula cell wil contain an expression similar to
=capture(objpathX,1,objpathY) .
7. Press
·
to complete the formula.
8. If you are capturing multiple columns of synchronized data, set up
the additional columns. For example, you might set up a second
capture variable using
=capture(objpathY,1,objpathX) .
9. When you are ready to capture the values, begin moving the object
or start the animation that affects it in Graphs & Geometry.
Each captured value is added to the end of the list.
Using table data for statistical analysis
Tools on the Statistics menu provide access to wizards that help you
perform statistical analyses on the data in table columns. You specify the
location of the data, and Lists & Spreadsheet stores the results in two
columns: one for the result names, and one for the corresponding values.
