Functions of columns

Let's create a second column of data, and cheat by making all its values

double the values in the first column. We can use the HOME view to avoid

having to retype the values as follows…

* Change to the HOME view and type the

command shown right, then press

ENTER.

* Press the NUM key to change back to the NUM view. You should find

your new column created and ready.

If you now use the key, you will find that you still only see statistics for

the first column (H1). The reason for this is that you have not set up the

second column in the SYMB view. The default setup is to only recognize

column 1.

Registering columns as ‘in use’

Change into the SYMB view and edit yours so

that it looks like the one on the right. You must

make sure that H2 is ed, because only

checked columns will show in the view.

Note that a screen key is provided to give you the letter C without having to

use the ALPHA key.

The stats are now available for both columns of data.

As an alternative to the method used above, you

could also have created a ‘virtual’ column of data

by using the SYMB view. Simply enter an

expression giving the new column as a function

of the old one. Although the ‘virtual’ column will

not be displayed in the NUM view, it can now be graphed and analyzed

normally.
