2 Message
Splines help us to visualize the interrelationship
5 Message
of points by fitting a Smooth Curve through them.
5 Message
Splines are used primarily with Small Groups of Points.
5 Message
As we will see in a few moments, the IMPORT Module is
5 Message
much more appropriate for Larger Sets of Data.

Usually this Font is best when you have Lots of Points.
5 Message
That way they don't run all over each other on the plot.

0 Plot
0 Message
I'd use this normal Font when I have Fewer Points.
5 Message
It makes them Stand-Out better from the background.

As you can see, this Wheel is made up of some CIRCLES
6 Message
and LINES as listed in the VALUES Window on the right.
5 Message
The goal is to Identify not only the Functions Present,
5 Message
but to Solve for their various Parameters.

or Generate a new one using the KEYBOARD.
5 Message
It's best to use the keyboard for Short Puzzles only,
5 Message
leaving Longer ones for XYSee's File Editor.

Since our first puzzle will consist of a Single Function,
5 Message
we'll use the keyboard.    Ready to START?...

The next step in our preparation is to select a TOLERANCE.
5 Message
Tolerance Values define how close our guess has to be
5 Message
to Successfully Solve each piece of the puzzle.
9 Message {clear the comment line}

0 #2.0    Select a 0.2 Tolerance.
0 Message
Next we have to Select the puzzle's functions (pieces).
6 Message
We'll pick something simple,  Hmmm... a CIRCLE will do.
5 #3.0    Select a Circle for the puzzle
0 Message
Finally, we enter the parameters for its CENTER...
5 #4      X Offset of the center
1 #4      Y Offset of the center
0 Message
followed by the RADIUS!
4 #12     Radius=12 units
0 Message
Since we're only beginners, a Single-Piece Puzzle
6 Message
should do nicely.  Now let's EXIT and BEGIN!
5 Enter   Exit and activate the puzzle
