Spread is how many numbers around the target number you want to chart.

For example:

If the spread is 5, then 2 numbers on either side of the target number
on the wheel will be charted including the target number.

If the spread is even, the program will increase it to make the spread
odd. You can then decide what number on either side to drop off.
