Comments:
1: Initial (0,1) coordinate at top of circle. Extra 0 included for sort.
2: Coordinates to create mark at 12 o\'clock.
3: Coordinates to draw initial circle. Joins markers every 10 degrees starting from 0 at top of circle, e.g. 0, 10, 20, 30,...360
4: Sequence of coordinates every 30 degrees to create small markers for hours 1, 2, 4, 5, 7, 8, 10, 11
5: Sequence of coordinates to connect the 30 degree small markers. Needed to place them correctly on circle.
6: Sequence of coordinates every 90 degrees to create large markers for hours 12, 3, 6, 9
7: Sequence of coordinates to connect the 90 degree large markers. Needed to place them correctly on circle.
8: QUERY function used to sort the circle data by the degrees column, then select just the (x,y) coordinate columns (numbers 2 and 3) to use.
9: Coordinates to create the minute hand. Includes an IF statement to avoid an error when the minute hand arrives at the 12 mark.
10: Coordinates to return to centre of clock at (0,0) after minute hand, to be ready to draw hour hand.
11: Coordinates to create the hour hand.
12: Set linewidth of the Sparkline to 2.
