MATLAB Helper Function - Price is Right Wheel Sketch

Draw 5 spaces of the wheel to the screen, the arrow, and populate the initial pricing array with all as global variables.

function drawWheel ()

global priceWheel;
global priceText;
global priceArrow;
global priceSpace;
global pricePos;

pricePos = int16(0);

% Price order (from Wiki)

    priceWheel = {'0.05','1.00','0.15', '0.80', '0.35', '0.60', '0.20', '0.40', '0.75', '0.55', '0.95', '0.50', '0.85', '0.30', '0.65', '0.10', '0.45', '0.70', '0.25', '0.90'};    

    for j=1:5                
        priceText(j) = writeText(25.5, 37.5-j*5.25, priceWheel(j));
        
        set(priceText(j),'FontName','FixedWidth')
