Maybe you can adapt the attached demo.

I'd probably use scatter() where you can specify the color of each data point.
numSpots = 50; % Whatever you want.
markerSize = 100; % Whatever you want.
radius = 10; % Whatever you want.
angles = linspace(20, 270, numSpots); % Whatever starting and stopping angles you want.
x = radius * cosd(angles);
y = radius * sind(angles);
% Make up some colors for the data points,
% like one that follows the jet colormap for example.
spotColors = jet(length(x));
% Plot dots in a scatter plot.
scatter(x, y, markerSize, spotColors, 'filled');
grid on;
xlabel('x', 'FontSize', 15);
ylabel('y', 'FontSize', 15);
