在 MATLAB Online 中打开

data = rand(120,3)
figure, hold on
plot(data(:,1),'go')
plot(data(:,2),'ro')
plot(data(:,3),'bo')
set(gca,'Color','k')

If you wanted, say, filled circles with a white outline:

figure, hold on
plot(data(:,1),'wo','MarkerFaceColor','g')
plot(data(:,2),'wo','MarkerFaceColor','r')
plot(data(:,3),'wo','MarkerFaceColor','b')
set(gca,'Color','k')
