在MATLAB中绘制无线的2D点

Question

I have some 2D points and I want to plot them in MATLAB such that every point has a different color and specifier. I have used plot function but it creates line whatever you give. I want to draw these points as discrete points only. How can I do that? Here is what I am trying to achieve in the simplest form (I used TikZ below):

UPDATE: Thank you for your comments and answers, I have the following code right now:

x = [  0.56, 0.4526, -0.4324, 0.2749, -0.2993, 0.3404, 0.1959, 0.3363, -0.1706];
y = [0.1999, 0.3939,  0.1999, 0.4414,  0.2000, 0.3931, 0.1999, 0.3966,  0.4056];

figure
plot(x(1),y(1),'rx')
hold on
plot(x(2),y(2),'*','Color','[0 0.9 0]')
hold on
plot(x(3),y(3),'*','Color','[0 0.5 0]')
hold on
plot(x(4),y(4),'o','Color','[0.47 0.52 0.8]','MarkerFaceColor','[0.47 0.52 0.8]')
hold on
plot(x(5),y(5),'o','Color','[0.05 0.28 0.63]','MarkerFaceColor','[0.05 0.28 0.63]')
hold on
plot(x(6),y(6),'s','Color','[1 0.71 0.30]','MarkerFaceColor','[1 0.71 0.30]')
hold on
plot(x(7),y(7),'s','Color','[0.9 0.32 0]','MarkerFaceColor','[0.9 0.32 0]')
%plot(x(7),y(7),'s','Color','[1 0 0.5]','MarkerFaceColor','[1 0 0.5]')
hold on
plot(x(8),y(8),'d','Color','[0.67 0.28 0.73]','MarkerFaceColor','[0.73 0.40 0.78]')
%plot(x(8),y(8),'d','Color','[0.67 0.28 0.73]','MarkerFaceColor','[0.67 0.28 0.73]')
hold on
plot(x(9),y(9),'d','Color','[0.29 0.08 0.55]','MarkerFaceColor','[0.29 0.08 0.55]')
xlabel('X')
ylabel('Y')
h = legend('(^1X,^1Y)','(^2X_1,^2Y_1)','(^2X_2,^2Y_2)','(^3X_1,^3Y_1)','(^3X_2,^3Y_2)','(^4X_1,^4Y_1)','(^4X_2,^4Y_2)','(^5X_1,^5Y_1)','(^5X_2,^5Y_2)');
set(h,'Location','best')
grid

I can now draw the points as dots with different colors and specifiers although this way may not be the best way.

You can simply specify the LineSpec option

To obtain your example:

plot(xdata, ydata, '.')
