How to plot two independent curves as symbols in one graph?

GOAL: I have two independent arrays y1 and y2 and want to plot them depending on x1 and x2 in the same graph. The curves should be plotted as symbols and not as lines. I wrote the following lines:

X1=[1:99,1]';
X2=[1:199,1];
Y1=rand(100,1);
Y2=rand(200,1)*-1;
h=plot(X1,Y1,X2,Y2);
axis([0 200 -1 1])

%Curve Properties
set(h,{'Color'},{'r';'g'})
set(h,{'LineStyle'},{'s';'v'})
set(h,{'MarkerSize'},{4;4})

PROBLEM: Unfortunately, the curves are not plotted as symbols and the colors are not accepted also. I obtain the following error:

Error using set
Value cell array handle dimension must match handle vector length

I read the instructions to use "set" but did not understand how to correct the command lines. I wonder if someone could help me to fix this.

Thank you in advance for your attention

I don't have any problem with your code, what version of MATLAB are you using? Do these work for you?

 X1 = [1:99,1]';
 X2 = [1:199,1];
 Y1 = rand(100,1);
 Y2 = rand(200,1)*-1;
 plot(X1,Y1,'rs','markersize',4); hold on;
 plot(X2,Y2,'gv','markersize',4)
 axis([0 200 -1 1])

Another way:

 X1 =[1:99,1]';
 X2 =[1:199,1];
 Y1 = rand(100,1);
 Y2 = rand(200,1)*-1;
 h = plot(X1,Y1,X2,Y2);
 axis([0 200 -1 1])
 set(h(1),'color','r','linestyle','s','markersize',4);
 set(h(2),'color','g','linestyle','v','markersize',4);

Hi Wayne, thank you for your help, this definitely help. However, I kept trying and if instead of two graphs I plot three at once, thus: x1y1, x2y2, and x3y3, then the commands are fine. Try below:

clear all;
close all;
X1=[1:99,1]';
X2=[1:199,1];
X3=[1:49,1];
Y1=rand(100,1);
Y2=rand(200,1)*-1;
Y3=rand(50,1);
h=plot(X1,Y1,X2,Y2,X3,Y3);
axis([0 200 -1 1])

%Curve Properties
set(h,{'Color'},{'r';'g';'b'})
set(h,{'LineStyle'},{'s';'v';'d'})
set(h,{'MarkerSize'},{6;6;6})
set(h,{'MarkerEdgeColor'},{'k';'k';'k'})
set(h,{'MarkerFaceColor'},{'r';'g';'b'})

This is very puzzling, do you know what is going wrong in case of two graphs and why it works in case of three?

Thank you again for your help

I don't have any problem with your initial code with just two. What version are you using?

Interesting, I use R2012a, and now it is working also. It may have happened that I accidentally removed the comment % from the line Curve Properties. I tried this and the plot is executed but with the error above. I'm very sorry and thank you a lot for your help. Wish you a nice day
