MATLAB: Problem in drawing

MATLAB

After greeting and respect
Every time when I want to do my program,everything is stop in graph
(plot),I know how to do the program but the main problem for me in
plot,so this is my program and Graphic shows is not clear,why???
can any one tell me
rand('state',0)
M=input('Enter the number of realization:');
count=0;
X=randn(M,1);
proestimated = zeros(size(X));
for k=1:M
if X(k)>2 count=count+1;
end
end
proestimated = count/M;
disp('estimated probability:')
display(proestimated)
y=@(X)(1/sqrt(2*pi))*exp(-0.5*X.^2); % Anonymous func.
True_probability = quadgk(y,2,inf)
bar(X,True_probability);
hold on
grid on
xlabel('X');
ylabel('True probability');
title('True probability pdf');
bar(X,proestimated);
hold on
grid on
xlabel('X');
ylabel('Estimated probability');
title('Estimated probability pdf');
anybody help me in plot the graph in my program
Thanks in advance

I get a graph, why do you say you don't get a graph? You don't say what to use for the requested input, so I used 10000. Is that wrong? If so, what should we use?
