hello i"m trying to graph a bar plot from form .1 to .9 based on this index p=.1:.1:.1 but its graphing from it seems to be plotting from about -.3 to 1.3 can someone help me please fix this
win=0 step=0 for p=.1:.1:.9
for i=1:1:100
a=3
b=3
c=3
while a>0 && b>0 && c>0
step=step+1
d=rand(1,3)
if d(1,1)<p && d(1,2)<p && d(1,3) <p
a=a+0
b=b+0
c=c+0
elseif d(1,1)>p && d(1,2) >p &&d(1,3) >p
a=a+0
b=b+0
c=c+0
elseif d(1,1)<p && d(1,3) < p
a= a -1
b= b+2
c= c-1
elseif d(1,1)>p &&d(1,3) >p
a= a -1
b= b+2
c= c-1
elseif d(1,3)<p &&d(1,2) < p
a= a +2
b= b-1
c= c-1
elseif d(1,2)>p && d(1,3) >p
a= a +2
b= b-1
c= c-1
elseif d(1,1)<p &&d(1,2) < p
a= a -1
b= b-1
c= c+2
elseif d(1,1)>p && d(1,2) >p
a= a -1
b= b-1
c= c+2
end
end
win=win+1
end
%axis([0 1 0 75])
avg=step/100
bar(p,avg)
hold on
end

A quick fix is to put the following line after your bar() command:
>> set(get(gca,'Children'),'BarWidth',0.1)
The problem is that your bars are being plotted with width 0.8, by default. Then, each one overlaps the previous ones. If you put a breakpoint just after that bar() command, and see each bar being put down, you'll see what I mean.
A better solution, but which I am too lazy to implement for you, would be for you to get all the values of p and avg stored into vectors, then do the bar plot with the vectors, outside the loop. Then MATLAB would do the work of adjusting the widths appropriately.
