my code::
function SumDice=RollDice(NumDice,NumRolls)
NumDice=1
NumRolls=500
distribution=zeros(NumDice*6,1);
for roll=1:NumRolls
diceValues = randi(6,[NumDice 1]);
totaldiceValue = sum(diceValues);
distribution(totaldiceValue) = distribution(totaldiceValue) +1;
end
valueMin = NumDice;
valueMax = 6 * NumDice;
bar(valueMin:valueMax, distribution(valueMin:valueMax), 'hist')
end
my graph is supposed to look like: http://i1308.photobucket.com/albums/s617/pingchu93/graph_zps0c8e0851.jpg
but i'm getting

The 1st graph has spaces and a difference x-axis scale which mine does not.
instead. any ideas? thanks!

bar(valueMin:valueMax, distribution(valueMin:valueMax))
with out the 'hist' option

What is the difference between the two graphs? The spaces between the bars? The title? The boldness of the lines? Be more specific.

sorry, i edited it in my function. The 1st graph has spaces and a different y-axis scale which mine does not

They both have x-scale from 1 to 6. What is different about that?

You can set the width of the bars:
bar(valueMin:valueMax, distribution(valueMin:valueMax), .75,'hist')
