How to plot a function file

Hello,

i wrote a function file about a dice game, and i want to plot the progress of the game with a stairs plot, but somehow i can't get the file to plot the results. the file itself works fine, but its just the plotting that i'm stuck with. I tried everything but i can't figure it out. I think i maybe need to attach a vector to the results and then plot this vector but i don't know how.

Hope someone can help me out.

This is what i have for the function file:

function [ y ] = dobbelspel2p

aantalworpen1 = 0;
waarde1 = 0;

while waarde1 < 40
    dobbelsteen1 = ceil(6*rand);
    dobbelsteen2 = ceil(6*rand);

      worp = dobbelsteen1 + dobbelsteen2;

     if dobbelsteen1 ~= dobbelsteen2
      waarde1 = waarde1+worp;
     end

      aantalworpen1 = aantalworpen1 +1;

end

while waarde1 < 51
    dobbelsteen3 = ceil(6*rand);

      if waarde1 + dobbelsteen3 <= 51;

          waarde1 = waarde1 + dobbelsteen3;
      end
  aantalworpen1 = aantalworpen1 +1;
  end

aantalworpen2 = 0;
waarde2 = 0;

while waarde2 < 40
    dobbelsteen1 = ceil(6*rand);
    dobbelsteen2 = ceil(6*rand);

      worp = dobbelsteen1 + dobbelsteen2;

     if dobbelsteen1 ~= dobbelsteen2
      waarde2 = waarde2+worp;
     end

      aantalworpen2 = aantalworpen2 +1;

end

while waarde2 < 51
    dobbelsteen3 = ceil(6*rand);

      if waarde2 + dobbelsteen3 <= 51;

          waarde2 = waarde2 + dobbelsteen3;
      end
  aantalworpen2 = aantalworpen2 +1;
  end

if aantalworpen1 < aantalworpen2
    y = 1;
    aantalworpen1
elseif aantalworpen1 > aantalworpen2
    y = 2;
    aantalworpen2
else aantalworpen1 == aantalworpen2
    y =0;
    aantalworpen1
end
   plot(waarde1,waarde2,'r-')
   hold on

end

But nobody really knows what you are trying to do here, what you are plotting and why. All we know is it is some form of dice "game", where we have no indication of the rules. Add that to unreadable, poorly formatted code, with no comments.

If you really want help in a timely fashion, then you need to make more of an effort. Or talk to your instructor, or to your fellow students.

@Thibault Franssens: Please explain clearly: What do you get now? What do you want to get? What have you tried (post the code instead of calling it "everything") so far and which problems do you have?

Given a vector y of dice outcomes, plot the stairwise graph like this:

y = [0,3,5,9,2];
X = [0,repelem(1:length(y)-1,2),length(y)];
Y = repelem(y,2);
plot(X,Y,'r');

the result is:
