Hi I'm Nhan from Vietnam. I'm a student.

I make a guide for my physics app(thermodynamics) but I have a problem in plot. I want to plot a graph of a thermo cycle. For example a cycle in the first 1)picture.

I first plot process 1 -> 2. then I plot 2 -> 3, it change the rate in x and y axis. The graph is too big and not tidy like the 1) picture above. – The second picture is my guide.

Could you please help me for this problem. thanks you very much.

If you don't like how it automatically decides the start and end of the x axis, you can specify it to be what you want with xlim():

xlim([0, 1.5]); % Or whatever numbers you want.

So you mean that you want the number of 1's in DG to be equal to edges?

I would say that if-condition is preventing some edges from being added, and you are assuming by looping from 1:edges that it will be satisfied every time. Your two calls to randi do not guarantee that the same edge has not already been added. You say you used a while-loop... Was it similar to the following?

while sum(DG(:)) < edges
  ....
end

That would guarantee the end-result that you seem to be looking for. If the loop never terminates, then there is bound to be a problem with the logic in the if, which looks more convoluted than perhaps it needs to be.
