Diagonal Line appearing in plot

I am using MATLAB R2016b on Windows10. Whenever I use (1)there appears a a diagonal line in the plot. I have already tried using the code (2)(to deal with the issue) mentioned in some other similar post but its not addressing the issue. Can somebody suggest a solution?

(1)

        x = linspace(0,12);
         y = linspace(0,12);
         plot(x,y);

(2)

         set(gcf, 'Renderer', 'painters')
         set(gcf, 'Renderer', 'opengl')
         opengl software

I don't understand. So you make 100 points where x equals y exactly, and then plot them with

x = linspace(0,12);
y = linspace(0,12);
plot(x,y);

and you're surprised that you get a line where x=y. Why? What do you think it should look like? What else are you expecting other than a straight line at 45 degrees?

What an incredibly rude response.

In his defence, the question is incredibly senseless

I am puzzled as well.

this guy always answers very sarcastic, you must have really serious personal issues, maths are like your safe place, you are a shame to this comunity

Yeah I was going to say the same. People use this forum to learn, not receive condescending answers. Ignore it if you think they can google an answer themselves, don't let 'MVP' get to you.

Others in this thread were also just as confused as I was at the initial question - it's not just me (click the link above to show the older comments).
