Draw a circle on matlab app designer?

I am making an app on Matlab app designer which consist on the following as you can see below: A graph panel and a Button, which when clicked, a circle that I have defined in the code is drawn. The issue here is that I have made two different codes that work perfectly in the command window but in app designer only works one, while the other one does not.
One of those both codes I have designed is the following one. Here I define the code of the circle I would like to draw when I click the button
As you can see, It is drawn perfectly
But this is the other code (much more easier to me) that doesn't draw well the circle
This is what it draws:
I would like to know how can I make the second code to draw the circle perfectly. Why doesn't it draw the circle? I don't understand why both of them work perfectly on the command window and thet don't on matlab app.designer.
Thank you very much!

Hi ErikJon, if the plot input is a matrix (e.g. your circ) "...the plot function plots the columns of the matrix (circ) versus their row number. The x-axis scale ranges from 1 to the number of rows in the matrix." So this is the designed behavior of the plot command for matrices. See the documentation here for plot(Y) for more info.
