Changing a circle in resize-able GUI
显示 更早的评论
Im using this function to plot a circle:plot(two,one,'ro','MarkerSize',30); in a resize-able GUI how can I scale and change the radius of the circle?

You can't. Using a marker to draw a circle, the size is fixed. Better:
alpha = linspace(0,2*pi,100);
x = r * cos(alpha);
y = r * sin(alpha);
plot(x,y);
axis('equal');
Now resizing the figure changes the size of the circle directly.
