I want to change xlim,ylim of axes , and draw a circle at the point I chose when I click on a place in the axes in GUI

Answer 1

[KSSV]

th = linspace(0,2*pi) ;
R = 1. ;  % Radius of circle 
x = R*cos(th) ; y = R*sin(th) ;
figure
axis([-5 5 -5 5]) ;   % cahange axes here to your desired 
[Cx,Cy] = getpts() ;   % click where you want to draw circle; double click to exit 
hold on
% plot the circles 
for i = 1:length(Cx)
    plot(Cx(i)+x,Cy(i)+y)
end
axis equal
