i am draw two plot on image using impoint function.i want to move point of any plot using mouse. this time i am capable to move second plot point using mouse but not move first plot point. over requirement how to move both plot and get update position. when i move any plot point i have get all point update point position corresponding to plots. [xi{kk},yi{kk},but1]= myginput(1,'crosshair'); if but1 ==3 for i1=1:kk-1 pos1{i1}=getPosition(handles.h{i1}); % set(handles.h{i1},'hittest','off');

                    end
                    [Q]=hobbysplines(pos1);
                    jj2=1;
                    size(Q);
                    for jj=1:size(Q,2)
                        for jj1=1:size(Q{jj})
                            Q2=Q{jj};
                            Q2a(jj2,:)=Q2(jj1,:);
                            jj2=jj2+1;
                        end
                    end

                    % axis(handles.axes1);
                    handles.lh=plot(Q2a(:,1),Q2a(:,2), 'r');
                    ex1=1;

                    break
                end
                handles.h{kk} = impoint2(gca,xi{kk},yi{kk});
                setColor(handles.h{kk},'red');
                kk=kk+1;
i have enclosed image.
