MATLAB: Problem in creating animation plot 2D

Question

I am getting huge number of figure.but not the animation plot.What is the problem in my code? Can you please help me?

%% Animation of a graph a point P(x,y) which is variable connected to three fixed point A(6,9),B(20,38),C(49,25).

M=5000;
x=6:.01:49;                   % domain x.
y=9:.01:38;                   % domain y.
for i=1:length(x)
    for j=1:length(y)
        L=sqrt((x(i)-6)^2+(y(j)-9)^2)+sqrt((x(i)-20)^2+(y(j)-38)^2)+sqrt((x(i)-49)^2+(y(j)-25)^2);
        if L<M
            M=L;
            a=x(i);
            b=y(j);
            p = [6 20 49];                % x coordinates of three fixed points A, B, and C.
            q = [9 38 25];                % y coordinates of three fixed points A, B, and C.
            figure('color','white');
            hold on;
            for n = 1:length(p)
                plot([p(n) a],[q(n) b],'color',[0 0 1]);
                myChar = char(64+n);
                text(p(n)+1,q(n),myChar);
            end
            plot(p,q,'o','markerfacecolor','k','markeredgecolor','none', ...
                'markersize',4);
            plot(a,b,'o','markerfacecolor','k','markeredgecolor','none', ...

            text(a+0.5,b+0.75,'P');
            xlabel('x');
            ylabel('y');
            drawnow
            pause = .01;
        end
    end

Answer 1

Put figure out side of the for loops

figure('color','white');
