I am using ishghandle in while loop, So I want to animate two plots in single ishghandle, Can I animate hdots(1) and hdots (2) ? Thanks in advance

    npts=1;center=[0 0];radius=1000;
    % Initial direction/velocity of the points
    velocity = 28.8/3.6;
    % Create random starting locations within the circle
    Totaltime =10;
   
    theta = rand(npts, 1) * 2*pi;
    g = 0.5 * radius + 0.5 * radius * rand(npts,1); 
    X_x=center(1)+g.*cos(theta);
    Y_y=center(2)+g.*sin(theta);
    XY = [X_x ,Y_y];
    theta2 = rand(npts, 1) * 2*pi;
    g2 = 0.5 * radius + 0.5 * radius * rand(npts,1); 
    X_x2=center(1)+g2.*cos(theta2);
    Y_y2=center(2)+g.*sin(theta2);
    XY2 = [X_x2 ,Y_y2];
    hfig = figure('Color', 'w');
    hax = axes('Parent', hfig);
    hdots(1) = plot(XY(1,1),XY(1,2),'Parent', hax,'Marker', '.','Color', 'k','LineStyle', 'none','MarkerSize', 10);
    hold(hax, 'on')
    axis(hax, 'equal')
    hdots(2) = plot(XY2(1,1),XY2(1,2),'Parent', hax,'Marker', '.','Color', 'r','LineStyle', 'none','MarkerSize', 10);
    hold(hax, 'on')
    axis(hax, 'equal')
    
        % Plot the circl e as a reference
    t = linspace(0, 2*pi, 100);
    plot(radius * cos(t) + center(1),radius * sin(t) + center(2))
    
    while ishghandle(hdots) % Can I animate hdots1 and hdots 2
    direction = rand(npts, 1) * 2 *pi;
    
    [XY, direction] = step(XY, direction, velocity, radius, center);
    % Plot the dots as black markers
    % Update the dot plot to reflect n ew locations
    set(hdots, 'XData', XY(1,1), 'YData', XY(1,2))
    % Force a r edraw 
    drawnow
    pause (1)
   end
