Plot to figures without bringing the figure into foreground

figure;
ax1 = axes;
figure;
ax2 = axes;

x = 0; y = 0;

while ishandle(ax1) && ishandle(ax2)
    x = x + 1;
    y = y + 1;

      figure(1)
      scatter(x,y, 'MarkerEdgeColor', 'red')
      hold on

      figure(2)
      scatter(x,y, 'MarkerEdgeColor', 'blue')
      hold on
  end

In my script I have multiple figures, which are going to be updated in a loop. The figures have to be displayed, while the script is running. Unfortunately the currently updated figure is always popping in the foreground, which makes it impossible to monitor a certain figure. I understand that the calling of figure(1) and figure(2) causes this behaviour, but I how can I plot to these figures, without bringing the window into foreground?
