Figures update from respective function from iterative process

i have a code with an iterative process. Each step is done by a different function to allow easy future enhancements. Most of the functions have a plot for visualization (4 separate figures). Now each iteration creates a new figure for each function. So 2 iterations create 8 figures, 3 create 12 etc. I would like that during each iteration the figure is updated (so new info gets added to the previous figure its own function). So i end up with 4 figures where all info is visible for all iterations per function. Is there an easy way to do this? Thanks in advance Bert

figure(1)
h(1) = plot(rand(10,1),rand(10,1),'r') ;
figure(2)
h(2) = plot(rand(10,1),rand(10,1),'g') ;

for i = 1:10
    set(h(1),'XData',rand(1,10),'YData',rand(1,10)) ;
    set(h(2),'XData',rand(1,10),'YData',rand(1,10)) ;
    pause(0.1)

end

the figures are now created in each function separately. This won't work like it is proposed. But maybe i can call in the globals and create the figures in the main program( that calls the functions), i guess that would be one way around it.

Also in the example code new data overwrites old data, i want to keep all previous data and add the new data to it
