Plotting each iteration of a while loop

So the code is first supposed to create a 1x10 array of 0's and 1's. It is then supposed to convert that binary number to a decimal. Then that decimal number is supposed to be cut in half until it is less than 1. I need to find the number of iterations to become less than one. Then I need to plot the values of each iteration vs the iteration #. The code correctly gives me the number of iterations but I can't get it to plot. It just gives me a blank plot. Thanks

clear all

close all

clc

r = randi(([0 1]),1,10);

disp(r)

sr = num2str(r);

dec=bin2dec(sr);

disp(dec)

count = 0;

while(dec>1)

    dec = dec/2;

    count = count +1;

figure(2)

plot(count,dec)

ylim([0 1000]);

xlim([ 0 10]);

hold on

end

display(count);

The easiest thing would be to use the hold command to prevent the plot being overwritten every time you call plot. The general code structure would be:

figure
hold on

while CONDITION
  plot(STUFF)
end

For more information, check the documentation at https://www.mathworks.com/help/matlab/ref/hold.html.

The other thing to note is that the default plot style is a line with no markers... so if you want to plot individual points one at a time, then for example you can do them as red circular markers:

plot(STUFF,'ro');

Lets say i want the first 100 samples from my while loop to be plotted, how would I go about making that happen?
