Making a .gif from a for loop of plotted images

I have a few questions but first here is my code:

[file_list, path_n]=uigetfile('.csv','Grab the files you want to process','Multiselect','on')
if iscell(file_list) == 0
    file_list = (file_list);
end

N = length(file_list);
for i = 1:N
    filename = file_list{i};
    data_in = xlsread([path_n filename])
    
    hold on
    depth = data_in(:,1);
    Axial_stress = data_in(:,2);
    plot(depth, Axial_stress)
    xlabel('cm')
    axis auto
    ylabel('kbar')
    legend(filename)
    drawnow  
end

The overall goal is to make a .gif (if possible, otherwise the drawnow function will work) of the different graphs that are coming from this data but I have a few questions

1. How do i choose the colors for the lines? Any sort of line color choice function didnt seem to work for me, maybe I am missing something simple
2. Is it possible to diplay the currently plotting graph in the legend then once all the graphs are plotted, have a "total" graph that has all the lines in the legend?
3. How can I extract only the last 8 characters of the filename to use for the legend?
4. How can i have the x axis min be set, but let the x axis max and y axis min and max be floating and not dependant on the first file in my for loop?

To make a movie of the plots, see my attached demo.
