How do I plot multiple names and rankings and find them?

So i have the user input the baby names (min 5 max 7) then I save the baby name and make sure the first letter is capitalize then I find the baby name in my baby name file. From there how do I also find the ranking and plot? I am so lost on how to use strings and such here is my code

    % Display a menu and get a choice
      choice = menu('Choose an option','Exit Program','Load Data File','Plot Family Graph');
      % as you develop functions, add buttons for the here

      while choice ~= 1
          switch choice
             case 0
                 disp('Error - please choose one of the options.')
                 % Display a menu and get a choice
                 choice = menu('Choose an option','Exit Program','Load Data File','Plot Family Graph');
             case 1
                 %exit
             case 2
                 % Load into one baby name and one ranking by using the function
                      [names, rankings] = Read_names_file();
                      if isempty(names)
                          return
                      else
                          disp('Data loaded.')
                      end
                 %open menu options again
                choice = menu('Choose an option','Exit Program','Load Data File','Plot Family Graph');
             case 3
                %plot family graph
                numberNames = input('Type in the number of names you want to research (min 5, max 7):');
                if numberNames > 7 || numberNames < 5;
                    fprintf('Invalid number try again \n')
                    numberNames = input('Type in the number of names you want to research (min 5, max 7):');
                else
                    for i = 1:numberNames;

                      babyName = input('Please enter a baby name: ','s');
                      babyName = [upper(strcat(babyName(1))) lower(strcat(babyName(2:end)))];

                    end
                end 
                 fprintf('%s \n', babyName);
                 %ind = find(ismember(names, babyName));
                 %babyPlot = strcmp(names, babyName);
                 x = strmatch(babyName, names);
                      if isempty(x)
                          disp('empty')
                      end

                  y = strfind(babyName,rankings , 'extract');
                      if isempty(y)
                          disp('empty')
                      end

                 figure
                 plot(x,y)

          end

                 choice = menu('Choose an option','Exit Program','Load Data File','Plot Family Graph');  

      end

The question is not clear

[Sarah Huynh]

i'm sorry, i'm trying to make a graph that plots info from my file. in that file contains baby names and their rankings.

In general I have made a menu to give the user the options to load my file

then after the file is loaded i then give the user an option to plot the graph

after that I ask how many names do they wish to see on the graph

problem:

I do not know how to ask the user to give me the names and save it into different variables.

I only am able to save one name,

after that I do not know how to find the name they have inputed to find the names on my loaded file to plot the graph.

babyName{i} = input('Please enter a baby name: ','s');
babyName{i} = [upper(strcat(babyName{i}(1))) lower(strcat(babyName{i}(2:end)))];
