How to quickly create figures from a matrix with different specimen

I have some data that I am importing into MATLab. I have broken it down to the specimen number and the load it was experiencing. For example

ans =

    1.0000   21.5564
    1.0000   18.1025
    1.0000   17.8211
    1.0000   17.4481
    2.0000   25.0227
    2.0000   22.3182

How could I write a for loop or an if loop that automatically creates a figure that adds each specimen to the figure once the specimen number increases?

I answered my own question. The code is below for anyone that is ever going to reference this. It also splits it into two figures depending on the specimen number. That way there isn't one overcrowded figure.

 N=1; %Starts the for loop/ allows it to increase/match the specimen number
legendtext1=''; %creates a character so an array of each specimen number can be created for the legend
legendtext2=''; 
for A= N:9
 [A]=find(bayonetdata==N); %Creates matrix that will match the specimen number only
  if N>=5
     hold on
     figure(2)
     plot(1:length(A),bayonetdata([A(1):A(end)]',2)) 
     grid on
      legendtext2= [legendtext2; num2str(N)]; % creates the matrix for the plot legend numbering
  end
  if N<5
      hold on
      figure(1)
      plot(1:length(A),bayonetdata([A(1):A(end)]',2))  %plots the specimen number only test forces
    legendtext1= [legendtext1; num2str(N)]; % creates the matrix for the plot legend numbering
    grid on
  end
  hold off
 N= N+1 ; 
end
finallegend1=strcat(string('Bayonet '),legendtext1); %converts the legend to a string so that it can be manipulated easier within the legend and look cleaner
finallegend2=strcat(string('Bayonet '),legendtext2); %converts the legend to a string so that it can be manipulated easier within the legend and look cleaner
figure(1)
xlabel('Test Run')
ylabel('Ejection Force (kgf)')
grid on
title('Bayonet degredation over repeated housing ejections')
legend(finallegend1)
figure(2)
xlabel('Test Run')
ylabel('Ejecetion Force (kgf)')
grid on
title('Bayonet degredation over repeated housing ejections')
legend(finallegend2)
