Plotting four lines in each of three subplots but only the last line is showing up

Summary: Ive got a [3x1] subplot structure. Trying to plot four lines on each plot. Subplot 1 plots just fine. For some reason the last two are only plotting the last of the four lines. Why isn't hold on working?
Code:
if true
% code
% Change directory
directory = pwd;
posdir = strcat(directory,'\Pos');
cd(posdir);
files = dir(posdir);
% Read in files
% Trial # 9, under threshhold, correct detect
filename1 = files(3).name;
[hip1,txt,raw] = xlsread(filename1,'Q:Q');
[shoulder1,txt,raw] = xlsread(filename1,'AS:AS');
[head1,txt,raw] = xlsread(filename1,'BU:BU');
% Trial 11, at threshhold, correct detect
filename2 = files(4).name;
[hip2,txt,raw] = xlsread(filename2,'Q:Q');
[shoulder2,txt,raw] = xlsread(filename1,'AS:AS');
[head2,txt,raw] = xlsread(filename1,'BU:BU');
% Trial 21, at threshhold, incorrect detect
filename3 = files(5).name;
[hip3,txt,raw] = xlsread(filename3,'Q:Q');
[shoulder3,txt,raw] = xlsread(filename1,'AS:AS');
[head3,txt,raw] = xlsread(filename1,'BU:BU');
% Trial 32, over threshhold, correct detect
filename4 = files(6).name;
[hip4,txt,raw] = xlsread(filename4,'Q:Q');
[shoulder4,txt,raw] = xlsread(filename1,'AS:AS');
[head4,txt,raw] = xlsread(filename1,'BU:BU');
% Subtract mean
x1 = (1:1:length(hip1))/250;
hip1 = (hip1 - mean(hip1));
hip2 = (hip2 - mean(hip2));
hip3 = (hip3 - mean(hip3));
hip4 = (hip4 - mean(hip4));
shoulder1 = (shoulder1 - mean(shoulder1));
shoulder2 = (shoulder2 - mean(shoulder2));
shoulder3 = (shoulder3 - mean(shoulder3));
shoulder4 = (shoulder4 - mean(shoulder4));
head1 = (head1 - mean(head1));
head2 = (head2 - mean(head2));
head3 = (head3 - mean(head3));
head4 = (head4 - mean(head4));
% Plot the data
figure(1)
clf(1)
grid on
sub1 = subplot(3,1,1);
hold on
plot(x1,hip1,'r');
plot(x1,hip2,'b');
plot(x1,hip3,'k');
plot(x1,hip4,'g');
xlabel('Time [seconds]');
ylabel('Displacement [mm]');
title('Vicon Hip Movement');
sub2 = subplot(3,1,2);
plot(x1,shoulder1,'r');
hold on
plot(x1,shoulder2,'b');
plot(x1,shoulder3,'k');
plot(x1,shoulder4,'g');
xlabel('Time [seconds]');
ylabel('Displacement [mm]');
title('Vicon Shoulder Movement');
sub3 = subplot(3,1,3);
plot(x1,head1,'r');
hold on
plot(x1,head2,'b');
plot(x1,head3,'k');
plot(x1,head4,'g');
xlabel('Time [seconds]');
ylabel('Displacement [mm]');
title('Vicon Head Movement');
legend('T09BET','T11ATC','T22ATI','T32ABT','Location','Best');
cd(directory);
end

I recommend Parent'ing all of your graphics calls http://uk.mathworks.com/matlabcentral/answers/22208-show-figure

If only one line shows up it could be that the data you are plotting for each of the lines is close enough that the lines are on top of each other at that scale.
