Hold all the legends while plotting multiple figures inside a for loop

A sample code is given below. Only the last legend entry is appearing in the plot. My attempt is to display all the legend entries in the plot. Hold all is not holding the legends but only coloring the plots.
clc
clear all
freq=20:20:100;
accln=[1 1 1 1 1;2 2 2 2 2;3 3 3 3 3;4 4 4 4 4;5 5 5 5 5];
data=[freq' accln'];
rms=zeros(5,1);
for i=1:5
rms(i)=sqrt(sum(data(:,i+1)));
end
for m=1:1:5
plot(data(:,1),data(:,m+1),'LineWidth',2)
hold all
ylim([0 6])
xlabel('Freq','FontSize',12)
ylabel('Accleration','FontSize',12)
set(gca,'FontSize',12)
leg=legend([num2str(m),'-',num2str(m+1),'s',' ',num2str(rms(m),'%.1f'),' ','grms']);
set(leg,'Location','SouthEast')
grid on
orient landscape
end
print('-dpdf','Hold legend.pdf','-r0');
