MATLAB: A question about plotting

plotplotting

Q.
I have many S seperately with different on lines on the plot, lines with different k have different colours and shapes. I change the coding to make it more efficient, but now I have no idea how to have a same plot of my original one.
1/ my original codes for S and k, and my original plotting codes
I = 1:100
k03 = 0.3
k1 = 1
k3 = 3
k5 = 5
k8 = 8
k13 = 13
k15 = 15
k18 = 18
k23 = 23
k25 = 25
k28 = 28
S03F = k03*log(I)
S1F = k1*log(I)
S3F = k3*log(I)
S5F = k5*log(I)
S8F = k8*log(I)
S13F = k13*log(I)
S15F = k15*log(I)
S18F = k18*log(I)
S23F = k23*log(I)
S25F = k25*log(I)
S28F = k28*log(I)
figure(1)
hold on
plot(S03F,'co-','markersize',3,'Displayname','k<1');
plot(S1F,'gs-','markersize',3,'Displayname','k=1');
plot(S3F,'gs-','markersize',3,'Displayname','k=3');
plot(S5F,'gs-','markersize',3,'Displayname','k=5');
plot(S8F,'gs-','markersize',3,'Displayname','k=8');
plot(S13F,'md-','markersize',3,'Displayname','k=13');
plot(S15F,'md-','markersize',3,'Displayname','k=15');
plot(S18F,'md-','markersize',3,'Displayname','k=15');
plot(S23F,'rp-','markersize',3,'Displayname','k=23');
plot(S25F,'rp-','markersize',3,'Displayname','k=25');
plot(S28F,'rp-','markersize',3,'Displayname','k=28');
title({'Stevens Law:Power Function'…
'\fontsize{9}Relaitionship Between Subjective and Actual Stimulus Magnitude'…
'\fontsize{9}\color{blue} Under Various k Value'});
lgd = legend ('Location','northwest');
lgd.NumColumns = 4;
lgd.FontSize = 6;
hold off
2. the codes now for S and k
I = 1:100;
kV = [0.3;1;3;5;8;13;15;18;23;25;28];
SV = kV.*log(I)

Hi,
if you want to mantain your plot design, you can indexing your array. As example:
figure(1); hold on:
plot(SV(1), 'co-','markersize',3,'Displayname','k<1');
plot(SV(2),'gs-','markersize',3,'Displayname','k=1');
...
hold off
