i want both step fuction on same plot with different colors

clc
clear all
s=tf('s')
t=(1*10^4)*s+(3*10^5)
y=s^5+98*s^4+2194*s^3+3655*s^2+107100*s+3*10^5
g= t/y
a=(1.2*10^4)*s+(2.7*10^5)
b=s^5+98*s^4+2194*s^3+3655*s^2+107100*s+2.7*10^5
c= a/b *exp(-10*s)
 figure
 subplot(1,2,1)
hold oon
%  title('approximate responce')
 step(g)
 title('approximate responce')
  grid on
 subplot(1,2,2)

[Awais Saeed]

Try

figure
hold on
step(g, 'r')
title('approximate responce')
step(c, 'g')
grid on
legend('step(g)', 'step(c)')

or just simply

step(g,'r',c,'g')
