I plotted something but not sure why I can't adjust the linewidth of the result of the plot. I was able to change colors but linewidth doesn't change.
step(value_1);
set(value_1, 'LineWidth', 2);

Get the outputs of the step function, then plot them using a plot call:
[y,t] = step(value_1);
figure
plot(t, squeeze(y), 'LineWidth',2)
grid
The Control System Toolbox plot functions do not allow you to alter their properties easily, if at all.

This technique works for step, impulse, nyquist, and bode plots
LineWidth = 3;
s = tf(s)
sys = 1/(s+1)
figure; step/impulse/nyquist/bode(sys)
set(findall(gcf,'type','line'),'linewidth',LineWidth);
