how do I shade area under graph with specific x interval?

27 views (last 30 days)
a=10;
t=0:0.1:200;
c_L=0.2.*(1-exp(1).^(-1/a.*t))
plot(t,c_L)
this is my graph and I just want to shade area between t=60:0.1:200;
what function should I use?

Try something like this
a=10;
t=0:0.1:200;
c_L=0.2.*(1-exp(1).^(-1/a.*t));
t_shade = 60:0.1:200;
c_L_shade = 0.2.*(1-exp(1).^(-1/a.*t_shade));
plot(t,c_L)
hold on
patch([t_shade fliplr(t_shade)], [c_L_shade zeros(size(c_L_shade))], ...
'r', ...
'FaceAlpha', 0.2)

It is used to draw a polygon, given the x and y coordinates.
