For example, Here is:
t=0:0.1:100;
x=sin(t);
plot(t,x)
So the plot will show a sin wave.
And now, I select the sin data between t=0:0.1:20, and decide to set the background color as red for the selected data between t=0:0.1:20.
So how to do this in the same plot?
Besides, how to do if I want to change the selected data color to red in the same plot?

plot() uses line objects, and those can only have one color per line.
There are a number of routines in the File Exchange that allow you to control color along a line. See http://www.mathworks.com/matlabcentral/answers/100246-how-do-i-create-a-2-d-or-3-d-line-that-changes-colors-along-the-data-points for one discussion
