plotting the output of a for loop in a single color

So I have a series of x-intercepts that I need to turn into a plottable piecewise defined for sin(x) function, which I have been able to do with the following code:

years = [1350,1342,1302,1284,1204,1184,1144,1126,1096,1056,1036];
target = 1350 - years;

for i=2:11
    x_for = [target(i-1):0.1:target(i)];
    inc = target(i)-target(i-1);
    a = target(i-1);
    b = target(i);
    F = ((-1)^(i-1))*(inc)*sin((x_for-target(i-1))/inc*pi());
    plot(x_for,F)
    hold on
end
hold off

The problem is that the plot changes color every time it crosses the x-axis. Is there some way that I can get the plot to be all one color?

I don't know did i got the point or not,

But check does it work?

replace line 9 with this:

plot(x_for,F,'b')

Yup, that worked! I'm kinda sad that I didn't think of that myself...

Thanks!
