How to plot section of a vector with a condition

1 次查看(过去 30 天)
Hello,
i am struggling with something. let me explain what exactly i need to plot. Suppose i have 4 vectors i.e Time, speed, torque, and power. say length of each vector is 15000x1. i want to plot time(x) vs speed(y),time(x) vs torque(y),time(x) vs Power(y). In all the three plots i don't want to shows points where power is less than a certain value. say power varies from 0 to 300. then in all the plots i don't want to show sections of plot whenever power is less than 225.
Thank you. -Amit

I'm not clear on whether you want to connect across the skipped points, or leave them out. Here's an example that illustrates both:
npts=1000;
x=linspace(0,4*pi,npts);
y1=cos(x);
y2=sin(x);
mask=y1>.5;
figure
subplot(2,1,1)
plot(x(mask),y1(mask))
subplot(2,1,2)
plot(x(mask),y2(mask))
figure
subplot(2,1,1)
ytmp=y1;
ytmp(~mask)=nan;
plot(x,ytmp);
subplot(2,1,2)
ytmp=y2;
ytmp(~mask)=nan;
plot(x,ytmp);

hello ! the above command did not work. as i wanted the power points less than 225 were not "masked" in the speed and torque plots. is there any other way?
thanks -Amit
