plot two data sets over different time in the same plot

25 visualizzazioni (ultimi 30 giorni)
Hi,
I have two sets of data, say x = 1:10; y = [0,0,3:10] now I want to plot the data points over time t = 1:10 The thing is I do not want to see the 0-value points of y. or put in another way, I want to plot x over selected time t and y over t2. t2 = 3:10 in this case.
If I directly use y(t2) to add on, then the x axis for that plot will starts from 0, instead of 3 as desired!
Thanks, Howie

I am asking for two data sets(matrices), not functions. The rules are a little bit different. so if the time has a dimension different than the data, it simply cannot plot. Thanks, Howie

plot(t,x)
hold on
plot(t2,y)

yes! connecting all thye x; connecting all the y

connect x to y, or connect a point of x to the next point of x?

Here is an example of how it can be done:
t1 = linspace(0,2*pi,100);
t2 = linspace(pi,2*pi,50);
y1 = sin(t1);
y2 = cos(t2);
plot(t1,y1,t2,y2);
Gives you a plot of a sine (y1) and a cosine (y2), where the cosine only exists from pi:2*pi.

So here comes the problem. if I just do that, then 0-values of y will be plotted. but all I want is 3:10. I do not think I can do it just by selecting columns since my goal is to remove the points, without changing the position of the points
(I want the first point of y to be(3,3), not (1,3)).
Maybe I was doing it all wrong.

so why not just create a new array which stores only the required points?
