How to plot three X & Y sets of points on the one graph from a text file

Hello,

I would like to know if there is a better way to plot three sets of data points on the same graph than what I have currently done. I am getting the points from the text file Ifile. Also I have not plotted the time that is associated with the x & y co-ordinates as I am unsure how to add this with each x & y set and how it would be displayed. This code works but seems a little clumsy, so I'm open to suggestions.

x = Ifile(:,2);
xx = Ifile(:,4);
xxx = Ifile(:,6);
y = Ifile(:,3);
yy = Ifile(:,5);
yyy = Ifile(:,7);
plot(x,y,xx,yy,xxx,yyy)

plot(  Ifile(:,[2,4,6])  , Ifile(:,[3,5,7])  )

Hi MattJ,

Yes I see that makes sense and is much cleaner.

Also, could you shed some light in how I would plot the time?

Obviously each x & y position has a time associated with it, however I not sure what to do if the data is not a pair as it is when plotting just x & y coordinates.
