plot scattered data in order (matlab) -


i have scattered data want plot. line of plot not following trend of scattered data. 

a=[1.3476 0.7015 0.2449 0.3402]; b=[0.1 0.2 0.3 0.3];  plot(a,b) figure scatter(a,b,'marker','x')

a , b vectors contain small number of data points have.

as seen, line in plot(a,b) not following right order.

i need line passes through points left right appear in figure when use scatter command.

thanks!

if understand correctly: sort a , apply same sorting b:

[sa, ia] = sort(a); sb = b(ia); plot(sa,sb)
