How to connect the dots

I am plotting with plot(x,var(x),'o')
var(x) is the variance. These points (x,var(x)) are the discrete points in a x-var(x) plane. How write the plot command so the there discrete points be joined by st. line (or a smooth curve)

variance essentially applies to an unordered list of points (a "multi-set"): each of the unique permutations of x necessarily has the same variance. That would not often be referred to as "discrete points" in the plane.

Dunno if this is what you want..
DO realize that var(x) is a single scalar value as the variance of x
x=rand(10,1)
y=repmat(var(x),length(x),1)
plot(x,y,'Marker','o')

You can use
plot(x,var(x),'-o')
to connect the dots. This draws a straight line from one to the next.
EDIT: As Thomas pointed out, var(x) returns a single value, so the above command doesn't connect the dots without using repmat as Thomas suggested to create a vector of matching size.
